Canada is home to many significant rivers that play a crucial role in its geography and ecology. The longest river in Canada is the Mackenzie River, which flows through the Northwest Territories and empties into the Arctic Ocean. Other notable rivers include the St. Lawrence River, which connects the Great Lakes to the Atlantic Ocean, and the Fraser River, known for its salmon runs and stunning landscapes in British Columbia. These rivers are vital for transportation, recreation, and wildlife habitats. They support diverse ecosystems and provide resources for communities. Additionally, rivers like the Ottawa River and Saskatchewan River are important for agriculture and hydroelectric power generation, contributing to Canada's economy.
