Key Findings


  • Vegetation is limited to streetscapes (street trees, treed fence line or manicured lawns) and treed hedges (hedgerows).
  • The study area provides limited wildlife habitat given its urbanized nature.
  • The study area does not feature any provincially or locally significant wetlands, watercourses, areas of natural and scientific interest, woodlands, valleylands, environmentally significant areas or municipal or conservation authority policy areas.
  • Species at risk are not anticipated to be affected by construction activities.

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.

Mitigation Measures

  • Sensitive wildlife timing restrictions for construction activities (e.g., removal of vegetation outside of the breeding bird season).
  • Prior to construction, a Common Nighthawk (Species of Conservation Concern) candidate nesting habitat survey will be completed to confirm nesting habitat presence/absence at 1 Atlantic Avenue and, if habitat is found to be present, appropriate mitigation measures will be implemented (e.g., conducting building demolition outside of breeding bird window).
  • Tree/vegetation removals will be kept to a minimum and limited to within the construction footprint.
  • Tree removal compensation will be provided in accordance with the Metrolinx Vegetation Guideline (2020).
