In Quebec, winter tires are compulsory from Dec. 1 to March 15, and in British Columbia, many interior highways require tires to have at least an M+S rating for winter use.

That means it’s time for winter tires, and also the return of some of the myths about why they’re not necessary. If you use any of these for excuses, it’s time to think again.

It's mandatory in Quebec for all vehicles to have winter tires between Dec.1 and March 15. Some shops such as Garage Mécanique Galarneau in Gatineau, Que., have had to turn away some clients.
