To deregister your car in Ontario, remove your licence plates, sign over the vehicle ownership permit, and visit a ServiceOntario centre to cancel the vehicle registration in your name

Ontario currently has over 10.9 million registered motor vehicles on the road and thousands of those are deregistered or transferred every month due to sales, scrapping, or export, according to the Ministry of Transportation Ontario’s 2024 Road Safety Annual Report. For context, Statistics Canada reports that Ontario alone accounts for the largest share of vehicle registrations across all provinces, making proper deregistration a high-volume, legally critical process.

For example: if you are scrapping an old Honda Civic through a licensed scrap car removal Toronto service, you must remove your plates before the tow truck arrives and sign over the green ownership permit otherwise you remain legally tied to that vehicle even after it is crushed.

Deregistering a car in Ontario means officially removing yourself as the registered owner from Ministry of Transportation (MTO) records and surrendering or transferring the vehicle permit. It is a distinct process from cancelling your insurance; deregistration updates the province’s records, while insurance cancellation updates your insurer’s records. Both are required when permanently disposing of a vehicle.

This process becomes necessary in four main scenarios:

• The car is being scrapped at a licensed auto recycler or scrap yard
• The vehicle is sold to a private buyer, dealership, or scrap buyer
• The car is being permanently exported out of Ontario or Canada
• The vehicle has been written off by your insurer following a collision and will not return to the road

Understanding the difference between “selling” and “scrapping” matters here. When you sell a running car, ownership transfers to a new registered owner. When you scrap a car, the vehicle is permanently removed from circulation, and a Certificate of Destruction is issued. In both cases, the registration must be cancelled or transferred, and in both cases, your licence plates stay with you, not the vehicle.

Yes, in Ontario and across Canada, you are legally required to cancel or transfer a vehicle’s registration when it changes hands or is permanently taken off the road. While each province has its own process, Ontario’s Ministry of Transportation requires you to sign the back of the green vehicle ownership permit, detach your licence plates, and notify ServiceOntario of the change.

Failing to complete this process can have real financial consequences. Across Ontario, there were 10,963,505 registered motor vehicles as of 2024 with thousands of registration disputes, toll errors, and post-sale liability complaints stemming from improper deregistration each year. If your car is scrapped but still registered under your name, you could continue to receive 407 ETR toll bills, parking fines, and even insurance notices for a vehicle you no longer own.

From a Canada-wide perspective, Statistics Canada’s vehicle registration data confirms that Ontario experienced a 3.3% decline in active registrations in 2023, partly because drivers failed to renew or properly manage their vehicle records after the province changed its licence plate sticker policy in March 2022. This underscores how easy it is for administrative gaps to compound making it essential to take proactive steps when deregistering.

If you are scrapping your vehicle for cash, working with a reputable cash for scrap car service ensures the paperwork is handled correctly and you receive fair market value without legal loose ends.

Before visiting ServiceOntario or handing over your vehicle, gather the following:

• Green Ontario Vehicle Permit (Ownership) – both the vehicle portion (left side) and the plate portion (right side)
• Your Ontario Driver’s Licence or valid government-issued photo ID
• Certificate of Destruction – issued by the licensed auto recycler after the vehicle is scrapped
• Bill of Sale or receipt – from the buyer, dealer, or scrap car company
• VIN (Vehicle Identification Number) – must match exactly what is on the permit
• Lien release letter (if applicable) – confirms no outstanding financing on the vehicle. Check here for  clear 

Missing any of these can delay the process at ServiceOntario. If you have lost your vehicle ownership permit, you must apply for a replacement before proceeding with deregistration.

Step 1 – Settle All Outstanding Obligations

Before you cancel the registration of your car, clear all financial and legal ties to the vehicle. This includes:

• 407 ETR unpaid tolls – outstanding tolls are tied to the plate, not the driver, and will follow you until paid
• Parking fines or municipal tickets – unresolved fines can block a clean transfer at ServiceOntario
• Active liens or financing – contact your lender to confirm the lien is discharged; the PPSA (Personal Property Security Act) registration must be cleared
• Outstanding insurance claims – if the vehicle was in a collision, wait until the claim is fully settled before proceeding

This step is often skipped, and it is the most common reason deregistrations get delayed or rejected at the ServiceOntario counter.

Step 2 – Remove Your Licence Plates

This is the most critical physical step: remove your Ontario licence plates before the vehicle leaves your possession. In Ontario, licence plates belong to the registered owner, not the vehicle meaning your plates do not transfer with the car when you sell or scrap it.

Once removed, you have two options:

• Return them to ServiceOntario – heavy commercial vehicle owners (over 3,001 kg) may be eligible for a prorated credit or refund on remaining sticker validity
• Keep them for transfer to your next registered vehicle

Never leave plates on a scrapped vehicle. Fraudulent use of licence plates tied to your name can result in fines, insurance complications, and in severe cases, criminal liability.

Step 3 – Sign the Back of the Vehicle Ownership Permit

On the reverse side of the green ownership permit, complete all required fields:

• Buyer’s full name and address (or scrap company’s registered business name)
• Date of sale or transfer
• Odometer reading at time of sale
• Your signature as the seller/transferor

Do not leave any field blank incomplete permits will be rejected at ServiceOntario. If selling to a licensed scrap removal service like Scrap Car Buyer Toronto, confirm their registered business name before filling in the buyer field to ensure accuracy.

Step 4 – Visit a ServiceOntario Centre

Bring the signed ownership permit and your photo ID to your nearest ServiceOntario location. Request that the vehicle status be updated to “sold” or “scrapped” and formally removed from your name. This is the step that legally completes the vehicle registration cancellation in MTO records.

ServiceOntario has over 300 locations across Ontario, making in-person visits accessible for most residents. You do not typically need an appointment for a registration transfer or cancellation.

If you are working with a licensed scrap car removal Toronto company, ask whether they handle the MTO transfer on your behalf, many reputable operators do, saving you the trip entirely.

Step 5 – Obtain and Keep a Certificate of Destruction

If your vehicle is being scrapped, the licensed auto recycler is legally required to issue a Certificate of Destruction (also known as a salvage certificate in some contexts). This document confirms:

• The vehicle has been permanently decommissioned
• The VIN is retired from the road
• The recycler has accepted legal responsibility for the vehicle’s disposal

Request a copy for your records and keep it for a minimum of two years. This protects you in case of any post-scrapping disputes, insurance inquiries, or MTO discrepancies.

Step 6 – Cancel Your Auto Insurance

Once the vehicle is officially deregistered and the Certificate of Destruction is in hand, contact your insurance provider to cancel the policy on that vehicle. Many insurers will issue a prorated refund for unused premiums. Failing to cancel insurance on a scrapped or sold vehicle means paying for coverage on a car you no longer own, an unnecessary expense that affects thousands of Ontario drivers annually.

Step 7 – Confirm the MTO Record Update

After completing the above steps, verify with ServiceOntario that:

• The vehicle is removed from your name in MTO records
• Your plate status has been updated (returned, retained, or transferred)
• You hold copies of all signed documents

Keep everything on file for at least two years as a safeguard.

When it comes to returning licence plates in Ontario, most passenger vehicle owners simply retain their plates for use on a future vehicle. However, certain vehicle categories are eligible for a refund or credit on remaining plate sticker fees when plates are returned.

Here is a breakdown of what you need to know:

• Passenger vehicles, light commercial vehicles, motorcycles and mopeds: Ontario eliminated the annual licence plate sticker renewal fee for these categories in March 2022, so there is currently no sticker fee to refund for most private drivers
• Heavy commercial vehicles (over 3,001 kg): You can request a prorated refund or credit on any remaining sticker validity. Visit a ServiceOntario centre with your plates and original vehicle permit
• Snow vehicles: Eligible for a refund on remaining snow vehicle validation when returning plates

Returning your plates in person is the required method as of 2026, Ontario does not offer a fully digital online licence plate return process. Bring the physical plates and the plate portion (right side) of your green vehicle ownership permit to any ServiceOntario location.

For heavy commercial vehicle owners in Southern Ontario, the annual sticker fee was $120 per year (or $240 for two years), while Northern Ontario rates were $60 per year, making the prorated refund on remaining months genuinely worth claiming.

This is one of the most searched questions on this topic, and the honest answer is: partially, but not fully.

Ontario’s ServiceOntario platform allows some vehicle-related transactions online (such as address changes and certain renewals), but the formal cancellation or transfer of vehicle registration  especially for scrap or sale still requires an in-person visit or mail submission in most cases. The exception is address changes on your vehicle permit, which can be done at Ontario.ca.

What you can do online before visiting ServiceOntario:

• Verify your vehicle permit and plate information via MTO’s online portal
• Update your mailing address to ensure documents reach you
• Check for outstanding fines and tolls using the 407 ETR portal or municipal websites
• Confirm lien status on the PPSA registry

Scrap removal companies that handle MTO paperwork on your behalf (such as licensed operators offering cash for scrap car services) can further reduce the administrative burden, completing the in-person steps for you.

Even informed Ontario drivers make avoidable errors during deregistration. Here are the most common pitfalls:

Leaving plates on the vehicle – the single most frequent and costly mistake; your plates can be used fraudulently after the car leaves your possession

Not clearing tolls before transfer – 407 ETR debts follow the plate owner, not the vehicle; resolve these first or ServiceOntario may flag the registration

Signing an incomplete ownership permit – blank fields on the back of the green permit are grounds for rejection; fill in every section clearly

Skipping the Certificate of Destruction – without this document, your liability for the vehicle is ambiguous; always request it from the scrap operator

Assuming the scrapper handles everything – even if a licensed company takes the vehicle, you are responsible for removing plates and providing a properly signed ownership permit

Forgetting to cancel insurance – a scrapped vehicle still on your insurance policy costs you money and may cause complications in future claims

Using an outdated permit copy – if your ownership has been replaced, updated, or re-issued, ensure you are using the most current version

The steps are straightforward: clear outstanding debts, remove your licence plates, sign the green ownership permit, visit ServiceOntario to formally cancel the registration, and secure your Certificate of Destruction if scrapped. Every step you skip is a potential liability left open in your name.
