Canada Winter Tire Law Updated for 2025 – Provinces Where It’s Now Mandatory

As temperatures drop and snow blankets the roads, winter tires become more than just a suggestion — they can be lifesavers. In 2025, Canada has updated its winter tire laws to further emphasize vehicle safety and reduce cold-weather road accidents. With the Canada Winter Tire Rules Update, several provinces have made winter tires mandatory by law during specific months.

Whether you’re a seasoned driver or a newcomer in Canada, here’s what you need to know about the latest Tire Law Canada update and which provinces are now enforcing these rules.

The Canada Winter Tire Rules Update for 2025 has been introduced to:

• Improve overall road vehicle safety

• Reduce traffic accidents during snow and ice events

• Make rules more consistent across provinces

• Raise awareness about the importance of winter tire use
