Each fall, the arrival of colder weather brings back questions about winter tires and car insurance.
When are winter tires mandatory in Quebec? Which tires comply? Which rules come from regulations, and which come from the insurance policy?

Many drivers plan ahead and have their winter tires installed before the deadline. This helps them avoid last-minute appointments and prepare for the first winter conditions.

How to recognize compliant winter tires in Quebec

What to check every fall
A few checks each fall can prepare your vehicle for winter. They also help separate legal requirements from car insurance conditions.
- Schedule your winter tire installation
Book before the busiest period. This reduces the risk of delays when the first winter conditions arrive.
- Check whether your tires comply
Look for the three-peak mountain snowflake symbol. This marking generally confirms compliance with Quebec regulations.

- Inspect the overall condition of your tires
Check for wear, visible damage and adequate tread depth. An inspection can reveal issues before the snow arrives.
