Quick answer: You can cancel car insurance in Ontario at any time by telling your insurer or broker. Because you are the one cancelling, the refund is worked out on a “short rate” basis, which keeps back the insurer’s handling costs, and any minimum premium on your certificate is not refunded. If you are only parking the car for the winter, you usually don’t need to cancel at all: a suspension endorsement (OPCF 16) pauses most coverage while keeping theft and fire protection in place, if you carry it.

This guide walks through how cancellation works under Ontario’s standard auto policy, what it costs, and when suspending makes more sense. It is based on the Ontario Automobile Policy (OAP 1) owner’s policy used for policies on or after July 1, 2026, and on Ontario government guidance.

Can you cancel car insurance in Ontario at any time?

Yes. The standard Ontario owner’s policy says plainly that you may cancel your insurance at any time by advising your insurer. There is no fixed lock-in period for you as the policyholder.

The common reasons people cancel are:

• Switching to another insurer for a better price or coverage
• Selling the vehicle, or replacing it with another one
• Moving out of Ontario
• Taking a car off the road for a long period

Each of these has a slightly different “right way” to do it. The steps matter, because cancelling in the wrong order can leave you uninsured for a day or more.

How much does it cost to cancel car insurance in Ontario?

The cost depends on who ends the policy. The OAP 1 sets out two different methods.

So the “cancellation fee” people talk about is usually not a separate fee. It is the difference between a short-rate refund and a straight day-by-day refund. The exact amount depends on your insurer’s short-rate rules. Ask your broker for the dollar figure before you cancel, especially early in a policy term.

Refunds are paid “as soon as possible,” according to the policy wording. If your premium is subject to adjustment or reports are still pending, an insurer-initiated refund can take longer.

How to cancel car insurance in Ontario, step by step

1. Decide whether you really need to cancel. If the car is staying in your driveway or a garage for the winter, a suspension (see below) may cost less and keep theft and fire protection.
2. Line up your new coverage first. If you are switching insurers or buying another vehicle, confirm the new policy’s start date before ending the old one. The cancellation date should be the same day the new policy starts.
3. Ask for the numbers. Get the short-rate refund amount and any minimum premium in writing from your broker or insurer.
4. Give notice, and keep a record. The policy only requires you to advise your insurer, but an email or signed request gives you a dated record of when you asked.
5. Deal with the vehicle and plates. If you sold the car, remove your licence plates. Ontario uses a plate-to-owner system, so the plates stay with you, not the vehicle.
6. Watch for the refund and confirmation. Check that the cancellation date matches what you asked for, and that any pre-authorized payments stop.

If you pay monthly, stopping the payments is not the same as cancelling. Missed payments start the insurer’s non-payment process, described below, which can end with the insurer cancelling the policy itself.

Switching insurers: avoid a gap in coverage

Ontario has compulsory auto insurance. The Ministry of Transportation’s driver’s handbook says every vehicle registered in the province must be insured, and you must show proof of insurance to register or renew a registration. Your licence plate also only renews automatically if the vehicle has valid insurance.

That is why the order of steps matters. Start the new policy first, then cancel the old one effective the same date. Don’t cancel and “sort out the new one next week.”

If you are replacing your car, you may not need to cancel anything. Under the OAP 1, a newly acquired replacement vehicle gets the same coverage as the car it replaces, as long as you tell your insurer within 14 days of delivery and pay any extra premium. You must also tell your insurer when you sell or transfer a vehicle on your policy.

Before you switch, compare the coverage, not just the price. FSRA says that as of July 2026, only medical, rehabilitation and attendant care benefits remain mandatory; all other accident benefits are optional. Two quotes can look alike while covering very different things, so check our breakdown of which accident benefits to keep after the 2026 changes.

Storing your car for winter? Suspend instead of cancel

Late fall is when many Ontario drivers put a convertible, classic or second car away until spring. Cancelling outright leaves that vehicle with no coverage at all while it sits. The standard alternative is the OPCF 16 Suspension of Coverage endorsement, approved by Ontario’s regulator, the Financial Services Regulatory Authority of Ontario (FSRA).

Here is what the OPCF 16 does:

• Suspends third-party liability, accident benefits, uninsured automobile and direct compensation (property damage) coverage for the vehicle.
• Suspends collision or upset coverage, including the collision part of all perils coverage.
• Leaves in place the rest of your physical damage coverage, such as theft and fire protection, if you had comprehensive, specified perils or all perils coverage. (Our guide to car theft insurance in Ontario explains how a theft claim is paid.)
• Requires that the vehicle is taken out of use and not driven from the effective date.
• Pays no refund if coverage is suspended for fewer than 45 consecutive days.

When you are ready to drive again, coverage is restored with the OPCF 17 Reinstatement of Coverage endorsement. Ask for the reinstatement before the car moves, not after. During a suspension, the vehicle has no liability coverage, so even a short trip to the car wash is uninsured.

When can your insurer cancel your car insurance?

Insurers have less freedom to cancel than you do. Under the OAP 1:

• In the first 60 days, an insurer may cancel only for a reason it has filed with FSRA.
• After 60 days, it may cancel only for non-payment, false particulars about the vehicle, knowing misrepresentation or non-disclosure, or a material change in risk.

The insurer must also give written notice. How much notice depends on the reason and the delivery method:

The registered-mail periods start on the second day after the letter is mailed. For non-payment, the notice must tell you that you can keep the policy by paying what is owed, plus an administration fee, by noon on the business day before the last day of the notice period.

You have a matching duty: tell your insurer promptly about significant changes, such as a new driver in the household or a change in how the car is used. Failing to report changes can put claims at risk.

Should you call a broker before cancelling?

A broker can check the short-rate cost, set up an OPCF 16 suspension, or move you to a new insurer with matching start and end dates. Because a broker deals with several insurers, it can also tell you whether a suspension or a switch is the cheaper route for your situation.

If you are thinking of switching because of your renewal price, read our guide to car insurance renewal in Ontario first. Then use our checklist on how to compare auto insurance quotes in Ontario properly so the new policy actually matches the old one.

Frequently asked questions

Is there a penalty to cancel car insurance in Ontario?

There is usually no separate penalty line, but you get less back than the unused share of your premium. When you cancel, the Ontario owner’s policy says your premium is calculated on a short rate basis, which includes the insurer’s handling costs. Any minimum premium on your certificate is not refunded.

Can I cancel my car insurance in the middle of the term?

Yes. The standard Ontario Automobile Policy (OAP 1) lets you cancel at any time by advising your insurer. Ask for the refund amount first, and arrange replacement coverage if the vehicle is still registered and on the road.

How do I cancel car insurance in Ontario if I sold my car?

Tell your insurer or broker about the sale, as the policy requires, and ask them to end coverage on that vehicle from the sale date. Remove your licence plates before the buyer drives away, because Ontario plates belong to the owner, not the vehicle.

Do I need to cancel my insurance if I buy a new car?

Usually not. Under the OAP 1, a newly acquired replacement vehicle takes on the coverage of the car it replaces if you tell your insurer within 14 days of delivery and pay any extra premium. Your broker can then update the policy instead of cancelling it.

What is OPCF 16 in Ontario?

OPCF 16 is the Suspension of Coverage endorsement. It suspends liability, accident benefits, uninsured automobile, direct compensation and collision coverage for a vehicle that is taken off the road, while leaving other physical damage coverage such as theft and fire in place. No refund is paid if the suspension lasts fewer than 45 consecutive days.

How do I put my car insurance back after a suspension?

Ask your broker or insurer for the OPCF 17 Reinstatement of Coverage endorsement. It reinstates the coverages cancelled by the OPCF 16 from its effective date. Get it in place before the vehicle is driven, even for a short trip.

Can I drive my car while coverage is suspended?

No. The OPCF 16 requires that the vehicle is taken out of use and not operated, and its liability and accident benefits coverage are suspended. Driving it during a suspension means driving without the coverage Ontario requires.

Can my insurer cancel my car insurance in Ontario?

Yes, but only within limits. During the first 60 days an insurer can cancel only for a reason it has filed with FSRA; after that, only for non-payment, false particulars of the vehicle, knowing misrepresentation or non-disclosure, or a material change in risk. It must give written notice, for example 15 days by registered mail for reasons other than non-payment.

How much notice does an insurer give for non-payment?

The OAP 1 requires 10 days’ notice if delivered in person, by prepaid courier or electronically with your consent, or 30 days by registered mail. The notice must explain that you can keep the policy by paying what is owed plus an administration fee before the deadline.

Will my licence plate renew if I cancel my insurance?

Not automatically. Ontario’s plate renewal page says your licence plate renews automatically only if the vehicle has valid insurance and there are no outstanding fines or tolls. If you are keeping a vehicle registered, talk to a broker before cancelling.
