Thaw Period on Québec Roads

The thaw period for roads in Zone 1 and Zone 2 will begin on Monday, March 22, 2021.

The thaw period for roads in Zone 3 is expected to begin on Monday, March 29.

However, depending on changing weather conditions, this date may be brought forward or pushed back. For up-to-date information regarding thaw periods, visit the website of the Ministère des Transports.

During the thaw period, heavy vehicles travelling on the road network must make sure their loads comply with the thaw period load limits set under the Vehicle Load and Size Limits Regulation. In some cases, this will require reducing their loads.

These restrictions serve to limit damage to the road surface.
