Quebec has stricter rules regulating the search of license plate numbers than other Canadian provinces. The Société de l'Assurance Automobile du Québec or SAAQ is the government agency in charge of licensing vehicles and providing public auto insurance. To check Quebec license plate numbers legally you will have to provide a good reason or have the authorization of the owner to do so.
Step 1
Request the information from the vehicle's owner. For example, if you are buying a car from a stranger, the easiest way to confirm the identity of the seller is to ask for official documents that link him to the car's license plate number.
Step 2
Contact the Société de l'Assurance Automobile du Québec. Request the information you need on a license plate number. For instance, it can check a vehicle for any pending liens and traffic fines before you buy it. You can contact the SAAC by phone, email or mail. Up-to-date contact details are available at its homepage (see References).
Step 3
Call the Sûreté du Québec, the police force of the Canadian province, and request the information you need. Again, you may have to provide additional documentation and a reason for requesting the information. The Sûreté du Québec provides a list of police stations and contact details at its homepage (see References).
Step 4
Talk to a private investigator. If you can't or do not want to do it yourself, you can hire an private investigator to check Quebec license plate numbers. However, according to online private investigation company Best People Search, if you are searching for license plates in Quebec, you must provide the vehicle's identification number, or VIN.
Warning
Searching for personal information without the necessary authorization can be illegal. You can also be held responsible for the actions of a private investigator in your employ.
