The Soulanges Canal is an abandoned shipping canal in Quebec, Canada. It follows the north shore of the Saint Lawrence River between Pointe-des-Cascades and Coteaux-Landing, bypassing the rapids between Lake Saint-Louis and Lake Saint-Francis. In between, it passes through the towns of Les Cèdres and Coteau-du-Lac. It superseded the first Beauharnois Canal which was on the south shore of the Saint Lawrence. It is 23 kilometers (14 mi) long and had a 4.3-meter (14.1 ft) draught. Five locks measuring 85.3 m × 14 m (279.9 ft × 45.9 ft) give a total rise of 25 meters (82 ft).
