Know the legal window
Québec requires winter tires during that period for covered Québec-registered motor vehicles, subject to the official rule and any exceptions. Plan installation before December 1 rather than waiting for the first storm. The date is a legal deadline, not a guarantee that November roads will be warm or dry.
Choose spring changeover by conditions
After March 15, the legal period ends, but snow and freezing conditions can still occur. Check the forecast, roads and the tires you plan to install before switching to summer tires. For the next winter, book early if your installer becomes busy. Verify any rule changes on Québec's official website.
A practical calendar plan
Book the autumn appointment ahead of December 1 and inspect the winter set before installation. In spring, treat March 15 as the end of the legal period, then look at the forecast and roads before changing tires. A ski trip to a colder area may call for keeping winter tires longer.
Quick check
- Install before December 1
- Keep winter tires through March 15
- Check conditions before spring change
