Inspect Your Tires

One of the most critical steps in preparing your car for Ontario's harsh winters is ensuring your tires are up to the task. Winter-specific tires provide better traction on snow and ice, reducing the likelihood of skidding. Make sure your tires have a tread depth of at least 6/32 inches for optimal performance. If they don't, consider replacing them before the snow starts falling.

Check Tire Pressure

Cold temperatures can cause tire pressure to drop, affecting your vehicle's handling and fuel efficiency. Regularly check and maintain the recommended tire pressure throughout the winter months. This simple step can make a significant difference in your car's performance and safety.

Prepare Your Battery

Winter weather can be tough on car batteries. To avoid being stranded, check your battery's health and replace it if necessary. Clean the battery terminals and ensure all connections are secure. Consider keeping jumper cables in your car just in case your battery does fail.

Fluids and Antifreeze

It's essential to check all your car's fluid levels, including oil, brake fluid, and windshield washer fluid. Use a washer fluid rated for -40 degrees Celsius to prevent freezing. Additionally, ensure your antifreeze is at the correct mixture to prevent your engine from freezing and overheating.

Inspect Your Wipers

Visibility is crucial during winter, so make sure your windshield wipers are in excellent condition. Consider investing in winter wiper blades designed to handle snow and ice. Ensure your defroster and heating systems are functioning well to keep your windshield clear.

Emergency Kit

Prepare an emergency kit to keep in your car during the winter months. This should include items such as a blanket, flashlight, extra batteries, non-perishable snacks, and a first-aid kit. Having these essentials can provide peace of mind in case of an unexpected breakdown or delay.

Keep Your Car Clean

While it might seem counterintuitive, regularly washing your car in winter can prevent rust and corrosion from road salt. Pay special attention to the undercarriage, where salt and grime tend to accumulate. A clean car not only looks good but also performs better in the long run.

Check Your Lights

With reduced daylight hours, ensure all your car's lights are functioning correctly. This includes headlights, taillights, brake lights, and turn signals. Replace any burnt-out bulbs and consider using brighter bulbs for increased visibility.
