Winter Tires in Québec 2026: Law, Dates and Buyer's Guide
Short answer: in Québec, winter tires are mandatory from December 1 to March 15 on passenger vehicles registered in the province. The tires must carry the three-peak mountain snowflake (3PMSF) symbol or be studded. An "M+S" marking on its own does not qualify. The fine is $200 to $300, plus costs.

3PMSF vs M+S: which marking counts?
Look on the sidewall for a small mountain with a snowflake inside it. That is the 3PMSF symbol, and it is what the law asks for. "M+S" (mud and snow) is a manufacturer's self-declaration about tread design, not a winter performance test. Many all-season tires carry M+S only, and they do not meet the Québec requirement.
Some all-weather tires do carry the 3PMSF symbol and therefore qualify. Always check the product page or the sidewall rather than assuming from the name. Our how to choose winter tires guide covers the symbol in more detail.
Two all-weather lines we sell are covered in our Fortune Climaflex 4S and Tercelo Croseason 4S guides. Each explains where its 3PMSF information comes from, and why you should confirm the symbol for your size.
Studded vs studless winter tires
- Studless winter tires use a soft compound and dense siping for grip on snow, slush and cold pavement. They are quieter, and they are the right choice for most city and highway driving.
- Studded winter tires add metal studs that bite into ice. They help most on icy rural roads and in freezing-rain conditions. They are louder on dry pavement and are only legal from October 15 to May 1.
- Studdable tires are built with stud holes so studs can be installed later. A studdable tire without studs is still a studless winter tire.
If most of your driving is plowed and salted roads, studless is the practical pick. If you regularly drive on glare ice, studs are worth considering.
Getting the size right
- Check the tire placard on the driver's door jamb or your owner's manual for the factory size, for example 225/65R17.
- Buy all four tires in the same size and the same model. Mixing tires on one vehicle affects handling.
- If you want a separate winter set on its own wheels, many drivers choose a smaller wheel diameter with a taller sidewall. See downsizing winter wheels and our steel wheels for winter guide.
- If your vehicle has a tire pressure monitoring system, a separate set of wheels needs its own sensors. See the TPMS guide.
Not sure how to read a size? Use how to read tire specs. Sizes shoppers search for often on our site include 225/65R17 and 215/55R17; you can browse every size from the winter tire page.
When to install winter tires
The law sets the date you must be compliant, not the date to install. Shops get busy in November, so book early. A common rule of thumb is to switch once daily temperatures stay around 7°C, because the winter compound grips better than an all-season in the cold. Remove them in spring once temperatures are consistently above that. Our spring changeover checklist walks through it.
