Tips to Stay Compliant
To follow the Canada snow tire mandate by province, here are some simple ways to stay ahead:
-
Look for the 3PMSF symbol – The Three-Peak Mountain Snowflake marking ensures your tires meet winter safety standards.

FAQs
What qualifies as a snow tire under Canadian law?
A certified winter tire must have the Three-Peak Mountain Snowflake (3PMSF) symbol on its sidewall. All-season tires without this marking don’t meet Quebec’s winter driving law standards or BC’s highway safety rules.
Are snow tires mandatory in Ontario in 2025?
No, they’re not mandatory. However, snow tires are strongly recommended. Many Ontario insurance companies offer premium discounts if you install them before the tire deadline.
When do I need to remove my winter tires in Quebec?
You must remove them by March 15, 2025, in compliance with the Canada snow tire mandate by province.
Do I need winter tires on all four wheels?
Yes, it’s essential. Installing winter tires on just two wheels (especially only the drive wheels) can affect braking and steering. Four matching winter tires are both safer and legally required in some provinces.
Final Thoughts
Canadian winters demand serious preparation. By understanding the Canada snow tire mandate by province, installing snow tires before the tire deadline, and following your local winter driving law, you’re taking essential steps to protect yourself and others on the road.
