Rehabilitation work of Utshimauat Petashu and Manitou Streets

Notice of determination

October 21, 2026 – Indigenous Services Canada has determined that the proposed Rehabilitation Work of Utshimauat Petashu and Manitou Streets 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 water collection structure planned for the wetland located between the municipal garage and the business center is designed to maintain the hydrological regime and ensure the preservation of the wetland's ecological functions after construction. The main ecological functions to be preserved are: surface water collection, stormwater retention, water filtration, and sediment retention (pollution filter) (Englobe 2025);

-During construction, implement effective measures to limit the transport of sediment into the aquatic environment and ensure their maintenance. These measures must remain effective during periods of high water, heavy rain, or freezing conditions;

-To prevent suspended solids and contaminants from being discharged into the St. Lawrence River via untreated stormwater, streets will be cleaned, waste materials will be managed, and storm drains will be maintained;

-The construction schedule will be communicated to the public in advance, and a communication channel for handling complaints will be established.

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

Therefore, the authority 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.
