Lockage and navigation
Saint-Ours Canal National Historic Site
Known as the tenth lock of the Richelieu and 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.
Because of fixed bridges and overhead power lines, vessels with masts exceeding 8 meters must unmast at Saint-Paul-de-l'Île-aux-Noix located upstream or at Sorel located downstream of the Saint-Ours Canal.
Float along the waters of the Saint-Ours Canal National Historic Site and enjoy the beauty of the Richelieu River!
Everyone knows Parks Canada’s waterways for the beauty of their surroundings and for the memorable and safe navigation experience that they offer. Did you know that an overnight stay there is also possible?
