Trent-Severn Waterway NHS

"Salute human ingenuity as you travel this 386km waterway, first opened in 1922 to connect Lake Ontario and Georgian Bay. Today Parks Canada maintains and operates this historic lock system as a perennial destination for recreational boaters and paddlers, and a home to the many people who live, work, and play along its length."
