Locking through safely

The procedures and safety precautions to take when locking through are presented below.

Approaching a Canal

*At the Chambly canal, there is no wharf inside the lock. Lock operators will inform you of the side on which to moor and will give you mooring lines.

Into the lock

Note that it is the responsibility of pleasure craft operators to ensure that their vessels are properly docked and moored. Staff may provide assistance when you arrive, if they are available.

At the Saint-Ours, Lachine, Saint-Anne-de-Bellevue and Carillon canals, ensure that your craft is securely tied to the wharf. Tie up the back first by taking up all the slack, then tie up the front.

At the Chambly canal, do not attach mooring lines to your cleats. Loop the line around the cleat, making sure to lighten or loosen it during the lockage process.

Once your craft is well-moored, follow these instructions:

No Open Flasmes on Board No open flames on board
Turn Off the Engine Turn off the engine
No Smoking No smoking
Bilge Blower On Bilge blower on

Historic Canal regulations

It is the responsibility of pleasure boat operators to be informed of and familiar with the regulations in effect in historic canals. Certain activities are prohibited in a canal. Users must demonstrate judgment and civic-mindedness on Parks Canada sites at all times.

The following list of regulations is not exhaustive. In particular, you are not allowed to:

Historic Canals Regulations, Small Vessels Regulations and Collision Regulations are in force in all historic canals. These regulations are enforced by the Sûreté du Québec, the RCMP, municipal police, and their nautical units.

In the case of a repeated offence or refusal to obey the regulations in place, Parks Canada reserves the right to revoke, at any time, a permit or to forbid travel on the historic canals (section 6).

Speed limit on the canal

Speed Limit is 10 km/h

The maximum speed limit is 10 km/h (6 mph, 5.5 knots) while travelling through a canal. You must slow down when you reach the red and green buoys at the canal’s entrance; you can speed up after you pass the same-coloured buoys at the canal’s exit.

No wake

Wake limits must also be respected and take precedence over the speed limit. When you see a “no wake” sign, you must reduce your speed until your wake is completely eliminated.

The wake from boats causes major problems on Canada’s waterways:

Never forget that you are responsible for your wake and any damage it may cause.
