Notice of Determination

Ottawa, Ontario – June 13, 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:

• impacts on rights of Indigenous peoples;
• Indigenous knowledge;
• community knowledge;
• 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:

• air quality;
• human health; and
• historical resourcs

Some of the mitigation measures considered for this determination are:

• Implement spills response and action plan.
• Implement temporary pathway detour and ensure it remains open and accessible to the public at all times during construction.
• Ensure appropriate pedestrian control measures including construction signage is implemented and visible at all times.
• Upon completion of construction, all disturbed areas must be reinstated to existing condition or better.

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.
