Etobicoke Creek Watershed 


Implementation Plan 

1.0 Introduction 

Lester B. Pearson International Airport (LBPIA) is 

the largest single land use within the Etobicoke 

and Mimico creeks watersheds, and comprises 

approximately six and seven per cent of the 

watersheds respectively. The Greater Toronto 

Airport Authority (GTAA) lands straddle three 

of the four Etobicoke Creek subwatersheds (all 

except Little Etobicoke Creek subwatershed), 

with the downstream confluences of the Upper 

Etobicoke and Spring creeks subwatersheds, as 

well as the upstream origin of the Lower Etobicoke 

Creek subwatershed, all located upon the GTAA 

property. The airport’s unique position as the 

nexus of the three major subwatersheds means 

that the key recommendations of this report 

have special significance to the airport lands, and 

conversely, as do the airport’s operations upon the 

subwatersheds, both upstream and downstream. 

The GTAA and Toronto and Region Conservation 

(TRCA) share a mutual interest in the Etobicoke 

Creek and have a good working relationship 

regarding its protection and enhancement. Greater 

Toronto Airport Authority staff have contributed to 

the Etobicoke-Mimico Task Force, the development 

of Greening Our Watersheds: Revitalization Strategies 

for the Etobicoke and Mimico Creeks, currently sit on 

the Etobicoke-Mimico Creek Watersheds Coalition 

and have worked together to create the GTAA


Integration Etobicoke Creek and Implementation 

Watershed 

Living City Project as an interdisciplinary approach 

to watershed management within this area of the 

Etobicoke and Spring creeks. 

The GTAA Living City Project is a major undertaking 

involving four main components: 

1. Terrestrial Natural Heritage 

The Terrestrial System inventory and 

modeling for the study area (LBPIA Wildlife 

Control Area) includes management 

recommendations, identification of 

potential/targeted natural cover and priority 

restoration and enhancement sites to meet 

TRCA’s local, as well as watershed, targets 

for the terrestrial system. 

2. Aquatic Ecosystems 

The Etobicoke Creek Watershed Fisheries 

Management Plan (FMP) presents 

management recommendations for target 

species at a subwatershed scale and 

restoration opportunities for priority aquatic 

habitat in close proximity to GTAA lands. 

3. Stormwater Management 

The Stormwater Management Study 

includes five components: A Modelling 

Assessment of Runoff Water Quality 

Management in Etobicoke Creek for 

Catchment 219, which is a representative 

catchment upstream of the GTAA property; 

the Etobicoke Creek Watershed Spills 

Mapping Study; a Fluvial Geomorphology 

and Erosion Assessment of Etobicoke 

Creek; off-site and on-site stormwater 

management opportunities, and the TRCA 

Hydrology Model Update. These reports 

provide the basis for improved stormwater 

controls in the watershed. 

4. Integration and Priority Implementation 

Recommendations 

Key recommendations from the above 

studies are spatially and conceptually 

integrated to ensure land uses, 

water quality, fisheries and terrestrial 

opportunities are prioritized within the 

study area. Potential partnerships and 

community outreach opportunities for 

implementation are provided as part of the 

Business Stewardship Program. 

Study Areas 

The study areas for each component provide 

multiple scales of addressing watershed 

management, as seen on Map 1. The Fisheries 

Management Plan (FMP) takes a watershed-wide 

scale in its recommendations, the Terrestrial Natural 

Heritage Report provides recommendations 

centered upon the GTAA study area 1* and the 

Stormwater Management Report looks at upstream 

catchments draining into GTAA lands. While these 

study areas may vary, their impact follows a process 

to realize watershed-wide targets.

2.0 Study Components 

and Findings 

Aquatic Ecosystems – Etobicoke 

Creek Fisheries Management 

Plan (FMP) 

The FMP provides recommendations to protect 

and enhance the aquatic ecosystem within the 

watershed and serves as a guide for land-use 

planners, consultants, farmers, private landowners, 

land developers, anglers and nature enthusiasts. 

It includes management objectives, target species 

and various implementation strategies to improve 

the ecological integrity of the aquatic ecosystem at 

a subwatershed scale. 

Key findings of the report include: 

• Fifty-two fish species have historically been 

found in Etobicoke Creek, of which only 28 

were captured in 2001 and 20 in 2004. The 2004 

surveys identified three species not previously 

documented in the watershed. 

• Of note is the historical presence of mottled 

sculpin and redside dace, as these are sensitive 

species – neither of these species was present 

in surveys completed in 2000 and 2001. All of 

the other species found are tolerant species 

indicative of degraded conditions. 

• Aquatic habitats in the Upper Etobicoke and 

Spring creeks are in relatively good condition, 

while the more urbanized Lower and Little 

Etobicoke creeks subwatersheds are more 

degraded.



Watershed 

• The Etobicoke Creek has a total drainage area 

of 211 square kilometres and 16.5 per cent, or 

approximately 45 kilometres of the watercourse, 

has woody riparian vegetation. This lack of 

quality riparian cover negatively affects water 

quality and habitat. 

• Analyses of historic data indicate that over 7.4 

per cent of the watershed was once wetland. 

Presently, only two wetland complexes have 

been evaluated and they, combined with all 

other identified wetlands, comprise only 0.8 per 

cent of the watershed. 

• Only two small reaches make up small riverine 

coldwater habitat with drainage areas less than 

10 square kilometres. 

• The combination of considerable flows, and 

reduced invertebrate diversity and density are 

likely contributors to the substantial decline in 

diversity and aquatic community. 

• The presence of in-stream barriers negatively 

affects the quality of the habitat and the 

potential for access by both fish and 

invertebrate species. 

• Discovery of coldwater habitats in the 

headwaters of the Upper Etobicoke Creek 

subwatershed and Spring Creek subwatershed. 

These key findings are spatially interpreted on 

Map 2. 

Terrestrial Natural Heritage 

The Terrestrial Natural Heritage (TNH) study 

employed TRCA’s Terrestrial Natural Heritage 

System Strategy (TNHSS) methodology and 

modeling at a more local scale to provide 

recommendations for protecting and restoring the 

target natural system within the GTAA study area. 

The scope of the inventories and proposed 

restoration work extend beyond GTAA lands to 

surrounding areas of the Etobicoke Creek corridor 

that include the LBPIA Wildlife Control Area. 

This is consistent with contemporary ecosystem 

management and landscape context approaches 

for the conservation and restoration of biodiversity. 

The important message that permeates this report 

is that the health of the natural system is measured 

at the regional or landscape scale, and specific 

sites must be considered for their benefits to the 

larger system. The concern is the cumulative loss of 

natural cover where little things quite literally add 

up to the big things. 

Key findings of the report include: 

• The health of natural system ultimately depends 

most directly on the quantity of land with 

natural cover. The GTAA study area comprises 

8,465 hectares and features 870 hectares of 

natural cover. This represents 42.5 per cent of 

the 2,046 hectares of total natural cover in the 

Etobicoke Creek.



Map 2

entire Etobicoke Creek watershed. This indicates 

the GTAA study area contributes immensely 

to the overall health of the natural system 

within the watershed. 

• The state of the terrestrial system within the 

GTAA study area was evaluated as “poor” to “very 

poor” during the landscape analysis. This is not 

surprising given the matrix influence of airport 

operations and major transportation corridors. 

• Surrounding any habitat patch is a matrix of 

land-use types, ranging from agricultural to 

urban uses, which influence the ecological 

function of the system. Adjoining natural cover is 

beneficial, while urban uses often exert a strong 

negative influence, such as hydrological change, 

introduction of invasive species, and trampling 

and collection by local citizens. 

• The majority of habitat patches in the study area 

receive a “poor” to “fair” score for both patch size 

and shape. The GTAA study area does provide 

for a lot of natural cover; however, little forest 

interior (100 metres from forest edge) exists. 

• Distribution of habitat and natural cover is 

weighted to the north, with serious deficiencies 

in the south. The south cannot support 

appropriate species of concern in its urban 

matrix, thus any change in higher quality 

portions in the north should be considered to 

what has already been lost. 

• Only one patch features forest interior in the 

GTAA study area. Located south of Highway 

401, it supports the highest diversity of flora 

and fauna species of conservation concern, 

and is the least disturbed within the study 

area. The existence of this patch demonstrates 

large habitat patches with good shape can 

continue to support sensitive species in an 

urbanized environment. 

• Aside from riparian linkages, connectivity 

between other natural patches in the GTAA 

study area are insufficient for the maintenance of 

terrestrial species and ecological services. 

• Priority Candidate Restoration Sites identified 

and ranked from high to low, based on ecological 

gains to the terrestrial system and immediacy 

for action. These Candidate Restoration Sites are 

included in Appendix 1 and are spatially related 

on Map 3. 

Stormwater Management 

One of the biggest issues facing the Etobicoke 

Creek is stormwater management (SWM). Significant 

portions of the watershed were developed prior 

to SWM practices and in some places uncontrolled 

discharges go directly into the creek, leading to 

degraded water quality and increased erosion. 

Restoring native vegetation communities is a key component 

of rebuilding a sustainable natural heritage system that has 

begun to fail after suffering decades of cumulative losses, and the 

impacts of human use and development.



Watershed 

Discussions with GTAA staff have revealed 

that there are very limited stormwater retrofit 

opportunities on GTAA lands. Approximately $150 

million has been invested over the last several years 

on numerous water quality enhancement projects, 

including state-of-the-art underground treatment 

tanks, a two-celled treatment wetland and many 

other associated structures. There are few, if 

any, remaining feasible retrofit opportunities for 

effective stormwater management. As a result, the 

study of on-site retrofit projects was not advanced. 

A number of studies contribute to this report and 

were conducted from a variety of spatial scales, 

from site-specific to catchment to reach and 

watershed, and are spatially interpreted on Map 4. 

These studies and their key findings include: 

• Toronto and Region Conservation Hydrology 

Update – an update of the Etobicoke Creek 

hydrology model to a continuous model that 

identifies existing flow rates, volumes of runoff, 

future condition rates and volumes based on 

projected development scenarios. 

new wet pond location has been identified for 

construction through the Catchment 219 Study 

within the City of Mississauga and three ponds 

were identified for retrofit within the City of 

Brampton. In addition, 15 outfalls have been 

identified for retrofit within the City of Brampton 

and five in the City of Mississauga. 

• Spills Mapping Study – most oil and chemical 

spills occurred in industrial areas of Brampton 

and Mississauga, with spill hot-spots being 

the areas upstream of GTAA lands bounded 

in the west by Highway 401, Highway 410 and 

Derry Road, and to the north by Dixie Road and 

Highway 407. Due to presence of sand-clay and 

clay-loam soil in the watershed, groundwater 

pollution associated with the soil-impact spills 

may not be very significant. Human error and 

equipment failure were the primary reasons for 

the spills. 

• Fluvial Geomorphology Study and Erosion 

Assessment – data from 18 detailed study sites 

found that in the upper part of the watershed, 

the critical discharge values represented flow 

conditions well above bankfull conditions, while 

the lower reaches of the watershed experience 

erosive flow conditions much more frequently. 

These results will be used for a number of 

different purposes including siting of valleyland 

restoration projects, assessing erosion-prone 

areas for remediation works and, in the short 

term, this information can be used to prioritize 

stormwater management retrofit opportunities 

to maximize erosion control benefits. 

• Stormwater Management in the Watershed – 

the cities of Brampton and Mississauga have 

both undertaken retrofit studies that identify 

existing stormwater management ponds and 

uncontrolled storm sewer outfalls where it is 

feasible to implement works to enhance quality 

and quantity. Upstream of the GTAA lands, a 

Porous pavement.

Wet ponds can be designed as an efficient end-of-pipe facility 

for water quality, erosion and quantity control. They may also be 

designed with recreational, and other values in mind contributing 

to the character of a community and becoming the centrepiece of 

a new development. 

• Catchment 219 Stormwater Management 

Modeling, Assessment and Characterization 

Study – a catchment study focusing on a 

“characteristic” sewershed within the study 

area was completed in order to develop 

recommendations for the other upstream 

sewersheds. Catchment 219 was “characteristic” 

in that it includes various elements from a 

variety of similar industrial catchments, and 

therefore the results (and treatment scenarios) 

could be implemented in other areas of the 

watershed. The study produced nine treatment 

scenarios providing associated costs of increased 

stormwater controls and impacts on stormwater 

quantity and quality.

3.0 Key Recommendations 

The key recommendations from all three 

component studies provide direct and indirect 

benefits to the GTAA study area and the watershed 

as a whole. The key recommendations from each 

report and their associated benefits to the GTAA 

lands are provided in Table 1.

Watershed 

Table 1 

Key Recommendations and Benefits to Greater Toronto Airport Authority 

No. Key Recommendations Overall Benefits to GTAA 

Aquatic Eco-Systems – Etobicoke Creek Fisheries Management Plan 

1. Protection and management of small riverine coldwater habitat just upstream of the airport for 

the target species of sculpin. 

2. Protection and enhancement of Etobicoke Creek habitat (upstream and downstream of 

GTAA) for darters and smallmouth bass in the small and intermediate riverine warmwater 

management zones. 

3. Riparian vegetation (dense woody vegetation to be established 30 metres on each bank). 

- Improved water quality and 

erosion controls. 

- Protection of wildlife and 

habitat. 

- Priority habitat banking 

locations and habitat 

information for further runway 

construction on airport lands. 

4. Natural channel design during alterations (the GTAA has already employed natural channel 

design during the Spring Creek realignment and it is anticipated that it will continue with future 

projects). 

5. The protection of baseflow through limiting or mitigating imperviousness in this area. 


1. Restoration and creation of natural corridors: 

- Natural corridors to link existing patches in the GTAA study area should be maintained and 

enhanced whenever possible. 

- Linkages need to be restored between the GTAA terrestrial system and natural areas 

surrounding the study area, as suggested in TRCA’s regional target system. 

- Enhance connections between forest and wetland habitats. 

- Establish an east-west connection on table lands. 

2. Natural cover in the south needs to be preserved and increased to ensure there is an even 

distribution of more desirable quantity of natural cover throughout the watershed. 

3. Future urban development should minimize stresses on the natural heritage system during 

development and redevelopment. 

4. Flora and fauna inventories should be consulted, as any change or alteration of habitats could 

result in the loss of habitat-dependent species. 

5. Restoration activities should be undertaken to increase the size, improve the shape of existing 

habitat patches and promote forest interior conditions to support sensitive species and 

important ecological processes. 

6. Land securement where possible in order to meet system targets. 

7. Expansion of the target natural heritage system. 

8. Mitigation of the negative effects of the matrix (surrounding land use) by ensuring that new 

development and expansion take into consideration the location of sensitive species and 

communities to mitigate all potential threats. 

- Protection and enhancement of 

habitat. 

- Provide for the movement, 

dispersal and regeneration of 

flora and fauna species within 

the study area. 



- Aid in the implementation of 

the LBPIA Wildlife Control Area 

recommendations. 

- Several opportunities to restore 

GTAA-owned lands including 

agricultural fields. 

- It is well understood that 

large manicured fields and 

agricultural crops create a 

considerable hazard 

in attracting medium to large 

flocking species (e.g., Canada 

geese, 

ring-billed gulls) into the 

vicinity of an airport. In 

light of this management 

consideration, it is 

recommended soybean fields 

and open meadows located 

in the western vicinity of the 

airport around the airstrips 

would be better managed as 

forest and woodland habitat. 

9. That within the landscape surrounding the airport, restoration of natural forested cover should 

take preference over manicured, open habitat and agricultural crops such as soybean and corn.

Mississauga. 

- Tributary #2 (east branch) between Queen Street and Highway 407 in Brampton. 

- Tributary #2 in Mississauga north of Derry Road between Dixie Road and Torbram Road. 

2. An ongoing system for monitoring and documenting spills within the watershed should be 

developed in order to assess the state of the watershed. 

3. New wet stormwater pond to be constructed at Dixie Road for quantity and quality control. 

4. Retrofit Upper Nine Pond and Grey Stoke Pond in the City of Brampton to wet ponds for quality 

control. 



- Protection of wildlife and 

habitat enhancement. 

- Improved knowledge of spills 

for industrial/commercial area 

surrounding LBPIA to assist 

with spills prevention. 

- Improved watershed practices 

of local industry upstream and 

surrounding airport lands. 

- Improved flows in the 

Etobicoke and Spring creeks 

as they approach and flow 

through airport lands. 

5. Fifteen stormwater outfalls within the City of Brampton and five in the City of Mississauga 

should be retrofitted for quantity and quality controls. 

6. All residential and industrial areas should be serviced with wet ponds for quality controls. 

7. Both existing and proposed ponds should be considered for chemical and bacterial removal if 

monitoring reveals that in-stream water quality targets cannot otherwise be achieved. 

8. Industrial source controls should be encouraged on surrounding institutional/commercial/ 

industrial (ICI) properties. 

9. Residential source controls should be encouraged and education programs developed. 

10. Municipalities should update their water management strategies as new innovations in 

stormwater management become available.

4.0 Implementation 

In order to realize the desired benefits and all 

recommendations, a long-term implementation 

strategy is required. However, as a first step, 

a five-year implementation plan for priority 

recommendations is provided that has two 

focus areas: 

1 Focus Area 1: Catchment 219 – Water 

Quality/Quantity and Habitat Restoration 

2 Focus Area 2: GTAA Study Area Terrestrial, 

Aquatic and Water Quality Enhancements 

Focus Area 1: Catchment 219 – 

Water Quality/Quantity and 

Habitat Restoration 

The priority area for restoration is the Catchment 

219 sewershed upstream of GTAA lands. As a 

sewershed the area provides drainage for water 

that would have under natural conditions traveled 

via rivers, streams and underground flow, but now 

due to urbanization travels to watershed outflows 

through municipal storm sewers. 

A largely industrial area, with a small residential 

component in the north, Catchment 219 is upstream 

and west of GTAA lands. The area has a history 

of industrial spills and visibly poor water quality 

(Li, 2003). Given GTAA’s work to improve stormwater 

outflow from their site, concentration on this 

21



Watershed 

upstream source of pollutants offers an opportunity 

to further improve water quality and watershed 

health on both GTAA lands and downstream. 

Utilizing a sewershed model has numerous 

benefits, including: 

• A science-based approach to watershed 

management. 

• The opportunity to have measurable results 

based on a measurable land area. 

• The ability to monitor improvements and 

provide further opportunities. 

The most important benefit provided is the ability 

to monitor. This benefit derives from the fact there 

are defined boundaries for the drainage area that 

allow for monitoring of water quality from one end 

to the other through the sewershed. The ability 

to monitor not only provides the opportunity 

to ensure successful watershed management 

practices, but also assists in directing funding to 

areas in need of attention. 

The Catchment 219 study area provides potential 

hydrologic and water quality benefits from the 

implementation of stormwater management 

measures across the catchment, as well as estimated 

costs associated with the implementation and 

operation of these programs in the area. These 

opportunities also have the potential to be 

combined with spill control programs, potential 

terrestrial natural heritage sites and restoration 

strategies from the FMP, to realize benefits on a 

watershed-wide scale. 

The recommendations, priority rankings and 

cost estimates provided in Table 2 and spatially 

related on Map 5 are based on Scenario 7 from 

the Modelling Assessment of Runoff Water Quality 

Management in the Etobicoke Creek Catchment 

219 report. Scenario 7 provides the most effective 

plan for addressing stormwater quality considering 

cost constraints, while offering opportunities 

for upgrading. 

Recommendations for Catchment 219 are below 

and combine the findings of the three component 

reports: 

• The Upper Nine stormwater pond in the City of 

Brampton should be upgraded to a wet pond for 

quality controls. 

• A new wet pond for both quantity and quality 

controls should be constructed east of Dixie 

Road to collect stormwater east of Highway 410. 

• Industrial source controls, such as roof-top 

gardens, rerouting of parking area runoff to grass 

and oil/grit separators, should be encouraged. 

• Residential/commercial source controls, such as 

downspout disconnects, pervious paving and 

rainbarrels, should be encouraged. 

• A spills monitoring and control system should be 

installed at strategic sites in Catchment 219. 

• A spills response system should be implemented. 

• One hundred per cent of riparian habitat 

vegetated (this is identified as a long-term goal 

beyond the 5-year implementation). 

• Seventy-five per cent of riparian habitat to be 

forested (this is identified as a long-term goal 


A full implementation schedule, with priority 

rankings and cost estimates, based on these 

recommendations can be found in accompanying 

Table 2. 

Focus Area 2: GTAA Study Area Terrestrial 

and Aquatic Enhancements 

This restoration focus takes the recommendations 

from the Terrestrial Natural Heritage Report, FMP 

and stormwater report for the GTAA study area 

(excluding Catchment 219) to provide opportunities 

for terrestrial and aquatic enhancements. 

Restoration Opportunities 

The GTAA study area includes almost 40 per cent 

of the Potential Natural Cover identified within 

the TNHSS for the Etobicoke and Mimico creeks 

watersheds. Restoration, enhancement and 

securement of terrestrial system in this area is 

important to meeting the overall targets (minimum

11 per cent in Etobicoke Creek and eight per cent 

Mimico Creek) for a healthy TNHS in the Etobicoke 

and Mimico creeks watersheds. Based on this need, 

Candidate restoration sites were selected using the 

following criteria: 

1. Presence of species of conservation concern 

that would benefit from an expansion of 

habitats and increase/improvements to 

existing patch size, shape or connectivity. 

2. Presence of vegetation communities 

of concern that would benefit from an 

expansion of its current size or by restoring 

connections to other natural areas. 

3. Area represents a significant gain to the 

targeted terrestrial natural system in such a 

way that improvements to overall landscape 

watershed function area achieved. 

The priority Candidate sites have been ranked 

from high to low, based on ecological gains to 

the terrestrial system and immediacy for action. 

However, all areas identified in Appendix 1 as 

Candidate Sites represent excellent opportunities 

for restoration work if opportunities arise. 

Further recommendations include: 

• Spills control/response system for area between 

Queen Street and Highway 407. 

• A spills monitoring program. 

• One hundred per cent of riparian area vegetated 

(this is identified as a long-term goal beyond the 

5-year implementation). 

• Seventy-five per cent of riparian area to be 

forested (this is identified as a long-term goal

estimates from the Terrestrial Natural Heritage 

Report, FMP and stormwater report, can be found in 

accompanying Table 3 and are interpreted spatially 

on Map 6. 

In order to begin to address the key areas of interest 

noted above, aquatic sites have been integrated 

at a subwatershed scale with a number of the 

Candidate restoration sites using TRCA’s Habitat 

Implementation Plan (HIP) methodology. These 

integrated restoration opportunities can be viewed

5.0 Business Stewardship 

The institutional/commercial/industrial (ICI) sector 

represents the largest land use surrounding airport 

lands. Given their prominence and the unique 

challenges they present to implementing site and 

lot-level stormwater control, spills abatement and 

habitat enhancement in valleylands, the ICI sector 

represents a key partner in the implementation of 

the recommendations of this report. The sector 

also represents a potential long-term steward 

of the watershed and a partner of TRCA in 

protecting, restoring and enhancing the health of 

the watershed. 

Lester B. Pearson International Airport is ISO 14001 

certified and has implemented various programs to 

improve its environmental performance, invested 

in state-of-the-art pollution abatement equipment 

and is committed to future environmental 

improvements in the watershed within the confines 

of its business operations. The intent is to expand 

GTAA’s leadership in environmental stewardship by 

encouraging businesses to adopt sustainable best 

management practices. 

Toronto and Region Conservation has initiated 

several business outreach programs across the 

Greater Toronto Area (GTA): the Frenchman’s Bay 

Project in Pickering, Langstaff EcoPark in Vaughan, 

West Toronto Business Environment Group and 

the Bartley Smith Greenway. Likewise, TRCA has 

35



Watershed 

worked with the following companies on numerous 

projects surrounding airport lands within the 

Etobicoke watershed: 

1 Pratt and Whitney Valleyland 

Restoration/wetland creation 

This project entailed the construction of a 

habitat wetland area within the floodplain 

of the Etobicoke Creek in order to capture 

seasonal overbank flow and provide for 

enhanced terrestrial/ephemeral aquatic 

habitat. It also includes the creation of four 

riparian forests. A partnership between 

Pratt & Whitney, TRCA and the City of 

Mississauga, it engaged the resources of 

all groups to enhance both aquatic and 

natural heritage habitat along the Etobicoke 

Creek. Pratt & Whitney also championed the 

West Etobicoke Creek Restoration Project 

currently underway in partnership with the 

City of Mississauga and City of Brampton. 

2 Daimler Chrysler Brampton Assembly 

Plant 

For four years TRCA has been a part of 

Daimler Chrysler’s Earth Day information 

symposium, providing information on the 

watershed, environmental giveaways and 

building a partnership for future projects. 

3 Canada Colours and Chemicals 

Toronto and Region Conservation worked 

with Canada Colours and Chemicals to 

install a kestrel box and to develop a 

naturalization plan for their valleylands. 

Pratt and Whitney Wetland 

36

The findings from these past projects provide a 

foundation for a Business Stewardship Program to 

aid in the implementation of the recommendations 

of this report. Those findings include: 

• The development of an in-house champion 

and volunteer base provides the foundation of 

building on individual successes through social 

marketing. 

• Short-term projects provide the best opportunity 

to build this relationship and educate through 

meaningful in-the-ground actions. 

• Through the development of small projects, a 

foundation of support can be built to develop 

larger projects with broader impacts. 

• Once projects have been completed it is 

important to promote the projects to the wider 

ICI community as a model for further action with 

new partners. 

From the experience of these partnerships, a 

foundation for future work has been set and the 

profile of watershed issues elevated within these 

organizations. These projects provide a base from 

which to develop a Business Stewardship Program 

to engage the ICI sector as watershed stewards. 

A complementary program already underway 

presents an opportunity for small- to mid-sized 

manufacturing companies within the GTA to 

implement pollution prevention (P2) planning 

and action. This program could be marketed 

aggressively in the GTAA study area to realize 

water quality goals set out in this report. As 

a partnership between the Toronto Region 

Sustainability Program and the Ontario Centre 

for Environmental Technology Advancement 

(OECTA), it allows manufacturing companies with 

fewer than 500 employees to have a pollution 

prevention assessment conducted by pre-qualified 

consultants that identify the root causes of priority 

pollutants and wastes, and recommend technology, 

processes and operating practice improvements for 

their facilities. 

Project Description and 

Recommendations 

Building partnerships between business and TRCA 

is an important piece in the inception, completion 

and stewardship of priority restoration sites within 

the watershed. While there is often a heavy focus on 

day-of events, such as plantings and clean-up days, 

there is a real need to engrain stewardship into the 

daily lives of both citizens and their employers. 

The emphasis of Business Stewardship Program 

is on the ICI sector as a community development 

partner and valued long-term steward with a 

mutual interest in environmental protection 

for improved profile, employee morale and 

community improvement. 

Goals: 

• To improve watershed practices of local 

industries both upstream and downstream of 

the GTAA. 

• To educate the ICI sector through meaningful 

in-the-ground actions. 

• To develop an eco-ICI sector around GTAA lands. 

Recommended approach: 

• Inventory potential business champions within 

the GTAA study area. 

• Develop relationships with businesses in 

order to: 

• Raise awareness of current best management 

practices. 

• Instigate a desire to change by demonstrating 

the benefits to the business by incorporating 

best management practices. 

• Pursue commitments to have business 

implement a small, manageable project. 

• Facilitate action by providing support to 

businesses who have made a commitment. 

• Evaluate actions by polling, documenting case 

studies, and the number of businesses that 

wish to continue with other projects and/or 

further planning. 

• Celebrate and replicate success by promoting 

accomplishments. 

37



Watershed 

• Create long-term champions of business best 

management practices. 

• Improve practices of the ICI sector in 

the watersheds. 

Recommended project types: 

• Improve Natural Heritage 

• Riparian plantings 

• Passive lawn naturalization and/or change in 

lawn management practices 

• Shade trees on south to cut air conditioning 

costs and evergreens on north to save on 

heating bills 

• Improve Stormwater Controls 

• Installing permeable pavement 

• Disconnecting downspouts/roof leaders 

• Create small swales and detention ponds 

• Establishing ponds with onsite storage 

• Installing oil/grit separators 

• Substitute salt-based de-icers with non-salt 

alternatives (calcium magnesium acetate, 

sodium formate or natural substances such as 

bird seed or sand) 

• Constructing roof-top gardens 

• Spills Abatement 

• Development of spills control plans (e.g., 

retrofit stormwater ponds, outfall oil/water 

separators, etc.) 

• Development or redevelopment of spill 

response systems 

• Education and Stewardship 

• Begin Earth Day program 

• Involve employees in clean-up days 

• Involve employees in watershed projects 

There are a number of regulatory, economic and 

suasive arguments for achieving sustainable 

development in the watershed, ranging from 

reducing environmental impacts and reducing 

costs, to improving public relations and the local 

community. But the strongest argument is that a 

healthy economy relies on a healthy environment 

– the two are inseparable and both function best 

when they are vibrant and diverse. 

Building valuable partnerships with the ICI sector 

offers the opportunity to build a sustainable 

economy soundly implanted with a healthy 

watershed. A complete list of Potential Business 

Stewards can be found in Appendix 3 and Business 

Stewardship Opportunities can be viewed

6.0 Monitoring and Measuring 

Progress 

The monitoring of projects plays an important role 

in dictating where funding should directed and 

whether or not proposed restoration strategies have 

been successful or should be altered. This report 

recommends two ways for monitoring success: 

• Sewershed Monitoring – Implementation in 

Focus Area 1: Catchment 219 should focus on 

measuring water quality within the catchment 

and as water leaves the catchment area. 

Monitoring on this scale will provide the needed 

feedback to address stormwater upgrades or 

whether or not the recommendations have 

been successful. 

• Regional Monitoring Network (RMN) – TRCA’s 

RMN monitors changes in habitat, terrestrial 

heritage and water quantity and quality 

throughout the watershed and provides a 

framework for monitoring changes over time. 

• Overall monitoring on the state of terrestrial 

natural heritage, aquatic system, water quality 

and quantity, and community stewardship 

is measured and reported on a regular 

basis through watershed report cards and 

Etobicoke and Mimico creeks watersheds Creek 

Time newsletter.

This site is a complex of upland and lowland forest types, with pockets of marsh and ash 

mineral swamp. Opportunity exists to increase the size and improve the shape of the existing 

forest patch to protect and maintain the vegetation communities and flora that are rare within 

the urban land matrix. Invasive plant species are problematic within the site (e.g., European 

buckthorn, purple loosestrife); therefore, invasive species management should be considered. 

Reforestation would create a significant patch of forest but given its isolation, recruitment of 

avifauna could be problematic unless the hydro corridor is restored with patches of forest or 

thicket to improve the connectivity to the main riparian corridor. 

This site, along with Sites 5, 6, 7, 8 and 9, fall within the hydro corridor. The area is complexed 

by various wetland communities, both native and exotic (purple loosestrife/reed canary grass 

mineral meadow marsh and narrow-leaved cattail mineral shallow marsh). Enhancements 

to these sites are limited by the constraints the overhead hydro wires impose; therefore, 

opportunities to promote wetland linkages, creation of swamp thicket habitat and invasive 

species management are the recommended activities for restoration and enhancement. Work 

here will contribute to overall biodiversity by increasing the amount and diversity of habitats 

and ameliorating lack of connectivity across a number of remaining patches of existing forest. 

See Site 4 details/rationale 




See Site 4 details/rationale. In addition, there appears to be a thriving community of meadow 

avifauna species in this location, which, to a degree, is compromised by the neighbouring 

residential area (i.e., informal trails and roving pets in sensitive areas). Measures to encourage 

growth of thicket habitat or strategically placed wetland habitat would go a long way to 

mitigate these impacts. 

This site is one of the few remaining patches of forest adjacent to the hydro corridor mentioned 

above. This patch is significant given the relative dominance of bur oak (Quercus macrocarpa) 

in the canopy (L4 species) and an inclusion of a white ash mineral deciduous swamp (a 

vegetation community of concern within the urban matrix, L4). Recommendation is to buffer 

this community against external negative impacts and enhance its size through planting 

of representative species. As in Site 3, the isolation of this patch from other natural areas is 

problematic for its decolonization by species of concern unless the hydro corridor is restored 

with patches of forest or thicket to improve connectivity with the main riparian corridor.

The area is currently an open meadow, likely mowed a few times a year. It lies adjacent to a 

mature dry-fresh sugar maple/oak deciduous forest (L4) community that hosts a suite of flora 

and fauna species of concern. Opportunity exists within this site to significantly increase the 

size of this forest patch and provide opportunity for area-sensitive species such as wood thrush 

(Hylocichla mustelina). 

Currently the site appears undeveloped and would represent an opportunity for reforestation 

that would significantly buffer and enhance patch size of the neighbouring forest. This existing 

forest is a fresh-moist oak/sugar maple deciduous forest, an L3 community, with an inclusion 

of a rare dry-fresh white pine/oak-mixed forest community (L2). Reforestation within this area 

would significantly benefit these vegetation communities and the suite of rare flora they shelter 

(including the jurisdictionally rare twinleaf ). 

There are several young woodlands here of sugar maple-oak and hickory. Both of these 

vegetation communities are very rare and sensitive, especially within the context of this study 

area. There are also many resident L3 and L4 flora and fauna within these young woodlands. The 

existing forest patch is extremely narrow, therefore exceedingly sensitive to external negative 

impacts. Recommendation here is to reforest adjacent lands to improve this community’s 

resiliency and to significantly increase patch size to benefit resident fauna. 

Within the site there are two vegetation communities of concern, a fresh-moist black walnut 

lowland deciduous forest (L3) and a narrow-leaved sedge mineral meadow marsh (L4). 

Recommendations for this site include size increases to the black walnut lowland forest and 

enhancements to wetland habitats within this block. 

Along with the black walnut forest mentioned in Site 14, this black walnut lowland deciduous 

forest is the only L3 community within the immediate airport vicinity. Restoration activities here 

would seek to improve both size and shape for this forest community via the reforestation of 

adjacent lands, where height restrictions at end of runway allow for this. If soil and topographic 

conditions allow, a wetland creation may be another possibility. 

There are several plantations here of ash, poplar and black walnut, with a silver maple 

understorey. There is also an adjacent reed canary grass mineral meadow marsh. Opportunities 

for restoration could include augmentation of the existing plantations, with further plantings 

of black walnut and ash. There is opportunity to also create silver maple swamp habitat, taking 

advantage of current topography and existing silver maple populations. Further work could 

also be undertaken to enhance the reed canary grass meadow marsh with plantings of native 

dogwoods and willow shrubs. 

Opportunities exist here to connect a willow mineral deciduous swamp populated by native 

peach leaf willow (Salix amygdaloides) (L4), with existing hedgerows containing another rare 

feature in the GTAA study area—mature trees. These hedgerows also contain another L4 species, 

bitternut hickory (Carya cordiformis). Infill plantings between and around these hedgerows, and 

riparian plantings around existing wetlands would significantly increase the functionality and 

size of this habitat patch, along with buffering and contributing to overall biodiversity on site. 

Restoration activities could encompass riparian plantings alongside the creek where several L3 

to L4 flora can be found bank side. Reforestation of marginal agricultural lands and plantings to 

improve patch size and shape are recommended. 

There are several forest communities existing in this park, black walnut lowland (L3), ash 

lowland (L5) and fresh-moist sugar maple hardwood (L5). The maple forest is a very mature 

community that supports numerous flora species of concern — a rare feature within the 

GTAA study area, north of Highway 401. Recommended restoration activities would include 

reforestation of the adjacent meadow to the north-west of this forest patch to optimize patch 

size and buffer against external negative impacts.

There is a small fresh-moist white cedar/hardwood-mixed forest (L4) in the extreme south-west 

corner of this site that supports several flora of concern. This community should be increased 

in size through reforestation efforts. Across the greater site there is large-scale opportunity 

to increase natural cover and to create a mosaic of habitat types. Where hydro corridor 

constraints occur, native shrub thicket and meadow would be the preferred habitat. North of 

the creek, beneath the hydro lines, the moisture regime is such that opportunities exist here 

to also establish wetland community types. Running west from Dixie Road are several reed 

canary grass mineral meadow marshes, complexed with narrow-leaved cattail mineral shallow 

marshes. The functionality and quality of these habitats would greatly be increased by any 

restoration activities that would see these communities buffered and enhanced by tree and 

shrub plantings. In the extreme northwest of the site, reforestation with upland forest species is 

possible. 

This site is best characterized as a complex of reed canary grass and narrow-leaved cattail 

mineral meadow marsh, with open aquatic (pond) habitat elements. Restoration activities 

recommended here would include promoting connectivity of remaining wetland pockets 

through plantings of suitable wetland shrubs, forbs and sedges. Additional restoration would 

include increasing the size of existing forest patches in the floodplain, and upland forest 

establishment on areas of higher topographical relief. 

This site contains many remnants of the historical forest that once dominated the lands adjacent 

to Etobicoke Creek. The area is populated by many L4 flora species of concern such as bur oak 

(Quercus macrocarpa) and bitternut hickory (Carya cordiformis). Recommendations for site 

restoration here include increasing the size of existing forest patches and improving overall 

patch shape through reforestation activities. By doing so, this area would represent a significant 

forest patch in the study area and would likely be large enough to support numerous species of 

concern. 

Within this site, adjacent to the creek are numerous willow shrub beach vegetation communities 

(L2), and broad-leaved cattail mineral meadow marshes (L4). Adjacent lands are largely 

thicket, cultural woodland, meadow and agriculture. Recommendations for this site include 

reforestation measures adjacent to the aforementioned sensitive vegetation communities 

through riparian plantings and reforestation to create new forested habitat, protect sensitive 

communities, and improve overall patch size and shape. Opportunities also exist to create 

wetland habitat within the hydro corridor to the southwest, in what is currently agricultural field 

(likely wet and marginally productive). 

This site is largely open meadow, with wet pockets and small swales. L3 and L4 flora are 

confined to aquatic habitat instream and bankside. Restoration opportunities here include 

riparian plantings to improve and protect sensitive aquatic habitats and prevent bank erosion. 

A large block of this site is isolated on three sides by Derry Road to the south, Etobicoke Creek 

to the west and a small creek to the north. There is an ideal opportunity within this area to 

create wetland habitat by modifying current topography and taking advantage of wet meadow 

conditions and the hydrophytic plant communities that are currently present.

HIP Description 

The Habitat Implementation Plan (HIP) is a targeted 

implementation strategy, rooted in watershed-wide 

habitat concepts, and prioritized according to site 

level criteria. In other words, the HIP will act as a 

mechanism by which the concepts of the Terrestrial 

Natural Heritage Program, Fisheries Management 

Plan, and Watershed Management Strategy, can 

be implemented. 

The HIP contains a catalogue/database of potential 

restoration sites which are linked to GIS information 

layers. The information stored within the database 

includes general site descriptions, existing habitat 

components, the potential habitat opportunities 

identified, and an implementation priority score. 

The HIP database of projects functions through 

a dynamic process based on querying data to 

determine the highest priority site for restoration. 

Etobicoke-Mimico Creek Watersheds 

Habitat Implementation Plan 

In 2003, the Etobicoke-Mimico HIP (EMHIP) was 

completed for TRCA properties and some adjacent 

areas. Priority areas were identified through this 

process and portions of the recommendations 

have been implemented in subsequent years. The 

areas identified in the GTAA Assessments were 

assessed and prioritized as an extension of the 

EMHIP. The priority results in this document are 

the result of a geographic query based on GTAA 

assessment locations. 

GTAA Assessments 

In February 2005, assessments were performed 

regarding selected areas surrounding the 

GTAA. Sites were selected based on Terrestrial 

Natural Heritage Target System ranking and 

Fish Management Plan priority areas. HIP field 

assessments identified current site conditions 

and potential for habitat improvements. Field 

assessment sheets and priority score sheets were 

completed on site for each area. All assessment 

forms have been entered into the HIP database and 

are linked to the GIS layers based on their site code. 

Map 7 indicates the areas that were given a priority 

ranking based on HIP assessments. Please note that 

the ranking is based on only the sites identified on 

the map, and does not reflect their overall ranking 

within the entire watersheds. Within this document, 

project backgrounders have been completed 

for the high priority areas identified. These 

backgrounders are preliminary only and should be 

subject to further planning and development upon 

project initiation.

Date Assessed for HIP: February 22, 2005 

Location: 

Site Description 

West Etobicoke, 

Brampton 

Kennedy Road and 

First Gulf Boulevard – 

See attached map 

Site Conditions: 

This site consists of two main areas, mostly 

floodplain on both sides of Etobicoke creek. The 

north side of the creek is mainly flat floodplain 

dominated by old-field species with steeper valley 

slopes toward the east and west ends of the site. 

These slopes and the northern section of the site 

are best characterized as deciduous woodlands 

with both cultural and native species. Recent 

plantings have occurred in the northwest section 

of the floodplain, as well as the northeast part of 

the site next to highway 410. A paved path runs 

the entire length of the site along the north side of 

Etobicoke creek. 

The south side of the creek has a steep valley slope 

that extends along most of the creek with some 

noticeable erosion occurring toward the middle 

of the site. The slopes have deciduous woodland 

communities including hawthorn, sugar mapleironwood 

and cultural species. This part of the site 

also includes a level plateau above the creek that is 

used as a sports park, which is dominated by exotic 

old-field meadow species. 

The river meanders through the site and includes 

sections of gabion fencing and armour stone, 

as well as a constructed berm and water control 

structure in the middle of the site on the north 

side. This has created a small flood pond that may 

also receive stormwater runoff from the adjacent 

industrial park.

Restoration Opportunities and 

Constraints 

Adjacent Land-Use(s): 

The north section is maintained for low intensity 

uses such as hiking, biking, and wildlife viewing, 

while the south side is used as a sports park with 

numerous playing fields and several buildings 

including the Brampton Safety Village. The 

Brampton Public Golf Course and a medium density 

residential area lie to the west, just upstream of 

the site. North of the site is an industrial park 

that is continuing to expand. East of the site, or 

downstream, are two major highways, the 410 and 

the 407, as well as a sewage treatment plant. 

Impacting Site Features: 

The large section of floodplain on the north side of 

the creek has dense ground cover vegetation and 

limited trees and shrubs likely due to the intense ice 

flows that the creek may experience. Although the 

soils in this section of the site may be quite fertile, 

restoration plans should consider the fluctuating 

water levels in the creek and the potential for ice 

damage as a limiting factor to planting this section 

of the site. 

On the south side of the creek, adjacent to the 

sports park restoration planting and/or seeding 

plans should include measures to control 

competition, including the use of both mulch 

mats and rodent guards. Mowing of the site prior 

to planting should help to make the planting 

process easier. 

Preliminary Restoration Concept Plan: 

This site is has two main vegetation communities: 

old field meadow dominated by exotic species 

such as golden rod and field grasses and deciduous 

woodlands with both native and exotic woody 

species. Portions of the creek corridor have steep 

slopes with obvious erosion and some sections 

of the creek on the north side lack riparian cover. 

A flood pond exists in the middle of the site 

on the north side of the creek. Therefore the 

objective of the restoration efforts are to increase 

the amount of riparian cover in site; expand the 

existing forest communities; and enhance existing 

vegetation communities. 

Riparian Planting: 

A 30m-wide buffer should be established 

along the creek to protect the banks 

from erosion, provide water quality 

improvements and protect fish habitat. Due 

to fluctuations in water levels in the river 

and the potential for ice damage during 

thawing periods, shrubs such as willows 

should be used in the flood plain area of the 

riparian zone instead of trees, as they will be 

more resilient to these conditions. 

Forest Expansion: 

The existing native deciduous woodlands 

including the sugar maple forest on the 

north and south sides of the site should be 

expanded. If site conditions are appropriate 

plantings could also include conifer thickets 

with eastern hemlock, as a small grove 

exists on the south side of the creek. Forest 

expansion would improve the habitat for 

forest dwelling wildlife including migratory 

bird species. Conifer thickets would increase 

the vegetation diversity of the site and 

therefore contribute to wildlife biodiversity. 

Tree and Shrub Nodes: 

Portions of the site are currently dominated 

by goldenrod and old-field grasses, 

therefore, this site has been identified for 

the establishment of tree and shrub nodes. 

Using site appropriate, native trees and 

shrubs will help to promote the natural 

succession of the site by providing a seed 

source for future plants, increasing the 

amount of forest cover in the area, and 

improving habitat opportunities for wildlife. 

This type of planting will also maintain 

the meadow component of the site. The 

types of species selected for the project 

should be tolerant of both wet and dry 

growing conditions, as the site will be 

prone to periodic flooding from the creek 

on the north side and will be subject to 

drier conditions on the south side. The 

49



Watershed 

south side of the creek, including sections 

of the Brampton Sports Park should also 

include the establishment of shade trees 

in appropriate areas around the playing 

fields and, if suitable, rows of buffer 

trees as natural fences and windbreaks. 

Furthermore, a wildflower meadow with 

educational interpretive signage would add 

another dimension to the sports park as an 

educational facility. 

Critical Wildlife Habitat (CWH) Structures: 

CWH structures such as raptor poles, bird 

boxes, brush and rock piles, and coarse 

woody debris should be included where 

appropriate throughout the site. The 

installation of these features on the site 

will enhance the wildlife value of the site 

by providing additional wildlife habitat 

opportunities for small mammals, birds, and 

amphibians. 

Potential Regulations and Approvals Required: 

• Archaeological Assessment (TRCA) 

• Flood and Fill Regulations (TRCA) 

• Ontario Ministry of Natural Resources 

• Municipal Agreement 

Potential Community Participation 

Opportunities: 

This project is well-suited to community 

involvement, and the public will be important in 

ensuring the success of the project over the longterm. 

Children from the local schools or community 

groups such as Scouting organizations should be 

considered as participants in the planting events. 

Some of the activities, such as site preparation will 

not be well-suited to community involvement, 

due to the heavy construction equipment 

required to complete the tasks. In addition, some 

reforestation planting may be more effectively 

carried out by TRCA staff using the tractor-mounted 

machine planter.

Site EMM 104 


Location: 


East Etobicoke, 

Brampton and

Bramalea Road and 

Highway 407 – 



The dominant feature of this large site are the two 

tributaries that run from west to east and meet in 

the middle of the site to form the east branch of 

Etobicoke creek. The westernmost sections of the 

creek are highly altered - they have straightened 

sections that employ velocity-slowing techniques 

such as bafflers and drop structures and have 

very little riparian cover. In both tributaries are 

sections of the riparian area with wet meadow 

characteristics, but the dominant vegetation 

community consists of old field species. 

East of highway 407 one section of the creek is 

forested with a deciduous vegetation community. 

Upstream of the confluence is an agricultural 

field, bordered by highway 407 and both creeks. 

Downstream of the confluence is a hydro corridor 

that runs roughly north-south but is still used for 

agriculture. Just north of the confluence is a willow 

shrub beach and a mineral marsh dominated by 

reed canary grass. As the creek enters another 

industrial area it is again altered with channelized 

sections and several drainage ditches that flow into 

the creek.

Bramalea Road. The core area of the site is bordered 

by agriculture fields and a large power grid and 

power supply station to the north. 


The creek is highly altered in some sections of the 

site and lacks riparian cover. Restoration plans 

that include plantings in the riparian zone should 

include measures to control competition, including 

both mulch mats and rodent guards on all plants. 

A hydro corridor runs north-south through the site 

and is currently used for agriculture. This includes 

an old-field section of the corridor with some wet 

meadow characteristics. 


The parts of the site that are not used for agriculture 

are dominated by old-field species such as 

goldenrod, teasel and field grasses, with a small 

section of wooded river valley. Therefore, the 

objective of the restoration efforts described here 

are to advance natural succession, increase wildlife 

habitat diversity, and provide riparian cover. 


Where possible a 30m-wide forested buffer 

should be established along the river to 

protect the banks from erosion, provide 

water quality improvements and protect fish 

habitat. Planting in this area will also extend 

the influence of the tree and shrub nodes 

towards the creek. Due to fluctuations in 

water levels in the river, and the potential 

for ice damage during thawing periods, 

shrubs such as willows should be used in 

some sections of this riparian zone instead 

of trees, as they will be more resilient to 

these conditions. Moreover a section of 

the creek falls within the hydro corridor so 

height appropriate species should be used. 

Forest: 

Portions of the area should be reforested 

with site appropriate species to provide a 

larger river valley corridor that will be more 

beneficial to wildlife. Additionally a forested 

strip should be planted along the edge of 

the hydro corridor to provide a buffer to the 

adjacent industrial area. 


Most of the site is currently used as 

agricultural land through the hydro 

corridor. However, should the fields be 

retired this site has been identified for the 

establishment of tree and shrub nodes 

suitable to a hydro corridor. Using site 

appropriate, native trees and shrubs will 

help to promote the natural succession 

of the site by providing a seed source 

for future plants, increase the amount 

of forest cover in the area, and improve 

habitat opportunities for wildlife. This 

type of planting will also maintain the 

meadow component of the site. The types 

of species selected for the project should 

meet the height restrictions for planting in 

hydro corridors. 

Wet Meadow and Wetland Enhancement: 

Some small sections of west of highway 407 

have been identified as having wet meadow 

characteristics. This habitat element should 

be emphasized and enhanced by increasing 

the vegetative diversity of the site through 

plantings. A larger section at the confluence 

of the creeks is also characterized as wet 

meadow. This area could be contoured 

down and designed as a flood pond 

wetland. The surrounding old field should 

also be enhanced with site appropriate 

shrub nodes and meadow species, as well 

as critical habitat features such as brush 

shelters and raptor poles. 


CWH structures such as raptor poles, bird 

boxes, brush and rock piles, and coarse 

woody debris should be included where 

appropriate throughout the site. The 

installation of these features on the site 

will enhance the wildlife value of the site 

by providing additional wildlife habitat 

opportunities for small mammals, birds, 

and amphibians.

Potential Community Participation Opportunities: 

This project is not well-suited to community 

involvement, as it is located in a highly industrial 

area, however local industries should be encouraged 

to participate. The site is highly visible from adjacent 

highways and roads therefore awareness can be 

raised through appropriate signage. 

Balmoral and Aloma Parks, 

Site EMM 105 


Location: 


East Etobicoke, 

Brampton 

Birchbank Road and 

Avondale Boulevard – 



This site consists of two tributaries of the east 

branch of Etobicoke creek that meet at the south 

end of the site. The creeks are part of two separate 

parks, Balmoral and Aloma, and have been highly 

altered. They have been straightened and lined with 

concrete and include several drop structures that 

also act as fish barriers. Although most of the parks 

are mowed, much of the stream banks have been 

left to naturalize, but they are almost completely 

lacking in riparian cover with the exception of the 

occasional non-native shrub thickets. In one area on 

the east tributary trees have recently been planted, 

however several were damaged or completely 

broken off possibly due to vandalism. Throughout 

the site are storm sewer outfalls that adversely 

affect the water quality of the creek.

centre, an arena and several sports fields. The south 

end of the site has more of an industrial character. 


The degree of alteration to the creeks, the 

straightened concrete channel and the multiple 

drop structures, as well as the storm sewer input 

and the lack of riparian cover have a negative 

impact not only on the site itself, but also to 

downstream areas. The arena is located directly 

beside the creek and the ice shavings likely also 

have adverse effects on the water quality. The 

industrial area to the south also affects the creek 

particularly near the confluence. 


This site represents a degraded creek system, 

therefore the objective of the restoration efforts are 

to increase the amount of riparian cover, provide bank 

stabilization and improve instream habitat features 

thereby increasing the value of the site to wildlife. 


The entire length of the creeks within 

the site should be buffered with riparian 

vegetation to provide habitat, shade, and 

bank stabilization. An increased amount of 

riparian cover will also improve the water 

quality of the creek by intercepting and 

filtering surface runoff. Species such as 

willows, dogwoods, silver maple, and white 

cedar would be well adapted to this area, 

and will enhance the habitat opportunities 

provided by the site. 


Two areas of the park have been identified as 

suitable for naturalization and the addition 

of tree and shrub nodes. Mowing of the 

areas should be restricted and a selection 

of site-appropriate, native trees and berryproducing 

shrubs should be planted in 

nodes to enhance the habitat features of the 

site by providing a future seed source and 

wildlife habitat, as well as contributing to 

the amount of riparian cover. 

Stream Rehabilitation: 

The creeks have been excessively altered, 

but the proximity to the residential areas 

and space restrictions limit extensive 

restoration of this site. Instead, efforts 

should focus on the creation of riffle-pool 

sequences and the removal of the concrete 

streambed where feasible. This will help 

to enhance the system as a more natural 

channel, improve the aquatic habitat of the 

creeks and lessen the impact of the altered 

creeks to downstream areas. 


CWH structures such as bird boxes, brush and 

rock piles, and coarse woody debris should 

be included where appropriate throughout 

the site. The installation of these features on 

the site will enhance the wildlife value of the 

site by providing additional wildlife habitat 

opportunities for small mammals, and birds.
