Can Ontario LAT Extend the Two-Year Accident Benefits Deadline?

What Is the Two-Year Deadline for Ontario Accident Benefits Claims?

If your insurer denies or stops paying an accident benefit, you have two years to bring your dispute to the Licence Appeal Tribunal (LAT). This deadline begins when the insurer refuses or fails to pay the benefit in question. Missing it can mean losing your right to pursue the claim entirely, regardless of how strong your case might otherwise be.

This limitation period applies to most accident benefits disputes in Ontario, including claims for income replacement benefits, medical and rehabilitation benefits, and attendant care. It is set out in the Insurance Act and the Statutory Accident Benefits Schedule, and the LAT takes it seriously.

What Happens If You Apply to the LAT After the Two-Year Limit?

When a claimant files a LAT application outside the two-year window, the Tribunal does not simply dismiss it outright. Instead, the Tribunal will typically schedule a preliminary hearing to decide whether it has the authority to extend the deadline before anything else is considered.

In Arthur v Security National Insurance Company, 2026 CanLII 68562 (ON LAT), the Tribunal treated the extension question as a preliminary matter — a threshold issue that had to be resolved first. This procedural step is important because it gives claimants a structured opportunity to argue why their late filing should still be accepted.

Can the LAT Actually Extend the Two-Year Limitation Period?

The short answer is: it depends on the specific facts and the Tribunal’s jurisdiction under the applicable legislation. The LAT does have some procedural discretion, but it operates within statutory boundaries. Not every late application will qualify for an extension.

Factors that may be relevant include how the insurer communicated its denial, whether that communication was sent by regular mail and whether the claimant actually received it, and whether the claimant had a reasonable understanding of when the limitation period began to run. These are not automatic excuses, but they are legally relevant considerations that can affect when the clock actually started.

Does It Matter How the Insurer Sent Its Denial Letter?

Yes — the method of delivery can matter significantly. When an insurer sends a denial by regular mail, questions can arise about whether the letter was received, when it was received, and whether it clearly communicated the information needed to trigger the limitation period.

Ontario courts and tribunals have recognized that a limitation period generally begins when a claimant knows, or ought reasonably to know, that a claim exists and that an insurer has denied it. If the denial letter was lost in the mail or was unclear about the claimant’s appeal rights, that could affect when the two-year clock actually started — though this is a fact-specific analysis.

What Should You Do If You Think You Missed the LAT Deadline?

Do not assume your claim is over. The first step is to find out exactly when the insurer’s denial was issued, how it was communicated, and what it said. If there is any question about whether you actually received proper notice, that information could support an argument that the limitation period had not yet started — or that an extension is warranted.

Our Ontario litigation lawyers regularly assist clients who are navigating accident benefits disputes, including situations where timing and procedural deadlines are at issue. Getting legal advice quickly is essential, because delay after discovering a potential problem can itself become a barrier.

Practical Takeaways for Accident Benefits Claimants

• Track every denial letter carefully. Note the date you received it, how it was delivered, and whether it explained your right to dispute the decision at the LAT.
• The two-year clock usually starts from the insurer’s denial — not from the accident date. Knowing when your specific limitation period began is critical.
• A late application is not automatically dead. If you believe you missed the deadline, speak to a lawyer before giving up — the circumstances of how you were notified may matter.
• Preliminary hearings are real proceedings. If the LAT schedules a hearing on the limitation issue, you need to be prepared with evidence and legal argument, not just an explanation.
• Act quickly once you realize there may be a problem. Further delay after discovering a potential limitation issue can weaken your position at a preliminary hearing.

Why Does This Decision Matter for Ontario Injury Claimants?

This case is a practical reminder that procedural deadlines in accident benefits disputes are not just administrative formalities — they can determine whether your claim is heard at all. The LAT’s decision to treat the extension request as a standalone preliminary matter reflects how seriously the Tribunal takes its jurisdictional limits.
