How to Sell a Car in Ontario Using a Power of Attorney

Published on Jun 23, 2025 | Last updated Aug 6, 2026

Introduction

Selling a car can be stressful, especially when you can’t be present for the transaction in person. In Ontario, you are legally allowed to use a power of attorney (POA) to make the process easier. This guide explains how to sell a vehicle using a power of attorney (POA), which documents you will need, and how to avoid common mistakes.

This guide also covers ownership transfer, vehicle registration, and the seller’s responsibilities. It also explains how to sell a car using a POA in Ontario, listing the required documents, exact steps, and ways to avoid common mistakes.

What Is a Power of Attorney?

A power of attorney is a legal document that lets another person act on your behalf regarding property, finances, or personal care. In Ontario, the two primary types are:

  1. Continuing Power of Attorney for property: Allows someone to manage your financial affairs, including selling your vehicle.
  2. Power of Attorney for Personal Care: This covers medical and personal care decisions and cannot be used to sell a vehicle.

To sell a car, the agent must have a valid continuing POA for property, and the document must allow them to sell the vehicle.

When Would You Use a Power of Attorney to Sell a Car?

For example, imagine that someone from Scarborough moves to Alberta for work but leaves an older vehicle behind. Instead of returning to Ontario to complete the sale, the owner could authorize a family member through a continuing power of attorney for property to handle the transaction.

There are many situations where it makes sense to let someone else handle the sale of your car:

  • You are out of the country or out of the province
  • You are unable to leave your home because of an illness, an injury, or other personal reasons
  • You simply do not have the time to deal with all the work of the sale and paperwork
  • You want someone else to handle the sale of your car, including transferring the ownership or returning the licence plates.

Creating a Power of Attorney to Sell a Car in Ontario

A Power of Attorney must meet Ontario’s legal requirements to be valid:

  1. Be in writing (per Ontario’s Substitute Decisions Act, 1992).
  2. Authorize the agent to sell your vehicle and transfer ownership.
  3. Be signed by the vehicle owner in the presence of two witnesses.
  4. Include the names of both the owner and the agent, along with the vehicle’s make, model, year, and VIN.

What Documents Will The Agent Need To Carry?

In our experience, one of the most common reasons a sale is delayed is missing paperwork. People often assume that the ownership permit alone is enough, only to discover that they also need the Used Vehicle Information Package (UVIP) and other documents before the transfer can be completed.

If the agent sells the car on your behalf, they will need to bring the following documents: 

  • The original signed power of attorney document
  • A piece of their own valid government-issued photo identification
  • A copy of the seller’s identification
  • Vehicle Ownership Permit
  • Used Vehicle Information Package (mandatory in Ontario)
  • Ontario Safety Standards Certificate (if vehicle is being sold for regular use on the road)
  • Bill of Sale stating the transaction
  • Any emissions test results (if applicable).

Can ServiceOntario Refuse a Power of Attorney?

Yes. ServiceOntario may refuse a power of attorney if the document is incomplete, improperly signed, contains unclear wording, or does not specifically grant authority to sell the vehicle. If you are unsure, it is a good idea to contact ServiceOntario before starting the sale.

Steps to Sell a Car in Ontario with a Power of Attorney

This is a simple outline of how the sales process works:

  1. Find Buyer: The agent will assist in listing the vehicle and meeting potential buyers
  2. Verify the Buyer: Ask for a valid government-issued ID before moving forward.
  3. Provide UVIP: It is a requirement in Ontario that the seller (or your agent) presents the UVIP to the buyer before the sale.
  4. Vehicle inspection and test drive: The buyer may want to inspect the vehicle and drive it.
  5. Agree on Price: Agree on the sale price and payment method.
  6. Create the Bill of Sale: The bill of sale should clearly show both your name and your buyer’s name and addresses, as well as the sale price, date of sale, and VIN.
  7. Sign Required Paperwork: The agent will sign the bill of sale and the other paperwork for you, clearly indicating in each case ‘acting as power of attorney.’
  8. Remove Licence Plates: In Ontario, your licence plates stay with you, not with the car.
  9. Provide Documents to the Buyer: Give the buyer the bill of sale, signed ownership permit, UVIP, and safety certificate (if applicable).
  10. Submit the required documents to ServiceOntario: Your agent can help you file the important transfer paperwork and return/transfer your license plates.

What Happens to the License Plates?

In Ontario, the license plates are registered to the owner, not the car. After a sale:

  • The agent must remove the plates before transferring the car to the buyer.
  • The agent can either return the plates to a ServiceOntario office or claim any unused months as a refund.
  • If the seller has another car, they could transfer the plates to it.

Avoiding Common Pitfalls

We have also seen situations where family members believed a handwritten note would be accepted as proof of authority. In reality, ServiceOntario may refuse incomplete or improperly prepared documents, which can delay the transfer process.

Here are a few common mistakes people make when giving a POA to someone to sell a car:

  • Invalid or incomplete POAs: If the document isn’t worded correctly or signed with the required witness signatures, ServiceOntario will not accept it.
  • Forgetting documents: If you have not gathered the required documents (the UVIP, ownership permit, and bill of sale), the sale process may be delayed.
  • Not removing plates: Failing to remove the licence plates could create problems after the sale.
  • Safety inspections: If the buyer intends to drive the vehicle immediately after the sale, a valid safety certificate is required.

Cancelling or Transferring Insurance

After the sale is complete:

  • Contact your insurance company to cancel or transfer coverage.
  • If you have other vehicles, you may be able to transfer coverage.
  • Your insurance agent can also help you return the licence plates and confirm cancellation with ServiceOntario.

Tax and Financial Responsibilities In Ontario:

  • The buyer will pay the Retail Sales Tax (RST) on the value of the vehicle at the time of ownership transfer.
  • The seller is not responsible for paying any taxes on the sale of the vehicle.
  • The vehicle must be free of any liens before the sale; any existing lien will appear in the UVIP.

Post-Sale Actions

Now that the transaction is complete, the agent will:

  1. Verify that the ownership has been transferred at ServiceOntario.
  2. Remove the license plates and return or transfer them.
  3. Inform the insurance company.
  4. Retain copies of the bill of sale and any transfer receipts.

Conclusion

Selling a vehicle in Ontario using a power of attorney is possible, but care is required. The agent will need a properly executed power of attorney, identification, and the paperwork for the vehicle to ensure the sale proceeds easily. Overlooking small details—like removing license plates or canceling insurance—can lead to legal or financial complications. Ensuring these tasks are completed correctly will help you avoid unnecessary legal or financial problems after the sale.

If your vehicle is old, damaged, or no longer drivable, Greenway Auto Recycling can help you remove it legally while taking care of the paperwork. The Greenway Auto Recycling team picks up scrap vehicles, removes your plates, and assists you in completing your paperwork correctly. This is a safe, straightforward way to get rid of an unwanted vehicle without extra work.

One thing we have learned over the years is that checking the paperwork twice before meeting the buyer can save a great deal of time and frustration.
