Coteau-du-Lac National Historic Site

The Coteau-du-Lac National Historic Site celebrates 100 years of historic designation in 2023. It 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 Indigenous to avoid the rapids, a military fortification, and a canal that opened the way for commercial shipping.
