Boating Guide Trent Severn Waterway: What Boaters Need to Know

One of the most unique waterways for boating in Canada is the Trent-Severn Waterway. Being 386 km long, this historical waterway links Lake Ontario to Georgian Bay via rivers, lakes, canals, and lockstations.

In terms of boating, this waterway offers a variety of attractions such as attractive waterways, historical towns, marinas, and other elements. But boating the Trent-Severn Waterway is not just putting the waterway into your GPS.

There are locks, bridges, water levels, navigation buoys, speed limiters, shoals, and many other aspects that have to be taken into consideration. This boating guide to the Trent Severn Waterway is meant to give you the information needed for a safe journey.

Understanding the Trent-Severn Waterway

The Trent-Severn Waterway extends across central Ontario, connecting Lake Ontario at Trenton to Georgian Bay at Port Severn.

During their travel on the route, boaters encounter many lakes and rivers and also go through lockstations. One unique feature is the Big Chute Marine Railway, which carries boats across the land between waterways.

As there are diverse waterways on the route, the conditions differ widely. What could be easy sailing in one stretch might require going through locks, bridges, narrow passages, and/or varying depths in another stretch.

Thus, you should plan your entire trip in advance.

Plan Your Trip in Advance

First, decide how much of the waterway you would like to travel on. Traveling through just one stretch is quite different from a longer trip between Lake Ontario and Georgian Bay.

During route planning, take into account such details as:

• Locks and timings
• Bridge clearances
• Depth of water
• Navigation aids
• Speed limits
• Fuel stops
• Mooring places
• Weather conditions
• Alternative routes

Parks Canada has all the navigational data on distances between locks, average lifts, dimensions of locks, bridge clearances, and other technical data.

Use a Good Nautical Chart

Having a detailed nautical chart is one of the key navigational instruments you need to have.

According to Parks Canada, you should use their visitor map only for reference purposes, not for navigation. Boaters are advised to use current nautical charts when navigating on the waterway.

A nautical chart can help you determine the following:

• Depth of water
• Water channels
• Reefs and shoals
• Navigational markers
• Bridges
• Location of the locks
• Hazards
• Anchorage areas
• Shoreline features

GPS Nautical Charts offers specialized marine charts for the Trent-Severn Waterway via its i-Boating Canada marine navigation app. It offers chart coverage for places such as Balsam Lake, Peterborough, Big Chute, Port Severn, and other lock sections. The app also has navigational features such as GPS navigation, route assistance, depth information, and other marine chartplotter capabilities.

Having access to a detailed nautical chart can help you navigate the waterway more easily.

Learn How the Locks Work

Lock passage is definitely one of the key experiences of boat trips along the Trent-Severn Waterway.

When getting ready for lock passage, slow down and follow the directions given by the lock operators and the signs that can be seen on site. After entering the chamber, your boat has to be tied up accordingly as the water level changes.

There is a guide provided by Parks Canada on lock passage procedures, from the approach to the exit of the lock chamber.

Leave more time for the lock passage in the course of your everyday schedule planning. The amount of traffic may influence the passage speed.

Besides, it would be useful to find out the lock hours and traveler information prior to the trip, not depend on the outdated schedule.

Pay Attention to Bridges and Clearances

The clearance under a bridge is one of those things that you should be aware of, especially for sailboats and cruisers.

Before heading to a bridge, check out the clearance at the bridge and see how tall your boat is. Water levels might make a difference in how high your clearance will be.

Do not assume that you can pass through just because you saw another boat of the same size pass by. Know how tall your boat is and how water levels affect the clearance.

Information on Parks Canada about navigation includes information on bridge clearance and technical information on the waterway.

Adhere to Speed Limits

There are speed limits and other restrictions on how you operate a boat in certain sections of the Trent-Severn Waterway.

According to Transport Canada’s current 2026 Vessel Operation Restriction Regulations schedules, there are certain sections of the Trent-Severn Waterway that have max speeds, with some of them having a 10 km/h speed limit.

Always adhere to the speed limits and no-wake areas. It is important to reduce your speed, especially near lock stations, bridges, docks, shorelines, and heavily recreational areas.

Check Weather and Waterway Conditions

Weather needs to be checked before departure and during the whole duration of the boat ride.

Wind, weather changes, storms, precipitation, and visibility can affect your route and experience while riding the boat. If the conditions do not favor the trip, you may think of halting in a safe place instead of adhering to your pre-planned time schedule.

Navigation is affected by the waterway conditions as well. Have a proper lookout and don’t depend completely on electronic navigation.

Mooring and Overnight Stopping Points

There are several places where one can halt their boat during the journey along the Trent-Severn Waterway.

According to Parks Canada, there is no prior reservation of mooring docks, as they are provided on a first-come, first-served basis. You will be responsible for your boat when docked.

If you are planning an overnight journey, plan the stops beforehand.

Important Safety Equipment

Prior to embarking on the trip, ensure that your boat has all the safety equipment necessary according to your boating activity and environment.

These may include the following:

• Life Jackets
• Navigation Equipment
• Communication Equipment
• Emergency Equipment
• First Aid Supplies
• Enough Fuel
• Drinking Water
• Navigation Maps
• Safety Lighting Equipment

All personnel aboard must know where the equipment is and how to use it during emergencies.

Parks Canada recommends being aware of the hazards surrounding dams, waste weirs, and strong currents.
