Registering a Vehicle

Before registration

Step 1 Before registration

To register a trailer to a business

The business must be registered with the Registraire des entreprises (enterprise register) because you need to provide your Québec enterprise number (NEQ) to register your trailer.

If the trailer has a gross vehicle weight rating of 4,500 kg or more

Registration in the Registre des propriétaires et des exploitants de véhicules lourds (register of owners and operators of heavy vehicles)

You must be registered in the register of owners and operators of heavy vehicles of the Commission des transports du Québec (CTQ):

  • if the trailer has a gross vehicle weight ratingA vehicle's weight, including its maximum load capacity, according to the manufacturer's specifications. of 4,500 kg or more
  • If the trailer and the towing vehicle have a gross vehicle weight rating of 4,500 kg or more

However, if you use the trailer for personal purposes, you do not have to register with the CTQ.

If you are purchasing a trailer without being registered with the CTQ, you can still register your trailer, but you cannot put it into operation.

Mechanical inspection

If the trailer is used, the most recent mechanical inspection must have been performed within the past 12 months, or within the past 6 months for trailers used by a driving school. You must present a valid mechanical inspection certificate when you register your trailer.

The trailer cannot be registered…

If the buyer or the seller has an unpaid fine for an offence under the Highway Safety Code or a municipal traffic or parking bylaw.
