Major Canadian Cities Along the St. Lawrence River

The St. Lawrence River has shaped the development of several key Quebec cities:

• Quebec City – Provincial capital, oldest city in Canada, on the north shore ~400 km northeast of Montreal. UNESCO heritage site with historic architecture.
• Montreal – Largest city in Quebec, second-largest in Canada, on islands in the river ~290 km southwest of Quebec City. Major economic, cultural, and educational hub.
• Trois-Rivières – North shore, ~140 km northeast of Montreal. Industrial and port center with historic charm.
• Sorel-Tracy – South shore, ~70 km northeast of Montreal. Industrial city with heritage architecture.

These cities illustrate the river's enduring role as a corridor for settlement, trade, and culture.
