Additional information

  • Transit time: 30 minutes
  • Please arrive at least 60 minutes before the last lockage. The floating docks are located on starboard (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.
