The Sault Ste. Marie Canal is a National Historic Site in Sault Ste. Marie, Ontario, and is part of the national park system, managed by Parks Canada. It includes a lock to bypass the rapids on the St. Marys River. The first canal near the site was built in 1798, but was destroyed in 1814 during the War of 1812. The present canal dates to 1895, and formed part of the shipping route from the Atlantic Ocean to Lake Superior, along with the two locks on the US side of the river. One of the walls of the lock collapsed in 1987 and the canal was closed to traffic.
