Spring Thaw 2021

Dear Customer,

 

Please be advised that the 2021 spring thaw season is quickly approaching.

 

We would like to take this opportunity to kindly remind customers shipping into the province of Quebec that the authorized load limits will be reduced during the thaw period.

 

The Ministry of Transport - Quebec implements these restrictions each year to account for the road network’s lower bearing capacity during this time.

 

Following are the predicted starting dates of the load restriction period for each of the thaw zones:

 

Predicted starting dates for 2021

Zone 1

  • From Monday, March 8 (00:01) to Friday, May 7 (23:59)

Zone 2

  • From Monday, March 15 (00:01) to Friday, May 14 (23:59)

Zone 3

  • From Monday, March 22 (00: 01) to Friday, May 21 (23:59)

 

Depending on changes in weather conditions, the start and end of the load restriction period can be moved ahead or postponed.

 

In response to the Ministry advisory, CN has released the following guidelines for the 2021 thaw season.
