Trent–Severn Waterway National Historic Site Advances Toward Full Navigation Opening

May 28, 2026

Parks Canada continues to work diligently toward reopening the entire navigation system and is maximizing water flows where possible to move toward seasonal averages. While water levels and flows remain dynamic across the system, Parks Canada anticipates a full opening on Friday, May 29, 2026, subject to weather systems and precipitation events.
 
The safety of our visitors and staff remains of the utmost importance to Parks Canada. Boaters, paddlers, and swimmers are reminded that certain areas continue to have higher-than-average flows and are asked to exercise caution. Floating debris may be present, and navigation aids may be off station as we continue to monitor and prepare the navigation channels. Waterways between or adjacent to closed lockstations should be considered unsafe for navigation.
 
Please see the table (below) for the most recent description of lockstations that will be open for navigation as of Thursday, May 21, 2026. This list will be updated and released via our website and social media channels daily until all lockstations are fully open. All lockstations will remain open to land-based visitation.

For more information about the Trent-Severn Waterway National Historic Site, visit our website or follow us on social media @TrentSevernNHS.

Until now, there hasn’t been an electric boat that really makes a statement. Enter the ENVGO NV1.

Canada’s Superior: the North Shore

Story and photos by Jennifer M. Smith

We’d been north before on a short two-week cruise. At the time, we were unprepared for the isolation, the lack of cell phone coverage, and the spotty VHF reception. Since then we’ve repowered, installed Starlink, and retired from work. Now, with confidence in our engine and our connectivity and more time to sail, we were Superior-ready.
