Exhibition Early Works Report
Published on Feb. 1, 2021
Ontario Line trains will be above ground at Exhibition Station, which currently accommodates GO Train and VIA rail services as well as freight rail operations. Since GO Expansion Plans call for more GO train services at Exhibition Station, Metrolinx is carrying out early works for the Ontario Line in this area to ensure both of these important transit expansion projects are properly coordinated and completed in a timely manner.
The Exhibition Station Early Works Report outlines the purpose of early upgrades at the existing Exhibition GO Station, including a description of local environmental conditions, potential impacts and proposed mitigation measures.

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).
