The Township of Georgian Bay is home to two Trent-Severn Waterway lockstations. This National Historic Site navigates 386 km of heritage canals and locks, connecting Lake Ontario and Lake Huron.

Lock 44 – Big Chute Marine Railway

Big Chute Marine Railway, located at Lock 44, is the only marine railway of its kind in North America. Watch from the observation deck as skilled staff scramble up and down ladders to operate the slings and carriage that lift boats nearly 60 feet over a ridge between the Severn River and Gloucester Pool, then slips them gently back into the water on the other side. The original carriage built in 1917 has since been enlarged to carry boats up to 100 feet long.

Lock 45 – Welcome Centre

Depending on the direction from which you are approaching, Lock 45 in Port Severn is the last or first lock on the Trent-Severn Waterway. Before entering the Trent-Severn Waterway at Lock 45 in Port Severn, learn all about it at the Welcome Centre. Stop by during lock hours for a self-guided tour.
