To comply with the mandated requirements and avoid a backlog of loads requiring special handling, we will implement Spring Weight Restrictions in advance of the Quebec Government notice.
For customers shipping to and from the province of Quebec, Bison will be implementing reduced weight requirements as outlined below in Tables 1 & 2.
*As a reminder – some shipments may have Eastern Ontario destinations, (Cornwall, Ottawa, etc.), but are serviced through the Lachine Terminal and will be required to adhere to these guidelines.
For rail into NB restrictions are based on Zone limits and loads should be vetted by Intermodal prior to commitment.
The annual start date for cargo weight restriction is still only ‘Predicted’, currently estimated for March 17th, and is regulated by the Quebec Provincial government. The timing is dependent on several factors with the intention of minimizing damage to Provincial roads. Our plan is to have all loads exceeding the thaw period weight limits arrive/depart Quebec before March 17.
Should the Province mandate an earlier start date adjustments will be communicated. All loads exceeding the prescribed thaw period weight limits will be subject to special handling charges.
