Additional informations

  • Transit time: 30 minutes
  • Please arrive at least 1 hour before the last lockage. The last lockage is in up-stream to downstream direction. The dock located in the lock is on the port side (island side).
  • Please take note that times of first and last lockages are not guaranteed. To maximize chances of being locked through, arrive early enough to allow complete lockages in both directions.

Transport Canada's physical distancing standards for Canadian boaters must be respected. It is possible that boat capacity may be considerably reduced, and that the waiting time may be increased. We appreciate your patience and collaboration.
