Opened in 1849, the Saint-Ours Canal and dam are the final section of the Chambly Canal, allowing boats to avoid the last hurdle between Lake Champlain and the St. Lawrence River. As the final link in the Richelieu Canal system, this canal was essential to the development of regional, national and international trade, which used this waterway for over a century.


Most of Canada's canals consist of a series of locks allowing boats to overcome obstacles such as dams, rapids, sandbars and rocky riverbeds.
