Story Routes — Waterways

Trent-Severn Waterway:
Trenton to Port Severn

A lock-by-lock guide to Ontario’s 386 km National Historic waterway — by boat, or visited town-by-town by car.

Created by Addison Mosseau, University of Toronto

About the waterway

The Trent-Severn Waterway is a 386 km National Historic Site managed by Parks Canada, linking Lake Ontario at Trenton to Georgian Bay at Port Severn through rivers, lakes, and canals. The system rises 180 metres above Lake Ontario — peaking at Balsam Lake — before descending 80 metres to Georgian Bay. Construction began in 1833 and the full route opened in 1920.

This guide is structured lock by lock, in cruising order. Many readers will never own a boat that fits the locks — so we’ve added 🚗 “Visiting by car?” notes at every town lock that works as a Toronto-area day trip. The Peterborough Lift Lock, the Big Chute Marine Railway, and the Kirkfield Lift Lock are particularly worth driving to.

How to use this guide

Stops are grouped into four regions matching the four distinct stretches of the waterway.

Each lock entry lists

  • the boat travel time from the previous lock (🛶),
  • the lockage time (⏱️),
  • a short description,
  • and eat/stay options.

Town locks and engineering highlights get expanded entries with Visit place links, Explore more references, and a car-traveller sidebar.

Open Water · Caution

Open Water: Lake Simcoe & Lake Couchiching Crossing

★ 5.0 📍 Gamebridge → Orillia, ON 🍴 No services until Orillia. Pack lunch and water for the crossing.

The trickiest stretch of the entire waterway. The route crosses the east arm of Lake Simcoe (30 km of open water), passes through the Atherley Narrows, and arrives at Lake Couchiching and Orillia. Check weather forecasts the night before — wind builds in the afternoon and the lake can be rough. Cross in the morning if possible. Full marine services, fuel, and provisions in Orillia.

Lock 43 Swift Rapids

One of the most unusual sights in Canada — even non-boaters travel here specifically to watch. · 🍴 Big Chute Marina for fuel and provisions.

There is nothing else like this in Canada — and only one or two like it in the world. Instead of a lock or lift, your boat is loaded onto a wheeled steel cradle and physically carried overland on rails — 18 m (58 ft) of elevation change, fully out of the water — between two stretches of the Severn River. It handles vessels up to 30.5 m long. The marine railway is the engineering showpiece of the whole journey. Watch from shore or ride in your boat — both are unforgettable.

🛶 Short transit through Orillia after the lake crossing·    ⏱️ ~20 min lockage time

End · Town · Georgian Bay

Lock 45 Port Severn — Journey’s End

★ 5.0 📍 175 Port Severn Rd N, Georgian Bay, ON 🚗 Visiting by car? Port Severn is ~1 hr 30 min from Toronto via Hwy 400. Park at Lock 45 viewing area, watch boats finish their journey. Combine with a short drive into the Thirty Thousand Islands of Georgian Bay (Honey Harbour) for a complete day. · 🍴 Rawley Resort for a celebratory dinner on the bay. Residence Inn Muskoka for a comfortable final night before heading home — or push on into Georgian Bay if you’re continuing.

The final lock. Pass through and the Severn River opens into Georgian Bay — sky, open water, Canadian Shield islands. You’ve completed 386 km, 44 locks, and one of Canada’s great waterway journeys. Lock 45 is also the smallest lock on the system (84 ft × 23 ft) and sets the upper size limit for any vessel attempting the full transit.

Good to know

Season & permits

Waterway operates Victoria Day (mid-May) to Thanksgiving Monday (mid-October). Parks Canada lockage permits are required and can be bought online at parks.canada.ca, at the first lockstation, or at Parks Canada visitor centres. Day, six-day, and seasonal permits are available; the seasonal permit pays off if you plan to lock through more than ~10 times. Mooring permits are separate and are required for overnight tie-ups.

Fuel & food

Fuel docks at Trenton, Campbellford, Peterborough, Bobcaygeon, Lindsay, Orillia, and Big Chute. Provision in the same towns — gaps of 30–60 km of pure transit are common between them. Long stretches without service: Frankford to Campbellford, Hastings to Peterborough, Young’s Point to Bobcaygeon, and Gamebridge to Orillia.

Vessel size limits

Standard locks: 36.6 m × 9.75 m (120 ft × 32 ft). Big Chute Marine Railway: 30.5 m × 7.3 m × 90 tonnes (100 ft × 24 ft). Lock 45 (Port Severn): 25.6 m × 7.0 m (84 ft × 23 ft) — the smallest lock and the binding constraint for any full transit. Depth: locks 1–19 carry 2.4 m (8 ft); locks 20–45 carry 1.8 m (6 ft).

Marine safety

Monitor VHF Ch. 16. Many lockmasters communicate on Ch. 68. The Lake Simcoe / Lake Couchiching open-water crossing (Lock 41 to Lock 42) is the trickiest stretch — 30 km of open water where wind builds in afternoon. Cross in the morning, check the marine forecast the night before, and stay close to the south shore if conditions deteriorate. Wildlife protection closures may apply near the Bay of Quinte in spring — confirm with Parks Canada before departure.

Visiting by car instead of boat

The best stops for road travellers are the engineering wonders (Peterborough Lift Lock, Kirkfield Lift Lock, Big Chute Marine Railway) and the town locks (Trenton, Campbellford, Hastings, Lakefield, Bobcaygeon, Fenelon Falls, Orillia, Port Severn). Each has a 🚗 sidebar in the relevant lock entry above. All have free or low-cost parking at the Parks Canada lockstation. Watching a lock cycle from a viewing platform takes 20–30 minutes; combine 2–3 town locks for a full day trip from Toronto.
