The Trent-Severn Waterway is one of Ontario, Canada's most treasured waterways, offering boating enthusiasts a unique mix of natural beauty, history, and recreational opportunities. Spanning 386 kilometres from Lake Ontario to Georgian Bay, this historic canal system is a national historical site that is a must-visit destination for anyone who loves life on the water. Here’s what every boater needs to know about this iconic route that was recently named one of the best travel experiences of 2025 by the New York Times.
The Trent-Severn Waterway is a stunning network of interconnected rivers, lakes, and canals, making it a top-tier destination for recreational boating. Originally built in the 19th and early 20th centuries as a commercial shipping route, this historic lock system connects Trenton to Port Severn, winding through picturesque communities and gorgeous natural landscapes. It has since become a playground for boaters seeking adventure and relaxation.
Managed by Parks Canada, the Trent-Severn Waterway system features 44 locks, including two flight locks, two of the world’s tallest hydraulic lift locks, a marine railway, swing bridges, and heritage sites. It’s a remarkable combination of engineering brilliance and natural charm.
For boaters, the Trent-Severn Waterway offers a wealth of memorable experiences. Boaters can embark from marinas, communities, or remote access points along the waterway, all surrounded by breathtaking scenery. The waterway crosses nine different watersheds and passes through diverse landscapes, charming towns, and engineering marvels like the Peterborough Lift Lock and the Kirkfield Lift Lock, the world’s highest hydraulic lift locks. The Big Chute Marine Railway allows passengers to experience the thrill of being transported over land while on their boat—and it's the only marine railway of its kind in North America.
Boaters can enjoy activities such as fishing, waterfront dining, and exploring cultural sites and parks along the way. Trips can range from short day excursions to a full week-long (or more) journey to traverse the entire system. The waterway's tranquil environment and well-maintained facilities make it an ideal destination for both leisurely cruises and adventurous voyages.
Locks on the Trent-Severn Waterway are designed to raise or lower boats to navigate changes in water levels. A traditional lock allows watercraft to bypass rapids and waterfalls. Here’s how they operate:
Upstream Travel: Boats enter a lock chamber filled to the downstream water level. Once inside, the downstream gates close, and water is released from the upstream side to raise the boats.
Downstream Travel: The process is reversed, lowering boats to the downstream level.
For detailed guidance, check Parks Canada’s "Locking Through Safely" guide.
The waterway is located in Southern Ontario, Canada. It's easily accessible by car from Toronto's Pearson or Billy Bishop airports as well as Ottawa's International airport. Visitors from the U.S. can also easily drive to the locks from Buffalo, NY, Detriot MI, or Sault Ste. Marie MI.
