Corktown Early Works Report
Published on July 15, 2021
Ontario Line trains will be below ground at Corktown Station, which will require tunnel boring through the future corridor. The Corktown Station site has been identified as the launch site for the tunnel excavation equipment to complete tunnels and underground station spaces for the downtown and Don Yard segments and construction of the Corktown Station.
The Corktown Station Early Works Report outlines the purpose of early works, a description of local environmental conditions, potential impacts, proposed mitigation measures and a record of consultation.

Potential effects and mitigation measures
Potential effects:
- Potential removal of/damage to street trees and urban wildlife habitat, including migratory breeding birds.
- Disturbance or displacement of urban wildlife within the study area.
Mitigation measures:
- Sensitive wildlife timing restrictions for early works activities (e.g., removal of vegetation outside of the breeding bird period).
- Prior to early works activities, a Common Nighthawk (Species of Conservation Concern) candidate nesting habitat survey and nest search for migratory breeding birds will be completed to confirm nesting habitat presence/absence on buildings within the project footprint and, if habitat is found to be present, appropriate mitigation measures will be implemented (e.g., conducting building demolition outside of the breeding bird period).
- Tree/vegetation removals will be kept to a minimum and limited to within the project footprint.
- Tree removal compensation will be provided in accordance with the Metrolinx Vegetation Guideline (2020).
