Winter Tires 2026: When Are They Mandatory in Quebec and B.C.?

In Quebec, winter tires are mandatory from Tuesday 1 December 2026 to Monday 15 March 2027, inclusive, on cars and most other vehicles registered in the province; the fine is $200 to $300 plus costs. In British Columbia, winter tires (or chains, depending on the sign) have been required on signed highways since 1 October 2026, and on most of them that runs to 30 April 2027.

Other provinces do not have a blanket winter tire law, but the official advice everywhere is the same: put them on before you need them, not on the deadline.

This is general information from the SAAQ, Québec.ca, the Province of British Columbia and Ontario.ca, current in October 2026. Check the official pages for your own vehicle and route.

When do I need winter tires in Quebec in 2026?

The SAAQ is direct: "From December 1 to March 15 inclusive, all motorized road vehicles registered in Québec (other than heavy vehicles, tool vehicles and farm machinery) must be equipped with winter tires." That covers four tires, not two, and it includes rental cars, mopeds, motorized scooters and motorcycles.

Rule	Date
Studded tires allowed on passenger vehicles	from 15 October 2026
Winter tires mandatory	1 December 2026 to 15 March 2027
Studded tires no longer allowed	after 1 May 2027

The SAAQ also recommends going early: "Even though winter tires are not mandatory before December 1, winter can arrive early." Québec.ca suggests the same caution at the other end, recommending you "wait until a few weeks after the end of this period" before switching back to all-season or summer tires.

If your vehicle is not equipped between 1 December and 15 March, "The fine varies from $200 to $300, plus costs."

Who is exempt from Quebec's winter tire rule?

According to the SAAQ, the requirement does not apply:

• for the first 7 days after buying a vehicle from a dealer
• for the last 7 days before the end of a lease of 12 months or more
• to vehicles with dealer (X) plates, or with a temporary (transit) registration for up to 7 days
• to motor homes and to the spare tire
• to vehicles with a winter tire exemption certificate, requested through SAAQclic or at a service outlet

Québec.ca adds that the rule does not apply to trailers or to vehicles registered outside Québec. A visitor's car is not covered by the rule, though the roads are the same.

What counts as a winter tire in Quebec?

Since 15 December 2014, only tires carrying the official winter pictogram (the three-peaked mountain with a snowflake), or studded tires, count as winter tires under Quebec's Highway Safety Code. An "M+S" all-season tire does not.

For tires you are putting back on from last year, the SAAQ says the tread "should be at least 4.8 mm (6/32 in) across the entire width of the tire when they are installed." If last winter wore them close to that, you may need new ones, which takes longer to sort out than a simple swap.

When do I need winter tires in B.C.?

British Columbia works differently. There is no province-wide date for every road; instead, signed highways require winter tires or chains. The Province says: "Drivers must obey winter tire and chain signs throughout the province from October 1 to April 30. For select highways not located through mountain passes and/or high snowfall areas, tire and chain requirements end March 31."

The Province notes: "Most B.C. highways have high mountain passes where you are likely to encounter winter weather starting in October." The Province's list of winter tire and chain-up routes, and the roadside signs, tell you which sections apply; if your trip crosses a mountain pass, plan on needing them.

A legal winter tire in B.C. is looser than Quebec's definition. It must have "at least 3.5 mm of tread depth" and carry either the M+S marking or the mountain/snowflake symbol, and you need at least two matching winter tires on the primary drive axle. The Province recommends four mountain/snowflake tires, and chains for extreme conditions. Studded tires are allowed from 1 October to 30 April. The fine for a passenger vehicle without winter tires where they are required is $121.

What about Ontario and the rest of Canada?

There is no winter tire law in Ontario, but Ontario.ca makes the case for them: they shorten braking distances "by as much as 25%", and all-season tires "can start to lose grip at 7°C". It also says: "You could also get a discount on your auto insurance – ask your insurance provider." If you are entitled to a discount, check that it has actually been applied when your policy renews.

The 7°C figure comes up in the SAAQ guidance too: below that temperature, the rubber of summer and all-season tires "hardens and loses its grip." In much of Canada, that is a late-October or November night, well before any legal deadline.

When should I book the tire change?

Treat the deadline as the last possible day, not the target. A simple plan:

1. Now (early October): check last year's tires for wear and the right symbol. In Quebec, measure the tread against 4.8 mm; in B.C., against 3.5 mm.
2. Mid-October: book the swap. In Quebec, studded tires can go on from 15 October.
3. First nights near 7°C: that is the practical signal to change, whatever the date.
4. By late November (Quebec): tires on, with a few days spare before Tuesday 1 December.
5. Spring: in Quebec, not before 15 March, and ideally a few weeks later; in B.C., check whether your routes run to 31 March or 30 April.

If you drive a rental or have just bought a car, check the dates of any exemption before relying on it.

How ReminderIt can help

Tire swaps are a classic job that slips because nothing forces it until the first snowfall. ReminderIt places a real phone call at the exact time you choose and reads your reminder in a natural voice, for example "Book the winter tire change today. Quebec deadline is 1 December." If the call is missed, you get a WhatsApp message.

You can set reminders by sending a WhatsApp message (text, voice note or a photo of your garage's appointment card), such as "Call me on 15 October at 9am to book my winter tires", or on the website. There is no app to install. You can also set the call for a family member, for example a parent who still drives or a student with their first car; they confirm first.

There is a 7-day free trial with 7 free reminder calls (3 if your number is in a country where calls cost more). After that it is one plan, $7 a month, with annual and 2-year options.

The short answer

Quebec: four winter tires with the mountain/snowflake pictogram (or studded tires) from 1 December 2026 to 15 March 2027, with a $200 to $300 fine if you are caught without them. B.C.: obey winter tire and chain signs from 1 October 2026 to 30 April 2027 (31 March on some lower routes), with at least 3.5 mm of tread and an M+S or mountain/snowflake marking. Everywhere else, the official advice is to change once temperatures fall to around 7°C, and to ask your insurer about a discount.
