Name another major Canadian river that serves as northern transportation routes and has hydro potential.

• A. St. Lawrence River
• B. Ottawa River
• C. Mackenzie River
• D. Red River

Answer: (C)

Think about a river that stretches across Canada’s far north, acting as a key pathway to remote communities and also having enough flow to produce electricity. The Mackenzie River fits this well. It runs from Great Slave Lake across the Northwest Territories to the Arctic Ocean, forming one of the great northern waterways. Its vast length and network of tributaries made it, and still makes it, a primary route for moving people, goods, and information through the region, especially where roads are limited. The river’s large discharge and the geography of its basin give real potential for hydroelectric development along the river and its tributaries, which is a common reason people point to its importance. In contrast, the St. Lawrence and Ottawa rivers are major eastern waterways and aren’t considered northern transport corridors, and the Red River is a smaller prairie river with far less role in northern navigation or hydro power.
