Lakeshore East Joint Corridor Early Works Report

Published on Nov. 17, 2021

Lakeshore East Joint Corridor early works will set the groundwork for other major construction on the Ontario Line and GO Expansion projects, reducing risk of construction delays to the main public-private partnership (P3) contracts by completing the Ontario Line and GO Expansion joint corridor work in advance of the main contracts for both of these transit projects.

The Lakeshore East Joint Corridor Early Works Report outlines the purpose of early works in and around the existing rail corridor in Riverside and Leslieville, including a description of local environmental conditions, potential impacts and proposed mitigation measures, and a record of consultation.

Potential effects and mitigation measures

Potential effects:

  • Disturbance or displacement of wildlife.
  • Removal of/damage to trees, terrestrial vegetation and wildlife habitat, including migratory breeding bird habitat.
  • Erosion and sedimentation

Mitigation measures:

  • Identify opportunities to promote pollinator species and habitat in accordance with the Metrolinx Vegetation Guideline (2020) (e.g., this may include planting or seeding native flowering plants in temporarily disturbed areas).
  • Tree and vegetation removal will be kept to a minimum and limited to within the construction footprint.
  • Tree and vegetation removal compensation will be provided in accordance with the Metrolinx Vegetation Guideline (2020).
  • Temporarily disturbed areas will be restored/re-vegetated.
  • Erosion and sediment control measures will be implemented.
  • Prior to early works activities, species-specific surveys will be completed to avoid or minimize potential impacts and meet all Species at Risk regulatory requirements.
  • Tree Protection Zones will be clearly staked prior to construction using barriers in accordance with local by-law requirements.
