Ontario legal information · Sources appear with each important rule

01 · The insurer’s reason

Turn the denial into a list of disputed questions

Look for the benefit claimed, treatment dates, SABS provision, clinical reason, policy limit or classification relied upon. Note whether the insurer requests more information or an examination.

The regulation sets rules for treatment and assessment plans and insurer responses.1 The current OCF-18 is published by FSRA.2

Read the full decision. A short denial label may hide several separate factual or legal questions.
02 · Clinical reasoning

Check whether the OCF-18 tells one consistent story

Read these parts together

  • The accident history and diagnosis
  • Current symptoms and functional limits
  • Prior and ongoing treatment
  • The service requested, duration and cost
  • The expected functional outcome

Correct factual errors with the provider. More pages are not automatically better; the plan needs to answer the actual entitlement question.

03 · The response

Use evidence that addresses the gap

If the insurer questions causation, the medical timeline may matter. If it disputes necessity, the provider may need to explain treatment response, alternatives and functional goals. If classification is the issue, the applicable SABS test and supporting record need attention.

Keep a copy of every plan, clinical report, insurer examination and explanation of benefits. FSRA’s forms library identifies the current accident-benefit forms.3

04 · LAT process

An internal reconsideration is not the only possible route

Disputes about entitlement to statutory accident benefits are generally brought to the Licence Appeal Tribunal’s Automobile Accident Benefits Service.4 The LAT process uses its own application, case conference, document exchange and hearing procedures.

Do not assume ongoing discussion with the adjuster pauses every procedural or legal deadline.

When legal help may matter

How a personal injury lawyer may help with accident benefits.

A useful review should reduce the file to a defined benefit, disputed period, governing test and evidence problem—then explain the available response in plain language.

  • Identify the benefit, policy, insurer and legal test that apply.
  • Answer the denial with medical, functional and financial evidence.
  • Protect application, examination, LAT and reconsideration deadlines.
