Motor Vehicle Act Section 208 (1) For the purpose of this section, "winter tire" is a tire that is: (a) advertised or represented by its manufacturer or a person in the business of selling tires to be a tire intended principally for winter use, and that provides, or is designed to provide, adequate traction in snow or mud; and (b) in the condition respecting tread wear and other particulars the regulations prescribe. (2) The minister responsible for the administration of the Transportation Act may, by public notice or by placing signs, prohibit vehicles from being driven or operated on a highway that are not equipped with chains, winter tires or sanding devices, or a combination of these the minister considers adequate and necessary in view of prevailing road conditions.

Are all-season tires considered to be winter tires?
NO. All-season tires are not by law approved winter tires because they are not intended principally for winter use. Winter tires will have a symbol of a mountain peak with a snowflake on the sidewalls.
Tires marked with the letters
mud and snow, provide safe all-weather condition, but may not always be suitable for severe snow conditions.
M+S rating is not a reliable indicator of a good winter tire. Consumers should research their tire options and make an informed decision that may save lives on an icy road.
The law also says a winter tire must have no less than 3.5 mm of rubber tread on it.
