Where must the mandatory mechanical inspection be carried out?

You have to make an appointment at one of our mechanical inspection centres to have the mechanical inspection carried out by an authorized mechanic.

For the mechanical inspection, the vehicle must be unloaded and free of any dirt or obstructions that could hamper the proper inspection of all components.

If the vehicle is compliant: inspection sticker

If all the vehicle's components are compliant, an inspection sticker is affixed to the vehicle.

If a defect is found: mandatory repairs

If a defect is found, the owner must have all the necessary repairs made to obtain the inspection sticker.

Minor defect

In the case of a minor defect, a 48-hour deadline is granted to have the repairs made and obtain the inspection sticker. Past that deadline, the vehicle may not be operated.

Major defect

In the case of a major defect, the vehicle is immediately prohibited from road use. The vehicle must be repaired and given an inspection sticker before being authorized for road use.
