When must you use winter tires in Ontario?

Using winter tires in Ontario from December 1 to April 15 is a crucial requirement due to the typically harsh winter conditions experienced during this period. Winter tires are specifically designed to provide better traction, handling, and braking on ice and snow, which are common during these months.

The choice emphasizes that winter tires should be used regardless of whether conditions are slick, as winter weather can be unpredictable, and even a small amount of snow or ice can make roads hazardous. This period also coincides with other regulations related to vehicle safety and preparedness for winter driving conditions in the province.

In contrast, other options suggest specific circumstances for tire use that do not account for the broader, safety-oriented reason behind the regulation. For instance, only using winter tires during a snowstorm does not prepare motorists adequately for sudden changes in weather. Driving year-round with winter tires might lead to unnecessary wear in warmer months since they are designed for colder temperatures. Furthermore, the suggestion of only using them off-road does not relate to the primary purpose of enhancing road safety in typical on-road driving scenarios during the winter months.
