Ontario's accident benefits system is governed by the Statutory Accident Benefits Schedule (SABS). It includes time-sensitive notice, application, and dispute steps. Missing a deadline can seriously affect your ability to claim or dispute benefits, so urgent timing questions should be reviewed with a qualified legal professional promptly.
Here are the five deadlines Ontario accident victims most commonly miss, and what the consequences are.
1. The 7-Day Notice Requirement
When: Within 7 days of the accident. What: Notify your own insurer that an accident occurred.
After an accident, you are required to notify your automobile insurer as soon as practicable, and in any event within 7 days. This doesn't mean filing a claim — it means providing notice that the accident occurred. Many people wait to see how injuries develop before contacting anyone. That delay can cost you.
Failing to provide timely notice doesn't automatically bar your claim, but it can be used by your insurer to reduce or deny benefits if they can show they were prejudiced by the late notice.
2. The 30-Day Application Deadline
When: Within 30 days of receiving the OCF forms. What: Return completed accident benefit application forms.
Once you notify your insurer, they are required to send you application forms (OCF forms) within 10 business days. You then have 30 days to return the completed forms. Missing this deadline gives the insurer grounds to deny your claim entirely — not just delay it.
People often hold off on completing the forms because they're dealing with recovery, don't understand the paperwork, or are waiting to see if the injuries resolve on their own. That's a costly mistake.
3. The 104-Week Transition Period for Income Replacement
When: 2 years after the accident. What: Stricter test for income replacement benefits applies.
Income Replacement Benefits (IRB) initially pay if you cannot perform the "essential tasks" of your pre-accident job. After 104 weeks (2 years), the test changes — you must be unable to perform any job for which you are "reasonably suited by education, training, or experience." This is a significantly higher bar, and many claimants lose their IRB at this point without understanding why.
If you're approaching the 104-week mark and still have injury-related work limitations, you should have your situation reviewed before the transition happens — not after.
4. The 2-Year Limitation Period for Tort Claims
When: 2 years from date of accident. What: File a tort (lawsuit) claim against the at-fault party.
In addition to accident benefits through your own insurer, you may have the right to sue the at-fault party for damages (pain and suffering, future care costs, lost income beyond what SABS covers). This right expires 2 years from the date of the accident under Ontario's Limitations Act.
Missing this deadline is permanent. There are narrow exceptions for minors and certain cases of incapacity, but for most adults, the 2-year window is absolute.
5. The Dispute Deadline for LAT-AABS Applications
If you and your insurer disagree about your entitlement to accident benefits or the amount payable, you may be able to apply to the Licence Appeal Tribunal — Automobile Accident Benefits Service (LAT-AABS), subject to applicable rules and deadlines. Consider getting qualified legal advice promptly if a refusal, suspension, or termination letter mentions a deadline. Official source: https://tribunalsontario.ca/lat-aabs/
