Should Hydro-Québec Expand the Sainte-Marguerite-3 Dam Near Sept-Îles?
Official title: Adding Capacity to Sainte-Marguerite-3 Generating Station Project Public Notice Public Comments Invited on the Summary of the Initial Project Description
Why This Matters
Live on Quebec's North Shore? This project could affect the Sainte-Marguerite River and surrounding area. Indigenous communities have a direct stake in how this land and water are used. Even if you're far away, this decision shapes how Canada balances clean energy expansion with environmental protection.
What Could Change
If approved, Hydro-Québec could build a 300-metre underground pipe and install a third generating unit. The dam's total capacity would jump to 1,322 megawatts. Your comments now help determine whether a full federal impact assessment is required—or whether the project proceeds with less scrutiny.
Key Issues
- Should a full federal impact assessment be required for this expansion?
- What environmental concerns should be considered for the Sainte-Marguerite River?
