Temporary Lock Closure

Sault Ste. Marie Canal National Historic Site

The Sault Ste. Marie Canal, built in 1895, was the world’s longest lock, the first to operate using electricity and the last link in an all-Canadian navigational chain from the Atlantic Ocean to Lake Superior. Today, the Canal is a great spot for boat-watching, picnics and a variety of other activities. Let a Parks Canada interpreter introduce you to the canal’s fascinating history, rent a Fat Bike, or join us for tea at the Superintendent’s Residence.
