Car insurance by Ontario city

Every insurer in Ontario must file its rates and its risk-classification system with the Financial Services Regulatory Authority of Ontario (FSRA) and get approval before charging them. Geography is one of the approved classification variables. Insurers divide the province into rating territories and assign each address — down to the Forward Sortation Area, the first three characters of your postal code — a relativity reflecting the claims experience recorded there. Those territories rest on pooled industry data: the General Insurance Statistical Agency (GISA), the statistical agent for Ontario and eight other jurisdictions, collects claims and premium data from every licensed auto insurer under its Automobile Statistical Plan. Because rating is done at FSA level rather than by municipality, one city can straddle several territories, and each insurer files its own relativities — which is why two companies can quote the same address differently.

Ontario draws hard lines around risk classification. Under section 16 of R.R.O. 1990, Regulation 664, insurers are prohibited from using a long list of factors, including your income, employment history, credit history, credit rating, whether you hold a credit card, and your residence history. Credit-based scoring, permitted in some jurisdictions, is not allowed for Ontario auto rating. Race, ethnicity and religion appear on no permitted list and never have; Ontario's Unfair or Deceptive Acts or Practices rule (O. Reg. 7/00) defines a prohibited factor to include anything Regulation 664 bans plus "any other factor that is an estimate of, a surrogate for or analogous to a prohibited factor." What insurers can use is your driving record, claims history, years licensed, the vehicle, how much you drive, and where the vehicle is garaged — territory is legal because regulators treat it as a measure of loss experience, not of the people who live in an area.

In its 2022 value-for-money audit of FSRA (released November 30, 2022), the Auditor General of Ontario obtained ten car-insurance quotes in which the only factor changed was where the person lived, and reported that rates "ranged from $1,200 per year (when the individual lived in London) to $3,350 per year (when the person lived in Brampton) driving the same automobile." The same audit found the territorial framework used by FSRA had not been updated since 2005, that Ontarians pay the highest private passenger auto premiums in Canada, and that the average premium rose almost 14% to $1,642 between 2017 and 2021 — despite Ontario having one of the lowest rates of car-crash injuries in the country. The Auditor General's 2024 follow-up rated progress on the core recommendations as "little or no progress." This is a controlled illustration of how much address alone can move a quote, not a table of city averages — and it remains the only official city-level pricing comparison Ontario has published.

IBC publishes an annual ranking of Ontario's costliest cities for auto-theft claims. In the list released May 13, 2026, Toronto, Brampton and Mississauga held the top three places, Ottawa moved up two spots to fourth, Hamilton rose four places to fifth, and Vaughan sat seventh after ranking fourth the year before. Province-wide, Ontario auto-theft claims totalled $485 million in 2025, down from $723 million in 2024 but still far above 2017 levels, and IBC estimates theft adds roughly $130 to the average Ontario premium. This ranks claims cost, not premiums: a city's theft position tells you about one component of comprehensive coverage, not what a driver there pays overall.

Treat any published "average premium by city" table as unsourced unless it names the regulator or statistical agency behind it. What holds regardless of address: each insurer files its own territory relativities with FSRA, so the same postal code is priced differently across companies, and comparison is the lever that acts directly on that. FSRA began allowing insurers to make territory rating changes in the GTA from January 3, 2024, approving ten such applications by the end of July 2024 — loosening how territories may be drawn, not removing geographic rating. FSRA's Automobile Insurance Rating and Underwriting Supervision Guidance, whose final chapter took effect March 1, 2026, reorganised how insurers file rates and set fairness expectations; it does not ban territorial rating either.

Effective July 1, 2026, FSRA changed the Statutory Accident Benefits Schedule so that everything except medical, rehabilitation and attendant care benefits became optional, and narrowed eligibility for the newly optional benefits to the named insured, their spouse, dependants and listed drivers. Auto insurers also became first payer for medical and rehabilitation costs ahead of workplace or private health plans. This changes what you buy and how benefits are structured. It does not touch how insurers draw territories or price geography — the postal-code differential sits in a different part of the rating system and is unaffected. Whether dropping an optional benefit is sensible depends on what your workplace or private plan already covers; it is a coverage decision to review at renewal with a licensed professional, not a discount to take automatically.
