The usual advice in Ontario is to put winter tires on when temperatures stay around 7°C or below. In Mississauga and across the Greater Toronto Area, that stretch often starts in late October or November. Booking early helps you avoid the rush once the first stretch of cold weather arrives.
CityNews Toronto reported on November 6, 2026 that the top question shops were hearing was about timing, and the advice was to switch around 7°C or below. That temperature is a practical guide, not a calendar date, because a mild week can be followed quickly by colder mornings.
Why 7°C is the usual switch point
Winter tire rubber stays flexible in the cold, which helps the tire keep grip on cold pavement, slush, and snow. All season tires are built for a wider range of temperatures, and their rubber can harden as the air gets colder. You do not need to wait for the first snowfall. If daytime and overnight temperatures are staying around 7°C or lower, it is time to make the change.
Insurance dates vary, so check your own policy
Ontario is the only province that requires insurers to offer a winter tire discount, usually 2% to 5%, according to The Globe and Mail. The date you need the tires installed depends on your insurer.
CAA Insurance wants winter tires on by November 20 for its 5% discount. Other insurers use dates from November 1 to December 1, so the safest step is to read your own policy or ask your broker. Year-round all weather tires usually do not qualify for the discount. Most insurers look for winter tires that carry the mountain snowflake symbol.
Use a set of four with the mountain snowflake symbol
Look for the mountain snowflake symbol on the sidewall. That mark shows the tire meets a recognized winter traction standard. Winter tires should go on as a set of four so all four wheels have the same grip. Mixing winter tires at one end of the vehicle with a different type at the other can make the car harder to control.
If you already have a set in storage, have them checked for tread depth, cracks, and even wear before they go back on. If you need a new set, plan for four matching winter tires, not a pair.
