Luskville, Quebec – June 3, 2025 – 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: 

• Effects of land use changes; 

• 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; 
• species at risk; 
• biodiversity; 
• soil quality; 
• air quality; 
• vegetation; and
• human health and wellbeing

Some of the mitigation measures considered for this determination are: 

• Implement an erosion and sediment control plan to stabilize disturbed areas and prevent erosion into water bodies. 

• Implement a soil management plan by a qualified consultant to safely remove and dispose of contaminated soil following all federal or provincial regulations.  

• Clean all heavy equipment and ensure free of invasive species prior to accessing federal lands to prevent the spread and introduction of invasive species. 

• 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. 

• Isolate the staging area to prevent wildlife from entering. 

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.
