Notice of Determination

Ottawa, Ontario – June 18, 2024 – The National Capital Commission has determined that the proposed project is not likely to cause significant adverse environmental effects with the application of all recommended mitigation measures.

This determination was based on a consideration of the following factors:

• technically and economically feasible mitigation measures; and
• the components of the environment that are within the legislative authority of Parliament identified in the "Definitions" section of the Impact Assessment Act.

Mitigation measures will be implemented to address potential adverse effects on the following components of the environment:

• migratory birds
• groundwater
• surface water
• soil quality
• air quality
• vegetation
• human health
• archaeological resources

Some of the mitigation measures considered for this determination are:

• Implement a soil management plan by a qualified consultant to safely remove and dispose of contaminated soil following all federal or provincial regulations.
• Implement an Emergency Spill Response Plan to address spill containment and clean-up.
• Implement an erosion and sediment control plan to prevent natural movement of soils off the property.
• Implement a construction waste management program to reduce waste going to landfill.
• Conduct tree and vegetation removals outside of Environment Canada's bird nesting window on federal lands (April 8 to August 28) to prevent disturbance or harm to nesting birds and their young.
• Implement landscape plan after construction to compensation for tree removals.

After reviewing the comments received and conducting an internal review of effects, the National Capital Commission is satisfied that the implementation of the project is not likely to cause significant adverse environmental effects, as long as all mitigation measures are applied. Therefore, the National Capital Commission may carry out the project, exercise any power, perform any duty or function, or provide financial assistance to enable the project to be carried out in whole or in part.
