Coteau-du-Lac National Historic Site
The Coteau-du-Lac National Historic Site is located about 50 km southwest of Montréal on the shores of the St. Lawrence River. It features Canada’s first lock canal and the remains of a fort.
With a history spanning 7,000 years, the site was a portage and encampment location used by Amerindians to avoid the rapids, a military fortification, and a canal that opened the way for commercial shipping.
