What Affects Your Car Insurance Premium?
Ontario has some of the highest auto insurance premiums in Canada. Understanding the factors that drive your rate helps you make informed decisions — about the vehicle you buy, where you live, and how you use it.
Your Vehicle
The make, model, and year of your vehicle is one of the most significant rating factors. Insurers use claims data to assess how often a particular vehicle is stolen, how expensive it is to repair, and how well it protects occupants in a collision. A vehicle with a high theft rate — such as certain Honda CR-V and Toyota Highlander model years, which have appeared on the IBC's most-stolen list — will carry a higher comprehensive premium. A vehicle with expensive parts or specialized repair requirements will carry a higher collision premium. Before buying, ask your broker for an insurance quote on the specific year and trim you're considering.
Your Driving Record
At-fault accidents and traffic convictions remain on your Ontario driving record for three years (minor convictions) to six years (major convictions and at-fault accidents). Each at-fault accident or conviction can increase your premium significantly — and some insurers will decline to cover drivers with multiple incidents. A clean record, by contrast, qualifies you for claims-free discounts that compound over time. Telematics programs offered by some insurers let you demonstrate safe driving habits in exchange for a discount, regardless of your record.
Where You Live
Your postal code affects your premium because insurers price based on the claims experience in your area. Urban areas — particularly parts of the GTA — have historically higher rates due to greater traffic density, higher theft rates, and more frequent collisions. Moving from one GTA city to another can change your premium meaningfully, even if nothing else about your situation changes. This is one reason why comparing rates when you move is worthwhile.
How You Use Your Vehicle
Insurers distinguish between pleasure use (occasional personal driving), commuting (regular travel to a fixed workplace), and business use (using your vehicle for work purposes beyond commuting). Annual kilometres also matter: the more you drive, the greater your statistical exposure to a claim. If you work from home or use transit for your commute, updating your policy to reflect lower annual mileage may reduce your premium.
Your Coverage Choices
The coverage types and limits you select directly affect your premium. Ontario's mandatory minimum third-party liability limit is $200,000, but most advisors recommend at least $1 million or $2 million. Adding optional coverages — collision, comprehensive, loss of use, and others — increases your premium. Raising your deductible lowers it. Your choices here represent the most direct lever you have over your premium, though they also affect your protection.
Other Factors
Additional factors that may affect your premium include: the number of drivers on the policy and their records; whether the vehicle is financed (lenders typically require collision and comprehensive); your insurance history and any gaps in coverage; and discounts for bundling home and auto insurance with the same insurer. Ontario insurers are not permitted to use credit scores as a rating factor.
