Dear Valued CN Customer,


To all Customers shipping Intermodal containers to/from the Province of Quebec, the Government has issued new end dates for Spring Thaw restrictions. While these dates posted by the Government of Quebec are subject to change, please note the updates below:

  • Spring thaw Zone 1: March 21st (00:01) to May 6th (23:59)
  • Spring thaw Zone 2: March 28th (00:01) to May 20th (23:59)

    • Spring Weight Restrictions map 2022

      Please note that payload weights in equipment to be delivered by CNTL must be reduced to meet the requirements in tables below for shipments planned to arrive after the start dates noted above.

      In the event of an overweight load, CN may arrange for transloading, or use specialty equipment to deliver the load. Any required transloading will be done at the prevailing market rate. Charges for use of quad chassis are per tariff CN-9100 Item 8560 ($800 per unit plus drayage fees). To ensure that specialty equipment is not detained, all deliveries must be live-unloads. Any overweight arrangements will be completed only after receiving written confirmation that the payer understands the charges.

       The maximum payload handled using CNR equipment during the Spring Weight Restriction period is:
