The Lower Don Bridge and Don Yard early works will include:
- building a new bridge north of the existing rail bridge over the Lower Don River that will carry the Ontario Line tracks;
- shifting GO tracks in the Don Yard and nearby rail corridor to accommodate Ontario Line infrastructure;

Potential effects and mitigation measures
- Removal of/damage to trees, terrestrial vegetation and wildlife habitat.
- Impacts to aquatic/riparian vegetation.
- Erosion and sedimentation to waterbodies from construction.
- Disturbance or displacement of wildlife species and reduced habitat connectivity.
- Potential for impacts to fish and fish habitat.
- Risk of contamination to waterbodies as a result of spills.
- Introduction or spread of invasive species.
- Sensitive wildlife timing restrictions for early works activities (e.g., removal of vegetation outside of the breeding bird period).
- Tree/vegetation removals will be kept to a minimum and limited to within construction areas.
- Tree 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.
- Ensure that all in-water activities do not interfere with fish passage, constrict the channel width or reduce flows.
- Prior to early works activities, species-specific surveys will be completed to avoid or reduce potential impacts and meet all Species at Risk regulatory requirements.
