Understanding the Ontario RIN (Registrant Identification Number): Complete Guide for Businesses
What Is a RIN in Ontario?
A RIN (Registrant Identification Number) is a unique business identifier issued by the Ontario Ministry of Transportation (MTO).
It is used to register and own vehicles under a business or corporate name rather than an individual’s driver’s licence number.
In short:
A RIN allows your company, partnership, or organization to legally own, lease, buy, or sell vehicles in Ontario. If your business buys or transfers a vehicle, you must have a valid RIN before completing the transaction at ServiceOntario.
Who Needs a RIN?
You need a RIN if your organization:
• owns or leases commercial or fleet vehicles in Ontario; • registers a vehicle under a company name; • buys or sells vehicles through a business rather than personally; or • operates a corporation, partnership, or numbered company that appears on a vehicle permit.
Even small businesses and sole proprietors require a RIN if they plan to register vehicles under their business name instead of their own.
How to Get a RIN in Ontario
There are two official ways to obtain a RIN:
Option 1: Complete the RIN Application Form
Businesses can apply for a RIN by filling out a Business Information Form through ServiceOntario.
You’ll need:
• Your business name and address • Ontario Business Number (BN) or Master Business Licence • Identification for the authorized signing officer • Proof of incorporation or registration
After submission, ServiceOntario issues your RIN and adds it to the MTO’s business ownership database.
Option 2: Swear a RIN Declaration (Commissioned or Notarized)
If you prefer a guided route, you can complete a RIN Declaration Form, which is a sworn statement confirming:
• Your authority to act on behalf of the business • The legal existence of the business entity • The intent to register or transfer ownership of a vehicle
The declaration must be sworn before a lawyer, notary public, or commissioner for taking affidavits.
This process is often used by small businesses or entrepreneurs who need special assistance with the process.

Why the RIN Is Important for Businesses
The Registrant Identification Number acts as the business’s official vehicle ownership identity.
It ensures:
• The vehicle is legally owned by the business, not an individual • Corporate vehicles can be insured and transferred properly • Business continuity even if directors or officers change
Without a valid RIN, your business cannot appear as a vehicle owner, which can delay purchases, sales, or fleet registrations.
Common RIN Mistakes (and How to Avoid Them)
1. Using a personal driver’s licence number for a business vehicle 2. Failing to update the RIN when the business address or name changes 3. Missing signatures or unsworn declarations 4. Submitting incomplete documentation to ServiceOntario
Tip: Always verify that your RIN matches your current business registration and that any declaration you use is properly sworn.
