Physiotherapy after a car accident in Ontario is generally addressed through accident benefits, subject to the applicable policy, treatment plan and insurer response. Medical and rehabilitation benefits remain mandatory, and auto insurance now pays first for those expenses except medication. This guide explains approval, clinics and practical next steps.
Key takeaways: Choose a suitable clinic, ask for an OCF-18 treatment and assessment plan, keep insurer responses, and read any payment direction before signing.
Treatment is funded through your accident benefits
In Ontario, accident benefits are paid by your own auto insurer (or another applicable insurer) whoever caused the accident. Medical and rehabilitation benefits cover treatment that OHIP generally does not, such as physiotherapy, massage therapy, chiropractic care, occupational therapy and psychological treatment. Since July 1, 2026, medical, rehabilitation and attendant care benefits remain mandatory under every standard Ontario auto policy, while most other benefits are optional.
Who pays first: the July 1, 2026 change
Before the reform, injured people were often told to claim first through a workplace or private extended health plan, and to go to the auto insurer only once that coverage ran out. That order has changed. According to the Insurance Bureau of Canada and FSRA materials on the new OPCF 47R endorsement (“Optional accident benefits coverage & priority of payment”), since July 1, 2026 auto insurance pays first for medical and rehabilitation expenses, except medication, ahead of workplace or private health plans.
Which rules apply to you can depend on when the accident happened and which policy is in place. If your accident happened before July 1, 2026, or your policy has not yet been renewed under the new endorsement, the earlier rules may still apply. Confirm the position with your insurer, or get advice, before you decide which plan to bill.
Choosing a clinic
You can generally choose your own treatment provider. Some practical points:
• Convenience matters. Treatment usually works best when you attend regularly, and a clinic close to home or work makes that easier.
• Experience with auto claims helps. Choose a clinic that regularly bills auto insurers.
• Check HCAI registration. Ontario auto insurers receive treatment plans and invoices electronically through Health Claims for Auto Insurance (HCAI). A clinic that is set up on HCAI can submit forms directly.
Some clinics may ask you to pay out of pocket at first. If you have reported the accident and applied for accident benefits, ask the clinic to bill your auto insurer instead.
How treatment is approved: the OCF-18
Treatment is usually requested with an OCF-18 Treatment and Assessment Plan. Your provider prepares it, describing your injuries, the proposed treatment and its cost, and submits it to the insurer. The insurer then reviews it and may:
• approve the plan in full;
• approve part of it;
• deny it; or
• ask for an insurer examination or a paper review by a health professional it selects, to assess whether the treatment is reasonable and necessary.
The insurer must respond within the time limits set out in the SABS, and its response should give reasons for any denial. Keep copies of every OCF-18 and every response. If treatment is denied, ask your provider whether a revised plan is appropriate, and read our guide on what to do when accident benefits are denied.
The Minor Injury Guideline
Some injuries, such as many sprains, strains and whiplash-type injuries, may be treated under the Minor Injury Guideline. This framework sets out a defined treatment path and a lower funding limit than other injuries. Whether an injury falls inside or outside the guideline can make a large difference to the treatment available. If there is evidence of a pre-existing condition, or of an injury that is not minor (such as a psychological injury or a fracture), that evidence should be documented by your health providers. (The current guideline and its limits should be confirmed before you rely on them.)
Read clinic payment documents carefully
Some clinics ask patients to sign an “irrevocable direction”, a “promise to pay” or a similar document. These may say that you are responsible for unpaid invoices, that interest builds up on outstanding amounts, or that the clinic will be paid directly from any settlement in a later lawsuit.
These documents are not necessarily improper, but they can have serious financial consequences. Before signing, ask for a copy, read it fully, and ask what happens if the insurer denies a plan. If you have a lawyer, ask them to review it.
Practical steps
1. Report the accident to your insurer and apply for accident benefits.
2. Choose a convenient clinic that bills auto insurers through HCAI.
3. Ask the clinic to submit an OCF-18 before or at the start of treatment.
4. Keep copies of each plan, approval or denial, and every invoice.
5. Attend appointments consistently and tell your providers about every symptom.
6. Read any payment direction or promise to pay before signing it.
Tell your providers everything
Treatment plans are only as good as the information behind them. Tell your physiotherapist, family doctor and other providers about every symptom, including headaches, sleep problems, anxiety, and pain that comes and goes. Tell them about any condition you had before the accident and how the accident changed it. Accurate records help providers recommend the right treatment, and help the insurer see why it is needed. If your symptoms change or new problems appear, report them promptly so that your plan can be updated.
If you do not have your own auto policy
Pedestrians, cyclists, passengers and others without their own auto policy may still be able to claim medical and rehabilitation benefits. They may claim through the policy of a household member, the insurer of a vehicle involved in the accident, or, in some cases, another source. The rules on which insurer pays can be complex. Since July 1, 2026, optional benefits may not extend to people who are not named or listed on a policy, but medical and rehabilitation benefits remain part of the mandatory coverage. If you are unsure which insurer to apply to, ask before you start treatment, so that the correct insurer receives your OCF-18 from the start.
