RIN Letter

There is a broad range of reasons why businesses need access to automobiles. This creates a legal problem for corporations, partnerships, and sole proprietorships since they are considered to be “different persons” under the law. A company or corporation can own a car but cannot get a license to legally operate the vehicle.

Ontario addresses this issue by assigning a unique identifier to each company and corporation that owns a vehicle. The unique identifier is known as the RIN (Registrant Identification Number).

The provincial government of Ontario appoints notaries public to perform a range of official duties including the notarization for RIN letters. If you need a RIN letter prepared or if you already have the RIN letter and just need it notarized, contact The Notary Guy today!

How can I know whether I need a RIN letter (sworn statement)?

Vehicle registration in the name of a company in Ontario is presently impossible without a notarized letter, as required by the Ministry of Transportation (via Service Ontario).

If you need to update the address associated with a business vehicle registered under an existing RIN, you may additionally be asked to provide a notarized letter requesting for the change in business/registration address.

Process of RIN letter

Here are the 3 steps you need to follow to have your RIN letter ready:

      • Look for your company’s incorporation papers, DBA registration, or master license. At least two (2) pieces of corporate mail, such as a corporate tax return, utility bill, leasing agreement, insurance policy, etc., with the company’s name and registered address.

        • A formal RIN Letter that has been signed and sealed by a notary public. A statutory declaration requires the notary public to confirm your identification, authenticate the business papers, and attach the official notary seal
        • Locate the closest Service Ontario office in your area to have the RIN made or drop-off all the paperwork including the RIN letter with your authorized car dealer that will be registering the vehicle.

          A Registrant Identification Number (RIN) is a number assigned to a business by ServiceOntario, which is needed when registering a vehicle in Ontario to get a vehicle permit, license plate, and license plate sticker for said business. It is a unique 9-digit number that is used by corporations to register a vehicle with the Ontario Ministry of Transportation.

          To obtain your Registrant Identification Number (RIN) in Canada, you need to have proof of your business address, fill a RIN form (available at all Service Ontario centers), and have a Notarized letter of Authorization filled by someone with the authority to bind the organization (such as the CEO or Director). 

          All vehicles in Ontario need to be registered to be driven on the road, and businesses need vehicles for a variety of reasons. Corporations that want to register a vehicle cannot obtain a driver’s license because they cannot physically drive a vehicle, and for this reason, the Ontario government created the RIN to differentiate business-owned vehicles in the motor vehicle registration system. This allows vehicles for work purposes to be registered to a business. 

          Once created, a RIN can be re-used to register multiple vehicles belonging to a single business so there’s no need to create multiple ones.

          Corporate and business vehicles need a RIN, as each car on road needs legal identification and authorization of the government of Canada.
