Opened in 1849, the Saint-Ours Canal is a continuation of the Chambly
Canal, bypassing the final obstacle to navigation between the St. Lawrence
River and Lake Champlain.
Known as the tenth lock of the Richelieu, the Saint-Ours Canal is
situated between l'île Darvard and has been indispensable to international
trade for over a century.
Pleasure boating has replaced the canal's commercial traffic. Open
the gates of the lock and sail on the waters of the Richelieu River.
