What a medical suspension means for your Ontario license
A medical suspension is when the Ontario Ministry of Transportation (MTO) removes your driving privileges because of a medical condition or medication that affects your ability to drive safely. Unlike a suspension for traffic violations, a medical suspension happens because the MTO has concerns about your health — not because you broke a rule. The suspension stays in place until you provide medical documentation showing the condition is managed or resolved.
The MTO can suspend your license based on information from your doctor, a hospital, or even a police officer who suspects a medical issue. You do not have to be convicted of anything or charged with a crime. The MTO's job is to keep unsafe drivers off the road, and they take medical concerns seriously.
Key Takeaways
- The MTO can suspend your license if your doctor reports a medical condition affecting driving safety, and you will be notified by mail with the reason.
- You can request a medical review hearing to challenge the suspension, but you must do so within a specific timeframe or the suspension becomes permanent.
- To lift the suspension, you typically need a letter from your doctor stating your condition is controlled and you are safe to drive.
- Some conditions (like untreated epilepsy or severe dementia) may result in a permanent suspension unless the condition resolves.
- If you drive while suspended for medical reasons, you face fines, a longer suspension, and possible criminal charges.
How the MTO finds out about a medical condition
Doctors in Ontario are required by law to report certain medical conditions to the MTO if they believe the condition makes driving unsafe. These reports are confidential, but they trigger an investigation. Common conditions that get reported include untreated seizure disorders, severe dementia, uncontrolled diabetes, serious heart problems, and conditions affecting vision or coordination.
A police officer can also report you if they suspect a medical issue during a traffic stop. Hospitals sometimes report patients who have had strokes, heart attacks, or serious injuries. You might not know a report has been made until you receive a letter from the MTO.
The MTO may also ask your doctor directly for information about your condition if they have reason to believe your license should be reviewed. This happens through a form called a medical examination report, which your doctor completes and sends back to the MTO.
What happens when the MTO suspends your license
You will receive a letter in the mail from the MTO explaining that your license is suspended and why. The letter will include the date the suspension takes effect and information about your right to request a hearing. Read this letter carefully — it contains important date you must meet.
Your physical license remains valid until the suspension date, but you cannot legally drive after that date. If you are caught driving while suspended for medical reasons, you face a fine of $500 to $1,000 for a first offense, and the suspension period gets extended. A second offense within five years can result in a fine up to $2,000 and possible jail time.
The suspension is not automatic punishment — it is a safety measure. The MTO believes you are not safe to drive right now, but the door is open to prove otherwise through medical documentation.
Requesting a medical review hearing
You have the right to challenge a medical suspension by requesting a hearing before the Licence Appeal Tribunal (LAT). This is a formal process, but it is your main chance to keep your license or get it back sooner. You must request the hearing within 30 days of receiving the suspension letter — if you miss this important date, the suspension becomes permanent and you lose the right to a hearing.
To request a hearing, contact the LAT directly. You can find their contact information on the MTO website or in your suspension letter. Tell them you want to appeal a medical suspension and provide your license number and the date of your suspension letter.
At the hearing, you will present evidence that you are safe to drive. This usually means bringing a letter from your doctor stating that your condition is now controlled or resolved, and that you are medically fit to drive. You can also bring medical test results, a record of treatment, or other documentation. The tribunal member will ask you questions and may ask your doctor to explain their findings.
Getting your license back after a medical suspension
The most common way to lift a medical suspension is to provide the MTO with a letter from your doctor. The letter should state that your medical condition is now managed, controlled, or resolved, and that you are safe to drive. Some doctors use a specific form provided by the MTO for this purpose.
Send this letter to the MTO at the address listed in your suspension letter. Include your license number and the date of your suspension. The MTO will review the letter and may ask for additional information or request that you see a doctor of their choosing for a second opinion.
If your condition improves on its own or with treatment, you can reapply for your license once you have medical clearance. If your condition is permanent or unlikely to improve, the MTO may not lift the suspension. In that case, you would need to explore other transportation options or wait to see if your health changes.
Conditions that may result in a permanent suspension
Some medical conditions are so serious that the MTO may not lift the suspension even if you provide medical documentation. These include untreated epilepsy or seizure disorders, severe dementia or Alzheimer's disease, and complete loss of vision. If you have one of these conditions, a permanent suspension is possible unless the condition resolves (which is unlikely for many of them).
A permanent suspension does not mean you can never drive again — it means you cannot drive until the condition changes significantly. If you recover or your condition improves substantially, you can request a new hearing and provide updated medical evidence.
Even with a permanent suspension, you may be able to work with the MTO and your doctor to explore options. Some people pursue specialized training or adaptive equipment that might allow them to drive safely despite their condition. This is rare and requires strong medical support, but it is not impossible.
What to do if you receive a suspension letter
First, do not ignore the letter. Read it completely and note the suspension date and the important date for requesting a hearing (usually 30 days). If you disagree with the suspension or believe your condition has improved, contact the LAT when ready to request a hearing.
Second, contact your doctor. Explain the suspension and ask whether your condition is now controlled or whether you are safe to drive. If your doctor agrees you are safe, ask them to write a letter to the MTO stating this. Provide them with the MTO's address and any specific form the MTO uses for medical clearance.
Third, gather any medical records that support your case — test results, treatment records, medication lists, or specialist reports. Bring these to your hearing if you request one.
If you cannot drive, arrange alternative transportation. Use transit, carpool, or ask family for rides. A medical suspension is temporary in many cases, and having a plan for the suspension period makes it easier to manage.
Frequently Asked Questions
Can I drive while waiting for my hearing?
No. Once the suspension takes effect, you cannot legally drive, even if you have requested a hearing. Driving while suspended for medical reasons is a criminal offense in Ontario. Wait for the hearing outcome or for the MTO to lift the suspension based on medical documentation.
What if my doctor disagrees with the MTO's decision to suspend my license?
Bring your doctor's opinion to your hearing. The tribunal will consider what your doctor says about your condition and your ability to drive safely. If your doctor's assessment differs from the MTO's concerns, present that evidence clearly at the hearing.
How long does a medical suspension usually last?
It depends on the condition and how quickly it improves. Some suspensions last a few weeks if the issue resolves quickly. Others last months or longer. If you provide medical clearance promptly, the MTO may lift the suspension within a few weeks of receiving the letter.
Do I have to pay a fee to request a hearing?
Yes. The Licence Appeal Tribunal charges a fee to request a hearing. The fee amount varies, so check the LAT website or your suspension letter for the current cost. This fee is separate from any costs related to getting medical documentation.
What if I cannot afford a doctor's letter to clear the suspension?
Contact your family doctor or a clinic that offers low-cost services. Explain that you need a medical letter for a license suspension. Some doctors will provide this at no extra charge if you are already a patient. Community health centers may also help at reduced cost.
