Key Takeaway

Before winter weather hits, review your auto insurance to ensure adequate collision and comprehensive coverage, verify your deductible fits your budget, claim available winter tire discounts (typically 5 to 10 percent), update your annual mileage estimate, and confirm you have roadside assistance for breakdowns in harsh conditions. Autumn is the ideal time to make adjustments before insurance needs spike in winter months.

Why Review Your Car Insurance in Autumn

Canadian winters bring snow, ice, freezing rain, and reduced visibility, all of which increase collision risks and comprehensive claims for damage from falling ice, vandalism during extended parking, and weather-related incidents. According to the Insurance Bureau of Canada, collision claims rise significantly during winter months across most provinces (IBC, 2026). Reviewing your policy in September or October gives you time to adjust coverage, add discounts, and ensure you are protected before the first snowfall.

Insurance products and coverage rules vary by province and territory. In provinces with public auto insurance (British Columbia through ICBC, Saskatchewan through SGI, Manitoba through MPI, and Quebec’s public bodily injury coverage through the SAAQ), review your optional coverage add-ons and endorsements. In private-market provinces such as Ontario and Alberta, shop around or contact your broker to verify you have the right balance of coverage and cost.

Your Autumn Car Insurance Checklist

1. Review Your Liability Coverage Limits

Third party liability coverage pays for injury or property damage you cause to others. Most provinces require a minimum of C$200,000, but the Insurance Bureau of Canada and consumer advocates recommend at least C$1 million to C$2 million given rising repair costs and injury settlements. Winter driving increases accident risk. Verify your liability limit and consider increasing it if you carry the minimum.

2. Check Collision and Comprehensive Coverage

Collision coverage pays to repair or replace your vehicle after a crash, regardless of fault. Comprehensive coverage pays for non-collision damage such as theft, vandalism, fire, falling objects, or hitting an animal. Winter brings all of these risks: sliding into another car on ice (collision), a heavy snow load cracking your windshield (comprehensive), or hitting a moose on a rural highway (comprehensive). If you have a loan or lease, your lender likely requires both. If you own your vehicle outright, verify the coverage still makes financial sense given your car’s current value.

3. Verify Your Deductible Amount

Your deductible is the amount you pay out of pocket before insurance coverage begins. Common amounts range from C$500 to C$1,000, though you can choose higher or lower. A higher deductible lowers your premium but increases your upfront cost after a claim. Before winter, confirm you can afford your deductible if you slide into a snowbank or your windshield cracks from flying ice. If the deductible feels too high, contact your insurer or broker to lower it. Keep in mind that lowering your deductible will increase your premium.

4. Claim Your Winter Tire Discount

Most private insurers in Ontario, Quebec, Alberta, and other provinces offer a discount (typically 5 to 10 percent on certain coverages) if you install four winter tires. Some provinces, such as Quebec, legally require winter tires from December 1 to March 15. Even where not mandatory, winter tires improve traction and braking on snow and ice. If you have winter tires, notify your insurer and provide proof of installation (a receipt showing the tire type and installation date). The discount usually applies from the date you install the tires until you remove them in spring, so claim it as soon as you switch over.

5. Update Your Annual Mileage Estimate

If you drive less in winter due to remote work, shortened trips, or avoiding poor weather, your annual mileage may have dropped. Insurers base premiums partly on how much you drive. Contact your insurer to update your estimate. A lower mileage classification can reduce your premium. Conversely, if you are driving more (a new commute, winter travel), report the increase to avoid a coverage gap.

6. Add or Confirm Roadside Assistance Coverage

Roadside assistance pays for towing, battery boosts, lockout service, and fuel delivery. Winter breakdowns are common: dead batteries in extreme cold, getting stuck in snow, or mechanical failure in remote areas. Many policies include basic roadside assistance or offer it as an optional add-on for C$20 to C$50 per year. Verify you have it, check the coverage limits (towing distance, number of service calls per year), and confirm the contact number is saved in your phone.

7. Review Your Declarations Page and Update Personal Information

Your declarations page (often called the dec sheet) lists your vehicle details, coverage types, limits, deductibles, drivers on the policy, and your address. Verify everything is accurate. If you moved, changed your vehicle usage (commuting to pleasure use), added or removed a driver, or bought a different vehicle, update your policy. Incorrect information can delay a claim or result in a coverage denial.

8. Check for Additional Endorsements You May Need

Endorsements (also called riders) are optional add-ons. Common ones for winter include:

  • Accident forgiveness: protects your premium from increasing after your first at-fault claim.
  • Rental car coverage: pays for a rental vehicle while yours is being repaired after a covered loss.
  • Increased coverage for custom equipment: if you have winter-specific modifications (a remote starter, upgraded headlights), verify they are covered.

Review your endorsements and add any that fit your winter driving needs.

Common Mistakes When Reviewing Car Insurance

  • Assuming coverage is automatic: winter tire discounts and mileage reductions require you to notify your insurer. They do not apply automatically.
  • Skipping the deductible check: a low premium with a C$2,000 deductible can leave you unable to afford a repair after a winter claim.
  • Not shopping around: loyalty does not always pay in insurance. Rates vary significantly between insurers. Get quotes from at least three providers or work with a licensed broker.
  • Ignoring provincial differences: auto insurance rules differ sharply by province. Confirm requirements with your provincial regulator (FSRA in Ontario, the AMF in Quebec, ICBC in British Columbia, and others).

Frequently Asked Questions

When is the best time to review my car insurance for winter?

September or early October, before the first snowfall. This gives you time to adjust coverage, claim discounts, and shop around without rushing.

Do I need to notify my insurer every year when I install winter tires?

Most insurers require annual confirmation. Some apply the discount automatically if you claimed it the previous year, but call to verify.

Can I lower my premium by parking my car for the winter?

If you store your vehicle and do not drive it, you can suspend collision coverage and keep only comprehensive (for fire, theft, vandalism). Contact your insurer to adjust your policy. You cannot cancel liability coverage entirely in most provinces.

What if I have an accident during my review period before updating my coverage?

Your current policy terms apply. If you were planning to increase your collision coverage but had not yet done so, your claim is subject to the old, lower limit. Make changes promptly.

Conclusion

Autumn is the right time to review your auto insurance and prepare for Canadian winter driving. Work through this checklist: verify your liability limits, confirm collision and comprehensive coverage, check your deductible, claim winter tire discounts, update your mileage, and add roadside assistance if you do not have it. Contact a licensed insurance broker or agent for a policy review tailored to your province and driving situation, and confirm requirements with your provincial regulator. As foundational texts such as Principles of Finance explain, insurance is about transferring risk you cannot afford to bear on your own. Winter driving in Canada presents real risks, and the right coverage, reviewed in advance, protects you when conditions turn harsh.
