Independent Medical Exam (IME) in Ontario: What to Expect and How to Protect Your Claim

If you have an Ontario injury claim, sooner or later the insurance company will send you to an "Independent Medical Examination." Despite the reassuring name, it is rarely neutral, and how you handle it can meaningfully change the outcome of your case. Here is a plain-language explanation of what an IME actually is, what happens during one, and the specific steps that protect your claim.

What Is an IME?

An Independent Medical Examination is an assessment performed by a doctor chosen and paid for by the insurance company — in accident-benefit (SABS) claims — or by the defence in a tort lawsuit. Its purpose is to give the insurer a medical opinion about your injuries, and in practice that opinion frequently minimizes them. The examiner is not your treating doctor, has no role in your recovery, and will usually see you only once. Their report becomes evidence the insurer can use to dispute your claim.

You can be required to attend IMEs under both Ontario's accident-benefits system and the tort process, which run in parallel after most motor vehicle accidents. Because refusing a properly arranged examination without a valid reason can suspend your benefits, these appointments are not optional, and they should never be treated casually. For background on how the two systems interact, see our guide to tort claims vs accident benefits in Ontario.

Why Insurers Order IMEs

An IME is a tool, and the insurer orders it with a goal in mind. The most common objectives are:

• To dispute that your injury is as serious as you and your treating doctors say.
• To argue your symptoms come from a pre-existing condition rather than the accident.
• To claim you have recovered, so that ongoing benefits can be cut off.
• To challenge whether you meet the "serious and permanent impairment" threshold that unlocks full pain-and-suffering damages.
• To build a documented record supporting a lower settlement.

Understanding the goal helps you understand the experience. The examiner is gathering evidence, and everything you say and do becomes part of that record.

What Actually Happens During the Exam

A typical IME lasts anywhere from twenty minutes to a couple of hours, depending on the injury and the specialty of the examiner. In general, the examiner will:

• Review your medical records — often before you even arrive.
• Ask how the accident happened and how you have been since.
• Ask detailed questions about your daily activities, your work, and your health before the accident.
• Perform a physical or psychological assessment appropriate to your injury.

It is important to understand that the assessment effectively begins before you walk into the exam room. Examiners — and the surveillance investigators insurers sometimes coordinate around IME dates — pay attention to how you move in the parking lot and the waiting room, how you sit, how you rise from a chair, and whether your described limitations match your observed behaviour. None of this means you should perform or exaggerate; it means you should simply be honest and consistent, because inconsistency is what damages credibility.

How to Protect Your Claim — The Do's

• Be honest, specific and consistent about your symptoms and how they affect your life. Consistency between what you tell the examiner, what is in your records, and how you actually function is the single most important thing.
• Describe your worst days as well as your good days. Many people instinctively minimize their pain to be polite or stoic. An examiner will record that minimization as evidence of recovery.
• Explain concrete functional limitations — the specific work tasks, chores, hobbies and family activities you can no longer do, or can only do with difficulty or pain.
• Arrive on time and prepared. Bring a list of your current medications, treatments and treating providers.
• Tell your lawyer the moment you receive an IME notice so you can be properly prepared before the appointment, not after.

How to Protect Your Claim — The Don'ts

• Do not exaggerate. Overstating symptoms is the fastest way to destroy your credibility and hand the insurer exactly what it wants.
• Do not minimize or "tough it out." Downplaying your pain is recorded as recovery and used to cut your benefits.
• Do not guess. If you do not know the answer to a question, "I don't know" or "I don't remember" is a perfectly acceptable response.
• Do not discuss your legal strategy or your settlement expectations with the examiner.
• Do not assume the appointment is informal. It is evidence-gathering, start to finish.

What If the IME Report Is Unfair?

IME reports frequently understate injuries, and many clients are upset when they read one. The good news is that a single unfavourable report is not the end of your claim. An experienced lawyer has several tools to respond:

• Obtain a rebuttal report from a qualified, genuinely independent specialist who has examined you properly.
• Cross-examine the examiner's methodology — the time spent, the assumptions made, the records reviewed or ignored, and any history of working almost exclusively for insurers.
• Rely on your treating doctors, who have seen you over months and know far more about your condition than a one-time examiner.
• Challenge the report at the Licence Appeal Tribunal or in court, where its weaknesses can be exposed.

This is also why building your own strong medical evidence early — consistent treatment, specialist assessments and clear documentation — matters so much. A well-documented file makes a one-sided IME far less persuasive. You can read more about how evidence drives value in our settlement amounts guide.

The Bottom Line

An IME is a pivotal moment in an injury claim, and by default it is not on your side. The examiner is chosen and paid by the people who want to pay you less. That does not mean the appointment is something to fear — it means it is something to prepare for. Be honest, be consistent, describe your real limitations, and tell your lawyer before you attend so you walk in ready.
