NOTICE OF DETERMINATION

Vancouver, B.C. – July 31, 2025 – Transport Canada has determined that the proposed Shoreline adaptation and restoration - Tsleil-Waututh Nation Reserve project is not likely to cause significant adverse environmental effects.

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

• impacts on rights of Indigenous peoples;
• Indigenous knowledge;
• community knowledge;
• comments received from the public; and
• technically and economically feasible mitigation measures.

Mitigation measures taken into account for this determination are:

• The works will not deposit a deleterious substance in water inhabited by fish, or affect fish or fish habitat in a manner contrary to the Fisheries Act
• All works will be carried out in accordance with the Construction Environmental Management Plan
• A qualified environmental professional will be retained to monitor works and activities with the potential to negatively affect fish or fish habitat
• There will be no in-water work during the fisheries sensitive period from March 1 to August 15, inclusive
• All construction debris and waste materials will be collected in the immediate working area and disposed of at an appropriately licensed facility
• A spill prevention, containment and clean-up plan will be developed for the project, be available in the immediate working area, and project personnel will be trained on spill prevention, containment, and clean-up
• All construction equipment will be environmentally clean and properly maintained to prevent spills, invasive species, and noxious weeds
• Soils and other materials brought to the site will be clean and free of environmental contamination, invasive species, and noxious weeds.

Transport Canada is satisfied that that the carrying out of the project is not likely to cause significant adverse environmental effects.

Therefore, Transport Canada 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.
