Dease Strait is a significant tidal strait separating Victoria Island from the mainland of Nunavut, Canada. It forms part of the Kitikmeot Sea estuary and serves as a major waterway within the Arctic Ocean's Northwest Passage. The currents flowing through the strait concentrate baitfish, creating productive marine fishing grounds. The surrounding polar semi-desert landscape features willow-sedge meadows and dryas vegetation, with the strait ultimately connecting to the Arctic Ocean. Cambridge Bay (Iqaluktuttiaq), situated on Victoria Island's southeast coast between Dease Strait and Queen Maud Gulf, is the primary regional hub and a traditional hunting and fishing location, historically known as a "good fishing place."
