How to authorize someone to act on your MTO account — and autofill the form with my-id.ca
Authorize a third party for your driver's licence records without retyping your details
If you want someone else to access your driver's licence or vehicle records at ServiceOntario on your behalf, the third party authorization repeats your name, address, and the authorized person's details. This guide is an example of storing them once in my-id.ca.
Official form and source
Start from the official source and always use the current version — form numbers and links can change:
- Service page: Renew your driver's licence — ontario.ca
- Form (Central Forms Repository): Third Party Letter of Authorization — 023-sr-ld-433
What this form is about
This letter authorizes a third party to act on your behalf for specified Ministry of Transportation transactions — such as renewing a licence or updating records at ServiceOntario.
Before you start: what to gather
- Your full legal name and current address.
- Your driver's licence number.
- The authorized person's full name and address.
- What they are authorized to do on your behalf.
Confirm the current process on ontario.ca.
