Natural Environment - Lakeshore East Joint Corridor

← Return to Early Works: Lakeshore East Joint Corridor

Key Findings

  • Vegetation is limited to narrow strips along the existing rail corridor, surrounded by commercial, industrial and residential areas, and neighbourhood parks.
  • The study area provides limited wildlife habitat with low connectivity to nearby natural features.
  • The study area does not feature any provincially or locally significant wetlands, areas of natural and scientific interest, woodlands or valleylands.
  • Species of Conservation Concern including Common Nighthawk, Eastern Wood-Pewee and Monarch; and Species at Risk including Barn Swallow, Chimney Swift and Bat Species at Risk may occur.
  • Isolated trees and shrubs, vegetation communities and buildings may provide nesting habitat for migratory birds.
  • During the early works activities, wildlife disruptions or displacement will be temporary and reduced via appropriate mitigation measures (see Potential Effects & Mitigation Measures). Following construction completion, disturbed areas will be restored.

Potential Effects & 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.
