Lockstation list and information

Trent-Severn Waterway National Historic Site

Every lockstation on the Trent-Severn Waterway forms part of a historic navigation system that connects Lake Ontario to Georgian Bay. Parks Canada maintains and operates these national historic sites to make travel possible for boaters and paddlers along 386 km of waterway. In addition to lockage and overnight mooring services, various other amenities at lockstations, such as washrooms, campsites and potable water, make it easy to plan a trip of any length. Each lock has its own story to tell and you will find friendly Parks Canada staff there to welcome you when you arrive.

The Trent-Severn Waterway National Historic Site 2026 navigation season will open in stages starting on Friday, May 15, 2026.

Increased precipitation in March and April, coupled with significant snowpack in both the Trent and Severn watersheds, has necessitated additional time to reduce water levels and flows to ensure safe boating conditions across the system.

Lock 42 - Couchiching to Lock 45 - Port Severn are closed to navigation until further notice. All lockstations will remain open to land-based visitation.
