CanadaHow long do I have to file an insurance claim after a car accident?
In most Canadian provinces, you generally have 2 years from the date you discover your injury or loss to file a car accident insurance claim, but some provinces require immediate or very prompt reporting — often within 7 to 30 days — to preserve coverage rights.
What the Law Says
The time limit to file an insurance claim after a car accident in Canada depends on two things: (1) statutory limitation periods for suing, and (2) contractual reporting deadlines in your auto insurance policy. While limitation periods govern when you can go to court, insurance policies almost always require much faster notice — often within days — to keep your claim valid.
In Ontario, the Insurance Act requires that written notice of an automobile accident be given to the insurer 'as soon as practicable', and no later than 7 days after the accident — unless the insurer waives the delay. Failure to meet this deadline may allow the insurer to deny coverage.
Other provinces have similar rules. For example, Alberta’s Traffic Safety Act and British Columbia’s Insurance (Vehicle) Act also impose strict notice obligations, typically requiring prompt reporting — often interpreted as within 24 to 72 hours for serious accidents.
Importantly, the two-year limitation period to start a lawsuit (under provincial Limitations Acts) does not replace the shorter reporting deadlines in your insurance contract. Courts treat those deadlines as conditions precedent — meaning missing them can void your claim entirely, even if you’re still within the 2-year window to sue.
Statutory TextNotice of loss or damage shall be given to the insurer as soon as practicable and, in any event, within seven days after the occurrence of the loss or damage.

What Courts Have Said
Courts across Canada emphasize that insurance claim deadlines are strictly enforced — and that the general limitation period for lawsuits does not excuse late notice to the insurer.
The Court held that the limitation period for a motor vehicle negligence claim begins not on the date of the accident, but when the injured person discovers — or ought reasonably to have discovered — the injury, its significance, and its connection to the defendant's conduct. However, this 'discoverability principle' applies only to court actions, not to contractual insurance notice requirements, which remain strict and immediate.
What to Do
Contact your insurer or broker by phone or online within 24 hours — even for minor incidents.
Submit written notice (email or form) within 7 days, as required under Ontario law and common in other provinces.
Keep proof of when and how you reported — save emails, call logs, and confirmation numbers.
If you missed the deadline, contact your insurer immediately and explain why — some may waive it if the delay was reasonable and did not prejudice their investigation.
If your claim is denied due to late reporting, consult a lawyer promptly — you may still have options under consumer protection or fairness principles.
