Question: Which river flows through Montreal and forms a key trade route?

Answer options:

• Fraser ✅ St. Lawrence
• Mackenzie
• Saskatchewan

Correct answer: St. Lawrence

Explanation: The St. Lawrence River is the correct answer because it flows directly past Montreal, connecting the Great Lakes with the Atlantic Ocean and serving as a vital historic and modern trade corridor. In contrast, the Fraser River is located in British Columbia, the Mackenzie River is in the Northwest Territories, and the Saskatchewan River runs through the Prairies, meaning none of them flow through Quebec. According to the Discover Canada guide, the St. Lawrence River is a defining geographic feature of Central Canada. Candidates should expect exam questions testing basic regional geography, including major rivers, cities, and their economic significance to Canadian history.
