Dear Member,

This year we have consolidated and updated a lot of Winter Navigation related information to our webpage.   In lieu of creating a static Winter Navigation CL, we will endeavor to maintain this page taking into account the frequent number of changes during the transition to winter navigation in Eastern Canada.

Please visit the page to obtain information on:

  • Buoy Tending Schedules
  • Double pilotage and daylight restrictions for the St. Lawrence River, Great Lakes and Seaway
  • Transport Canada’s Cooling water recirculation requirements
  • Ice conditions
  • Coast Guard’s daily ice operations teleconference details
  • Status of the ice control zones
  • Recap of the Pre-Season Winter Navigation meeting
  • Information related to the closing of the St. Lawrence Seaway
  • Contact information for the Coast Guard ice operations centers
  • Status update for the Belle Isle Strait

To access the Winter Navigation page:

  • Login to the SFC Website
  • Click the Navigation tab from the top row
  • In the left-hand menu, select Winter Navigation 2021-2022

We would appreciate any feedback on this webpage and information provided.
