As a result of the opening of the Saint-Ours Canal in 1849, boats could finally bypass the final obstacle on the waterway between Montreal and New York. For more than a century, the Saint-Ours Canal - called the 10th lock on the Richelieu River - has been indispensable to international, regional and local trade.

Today, the lock and its dam are a place of relaxation and fish observation - visitors will be intrigued by the Vianney-Legendre fishway, a one-of-a-kind device.
