James Bay Is Entirely in Quebec—Not Between Quebec and Ontario

James Bay is a large southeastern extension of Hudson Bay, located entirely within the province of Quebec, Canada.

• It does not border Ontario.
• The Harricana, Nottaway, Broadback, Rupert, and Eastmain Rivers drain into it.
• Major hydroelectric projects (La Grande Complex) are on its eastern rivers.
• Coastal communities: Chisasibi, Wemindji, Eastmain, Waskaganish (Cree Nations).

The Ontario-Quebec border runs north-south well west of James Bay. The bay's western shore is the Quebec coast; Ontario's northern coast is on Hudson Bay proper.
