Changing from winter to summer tires is something every Canadian car owner is familiar with. Getting your tires changed in Ontario should cost you somewhere in the range from $80 to $110 which covers getting the tires removed from the rim, mounted, balanced and then reinstalled.
Tires need to be changed in the winter and the spring so your total cost should not be more than $160 to $220 for the whole year. Always change all four tires on your vehicle to winter or summer tires, never mix different types of tires on your vehicle in any season.
