Which two rivers are recognized as major Canadian rivers for shipping/hydroelectric power and northern transportation?

• A. St. Lawrence River and Fraser River
• B. St. Lawrence River and Mackenzie River
• C. Mackenzie River and Nelson River
• D. St. John River and Yukon River

Answer: (B)

The question is about which rivers are most recognized in Canada for supporting large-scale shipping and hydroelectric power, as well as for northern transportation. The St. Lawrence River is the classic shipping artery, linking the Great Lakes to the Atlantic Ocean via the St. Lawrence Seaway, which lets ocean-going vessels reach inland ports and move vast amounts of goods. At the same time, rivers in its basin contribute to electricity generation in eastern Canada, making it a major site for hydroelectric power. The Mackenzie River runs through the northern part of the country to the Arctic Ocean and is a key route for northern transportation, a long-standing corridor for moving people and supplies in Canada’s north, with significant potential for hydroelectric development as well. Together, these two rivers embody both the shipping/hydroelectric role and the northern transportation role.
