Recreational Boating

Lockage Schedule

Lockages are scheduled between the hours of 07:00 and 19:00 from June 15 to September 15. Outside of this interval, pleasure craft lockages will be performed on a “best efforts” basis given the schedule of commercial vessels (which have priority).


Lockage information is updated twice daily, at approximately 7:30 and 13:00.

The time specified reflects the earliest point at which service may be provided.  Service may be provided at any point within the hour following the time indicated. Please crafts should be at the lock at the indicated time to ensure that they are eligible to be serviced within the one hour period.

This information is provided on a “best efforts” basis only, and we cannot guarantee the accuracy of the information. Changes in traffic patterns or unforeseen incidents may trigger changes or delays in the posted schedule.

The same information on lockage times is available via audio recording at 450-672-4110 extension 2235.
