St. Lawrence River

The St. Lawrence River stretches 1,197 kilometers northeast from Lake Ontario through Montreal and Quebec City to the Gulf of St. Lawrence.

French explorer Samuel de Champlain documented the river in 1604, establishing it as a primary route for early European settlement and trade networks.

The waterway connects multiple Indigenous territories and serves as a natural border between Canadian provinces and the United States, influencing regional traditions.

The St. Lawrence Seaway system enables ocean vessels to navigate directly from the Atlantic Ocean to Great Lakes ports through a series of locks.

The river supports North Atlantic right whales and features the Thousand Islands archipelago, containing over 1,800 individual land masses.
