North West Company Lock

The North West Company Lock is located at the foot of Huron Street. It is actually two structures built almost 100 years apart. The stone replica lock seen today was built in 1896 and lies over the floor and framework of the original lock built in 1797. The lock was built to help laden canoes and boats navigate the rapids.
