Winter TyresCanada Winter Tyres 2026: Quebec 1 Dec, BC Highways 1 Oct
Only Quebec (1 Dec to 15 Mar, snowflake pictogram, $200-300 fine) and BC's signed highways (1 Oct to 30 Apr, $121 fine) require winter tyres. Elsewhere it's your call.
Canada has no national winter tyre law. Quebec requires them from 1 December to 15 March; British Columbia requires them on signed highways from 1 October to 30 April. The other provinces set no requirement.
Quebec: a fixed date and a pictogram
From 1 December to 15 March inclusive, every motor vehicle registered in Quebec, rental cars included, must be on winter tyres. Heavy vehicles, tool vehicles and farm machinery are outside the rule. A tyre counts only if it carries the three-peak mountain snowflake pictogram or is studded; an M+S stamp alone does not qualify. The fine is $200 to $300.
Quebec’s legal tread minimum is 1.6 mm, but the province recommends at least 4.8 mm for winter. Studs are allowed on passenger vehicles, taxis and light commercial vehicles up to 3,000 kg from 15 October to 1 May.
If you rent in Quebec in winter, the car will already be compliant. If you drive in from Ontario or the US, the Quebec obligation is written for Quebec-registered vehicles, but the roads do not care where your plates are from.
British Columbia: signed highways, not the whole province
BC’s rule applies on highways marked with the winter tyre and chain signs. On most of them the requirement runs from 1 October to 30 April; a handful of routes outside mountain passes and high-snowfall areas end on 31 March. A tyre qualifies with the M+S marking or the mountain snowflake symbol and at least 3.5 mm of tread, and you need at least two matching winter tyres on the primary drive axle, four-wheel drive or not. Summer tyres with chains are not an alternative for passenger cars.
Police, the ministry and commercial vehicle enforcement officers can turn a non-compliant car back. The fine for a passenger vehicle without winter tyres is $121 under section 125 of the Motor Vehicle Act.
Everywhere else
Ontario, the Prairie provinces and the Atlantic provinces have no winter tyre mandate. That is a legal statement, not a weather one: winters there are as hard as Quebec’s, and most drivers fit winter tyres regardless.
