Car Insurance After an Accident in Ontario
An accident does not translate into one automatic insurance increase. Fault, claim payments, prior history, accident-forgiveness rules and the insurer's approved rating system all matter.
How is fault determined after an Ontario accident?
FSRA explains that insurers determine fault using Ontario's Fault Determination Rules. A driver can be charged by police and still receive a different insurance fault assessment; similarly, not receiving a charge does not automatically mean the driver is considered not at fault for insurance purposes.
If you disagree with the insurer's assessment, FSRA recommends asking the claims adjuster which Fault Determination Rule was applied and using the insurer's complaint process if the dispute is not resolved.
FSRA — After an Accident: Understanding the Claims Process →Some minor at-fault accidents cannot be used to increase premiums
FSRA says an insurer cannot use a minor at-fault accident occurring on or after June 1, 2016 to increase premiums when specific criteria are met: no insurer payment, no injuries, damage under C$2,000 per vehicle/property and the at-fault driver paid the damage. The protection is limited to one such minor accident every three years.
FSRA — Minor accident and accident-forgiveness guidance →Can an at-fault accident increase the premium?
Previous accidents are part of the driving record FSRA says insurers can use in pricing. An at-fault claim can therefore affect a future premium, but there is no single Ontario-wide percentage increase that applies to every accident or every insurer.
The result can depend on prior claims, fault percentage, policy endorsements, insurer rules and whether the claim qualifies for a statutory minor-accident protection.
FSRA — Driving record and insurance rates →What is accident forgiveness?
FSRA says most insurers have some accident-forgiveness provisions or offer an endorsement that can provide this protection. The conditions vary by insurer and policy, so the endorsement wording matters more than the marketing name.
Accident forgiveness does not make the accident disappear from every record and should not be assumed to transfer unchanged to another insurer. The practical question is how the current insurer treats the claim at renewal under the policy you bought.
FSRA — Claims or accident forgiveness →What should you compare at renewal?
Compare the old and new annual premium using the same coverage, deductibles and listed drivers. If coverage changed at the same time as the claim, a simple before-and-after premium comparison will mix multiple effects.
Canada Rate Lab's renewal calculator measures the change without pretending to know how much of it came from the accident, insurer-wide rate changes or other profile updates.

No. FSRA averages are market benchmarks. Your vehicle, postal area, driving record, years licensed, annual kilometres, coverage, deductible and insurer can produce a materially different premium.
