Saint-Ours Canal National Historic Site


A sunset over Darvard island at the Saint-Ours canal

The Saint-Ours Canal lock enables boats to navigate a 1.5 metre difference in water levels. Put your kayak into the water and follow the banks of the Richelieu River.

Bring a picnic to the island and spend beautiful, relaxing hours in a unique, natural setting.

In order for different species of fish to be able to pass through the dam, a structure unlike anything else in the world was erected in the spring of 2001. It's a new experience for the whole family!
