Understanding the Third Party Letter of Authorization for Vehicle Transactions in Ontario

If you need someone else to handle vehicle-related transactions on your behalf in Ontario, you may be required to provide a Third Party Letter of Authorization (LOA). This official form, issued by the King’s Printer for Ontario, ensures that a designated third party can legally act on your behalf for specific vehicle services. Here’s what you need to know about this essential document, how to complete it, and the steps involved.

What Is the Purpose of the Third Party Letter of Authorization?

The LOA authorizes a third party—such as a family member, friend, or authorized representative—to perform certain vehicle transactions on your behalf when you are unable to visit a ServiceOntario Centre personally. These transactions include renewing licenses, transferring vehicle ownership, changing vehicle data, and paying fines or fees. The form acts as a legal document that confirms your consent for the third party to act in your name for these specific tasks.

Who Should Fill Out the Form?

The vehicle or plate owner, or the driver requiring the transaction, must complete the form. Both the owner and the third party must sign it to validate the authorization. If the vehicle is jointly owned, both owners need to fill out their details. The third party must also present valid identification when submitting the form at ServiceOntario.

How to Complete the Third Party LOA

Section 1: Driver or Vehicle/Plate Owner Information

• Provide your full legal name as it appears on your driver’s license or vehicle ownership document.
• Write your address exactly as it appears on your identification.
• Include your driver’s license number or registration identification number (RIN).
• If applicable, fill in details about the vehicle, such as VIN, license plate number, make, model, year, and colour.

Section 2: Authorization Details

• Specify the transactions the third party is authorized to perform, such as renewing licenses, transferring ownership, or paying fines.
• The third party must present original or photocopied valid Ontario driver’s license or Ontario Photo Card, along with this LOA.
• If the transaction involves vehicle registration changes, the third party must also provide relevant vehicle documents.

Section 3: Signatures

Both the vehicle or owner and the third party must sign and print their full legal names. Signatures confirm that all parties agree to the terms outlined in the LOA and authorize the third party to act on your behalf for the specified transactions.

Required Documentation for Submission

When submitting the LOA at ServiceOntario, the third party must present:

• The original, signed Third Party Letter of Authorization.
• Valid original identification, such as an Ontario driver’s license or Ontario Photo Card, showing their full legal name, date of birth, and signature.
• For vehicle-related transactions, additional documents like vehicle registration or ownership documents may be required.

Where and How to Submit the Form

The original signed LOA must be presented in person at a ServiceOntario Centre; photocopies, faxes, or emails are not accepted. The third party should bring all necessary identification and vehicle documents related to the transaction. It is advisable to verify specific requirements for your transaction type on the ServiceOntario website or contact the centre beforehand.

Common Errors to Avoid

• Using photocopies or faxes instead of the original signed LOA.
• Leaving any section incomplete or using whiteout to correct errors—errors should be crossed out with a single line, and all parties initial beside.
• Failing to present valid identification or required vehicle documents.
• Not signing the form, which invalidates the authorization.

In summary, the Third Party Letter of Authorization is a vital document for delegating vehicle-related tasks in Ontario. Ensure it is correctly filled out, signed, and accompanied by valid identification to facilitate a smooth transaction process at ServiceOntario.
