How to complete a supplementary vehicle registration — and autofill sr-lv-012 with my-id.ca
Register complex vehicle ownership without retyping registrant particulars
Buyers and registrants repeat legal names, addresses, driver's licence numbers, and company details on every Supplementary Application filed with vehicle registration. 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: Register a vehicle (permit and licence plate) — ontario.ca
- Form (Central Forms Repository): Supplementary Application — sr-lv-012
What this form is about
Form sr-lv-012 supplements vehicle registration when plates are owned by someone other than the vehicle owner, when registering to two individuals or companies, or when recording an unincorporated operating-as name — confirm which section applies on ontario.ca.
Before you start: what to gather
- Registrant legal name and address.
- Driver's licence or RIN for each registrant.
- Second registrant details if registering to two parties.
- Operating-as business name if section 3 applies.
Confirm the current process on ontario.ca.
