The Study
The City of Toronto has initiated a Municipal Class Environmental Assessment (EA) study to implement a stormwater management facility and review alternatives for extending Legion Road in the vicinity of Bonar Creek. The Bonar Creek Stormwater Management Facility Project was identified in the 25-year implementation plan of the Wet Weather Flow Master Plan (WWFMP) in order to improve stormwater quality in Mimico Creek to provide an integrated work program for managing wet weather flow.

The extension of Legion Road is identified in the City's Official Plan. It will provide access to and from Lake Shore Boulevard West for existing and proposed development north of the CN Rail corridor and west of Mimico Creek; provide an alternative route for vehicles currently exiting the F. G. Gardiner Expressway at Park Lawn Road and destined to the Lake Shore Boulevard corridor; and, provide an alternative route for vehicles currently traveling eastbound on Lake Shore Boulevard and then northbound on Park Lawn Road.

Background

Bonar Creek Swm Facility
Bonar Creek is a branch of Mimico Creek. The creek discharges into Mimico Creek approximately 130 metres north of Lake Shore Boulevard West in the former City of Etobicoke. The Bonar Creek catchment is serviced by separate storm and sanitary sewer systems. The storm sewer catchment area branch to Bonar Creek is a mixture of residential, commercial, industrial, highway and open space areas.

The proposed stormwater management facility will be located on land that was historically marsh at the mouth of Mimico Creek and adjacent to Bonar Creek. The land is bounded by Harbourview Crescent/Legion Road to the west, Mimico Creek to the east, the CN Rail tracks to the north and Lake Shore Boulevard to the south. The northern portion of the land was once the Humber Sewage Dewatering Plant and has since been demolished. The southern portion of the land is currently vacant and was once used as a snow dump site.

Legion Road Extension
Legion Road is located in the south east portion of the former City of Etobicoke, west of Park Lawn Road and Mimico Creek. It is a two lane local road that extends north from Lake Shore Boulevard West to south of the former Humber Sewage Dewatering Plant.

The extension of Legion Road, from its northern limit to the Park Lawn Road exit ramp from the eastbound F.G. Gardiner Expressway, was identified in the City’s Official Plan. The issues identified to support the need of the extension include:

  • Satisfying the needs of the area;
  • Improving traffic safety; and
  • Improving the efficiency of the road network throughout the area

The Process
The study is being planned under Schedule C of the Municipal Class EA. The Class EA process includes public and agency consultation, an evaluation of alternative solutions and design concepts, assessment of the impacts of the proposed solution and identification of measures to mitigate any environmental impacts.

The purpose of the meeting was to introduce the study, explain the Environmental Assessment process, describe the alternatives that were evaluated and present the preferred solutions for both the Bonar Creek stormwater management controls as well as the extension of Legion Road. Comments are invited and requested by October 22, 2008. View the meeting material:

Public Open House #2
A public open house was held on Wednesday April 15, 2009 at Mimico Centennial Library to present the design options for the preferred solutions, learn about public feedback from the October 2008 public event and the next steps in the process. Comments are invited and requested by April 30, 2009. View the meeting material:
