Winter is a season that requires the most preparation. Your car is one of the most important, it gives you the foundation for safe winter driving and keeping it properly equipped will help you arrive safe when the winter weather hits.
1. Winter Tire Check In
Changing your tires is one of the most important steps in the winter car touch up. When temparatures drop below 7°C, it's time to put on your winter tires. All seasons and summer tires begin to lose traction, making sliding and skidding much more likely.
When looking to purchase winter tires, choose tires marked with a three-peaked mountain and snowflake. This symbol means they have passed a government-regulated traction test.
Once you find tires or go to install your current pair follow these steps:
-
Inspect all tires for any cracks, bald spots and check the tread. To quickly check your tread depth, insert a toonie between two treads. If the treads cover more than a quarter of the toonie, you're set for another year. Read More Tread Tips Here
- Use four matching tires. Cars with only two winter tires significantly underperform in handling compared to those that have them on all wheels.
-
Tire pressure goes down when cold temperatures hit. Check the air pressure often, it helps extend tread life, improves safety and reduces fuel consumption.
2. Test Your Car Battery
Cold weather slows your battery’s chemical reactions, reducing its ability to start your car. Have it tested before winter sets in to ensure it’s holding a charge. Most car batteries last 3–5 years — if yours is older, it might be time for a replacement.

3. Inspect Wipers and Washer Fluid
Visibility is everything in winter driving. Replace wiper blades at least once a year, and use cold-weather washer fluid rated for subzero temperatures.
4. Top Up Antifreeze and Other Fluids
Antifreeze (or coolant) prevents your engine from freezing and overheating. Check levels and inspect hoses for leaks or cracks.
5. Check Your Brakes and Lights
Winter roads are slippery — you’ll rely on your brakes more than ever. Have them inspected by a professional, and make sure all exterior lights are clean and functional.
6. Replace Your Cabin Air Filter
A fresh filter helps your heater and defroster run efficiently, keeping your windshield clear and your cabin comfortable.
7. Keep Your Fuel Tank at Least Half Full
This prevents moisture from freezing in your fuel lines and ensures you have enough gas to run the engine if you’re ever stuck in traffic or waiting for assistance.
8. Pack a Winter Emergency Kit
Include essentials like a flashlight, blanket, non-perishable snacks, booster cables, and a small shovel. These items can make a big difference if you’re stranded in cold weather.

9. Test Your Heater and Defroster
Make sure your heating system works well before you need it. Check for strange smells or uneven airflow.
10. Schedule a Pre-Winter Maintenance Check
A professional inspection can catch small issues before they become expensive repairs.
Bonus Tip: Take It for a Spin
After your prep, take your car for a short drive. Listen for any new noises, check your brakes, and ensure smooth steering and acceleration.
