What is distinct in Quebec
Quebec's immatriculation, contrôle mécanique, heavy-vehicle owner/operator and spring-thaw systems use distinct authorities and official French terminology.
Ownership and registration
La Société de l'assurance automobile du Québec (SAAQ) administers immatriculation and ownership-related vehicle services. Preserve the official French program names when no equivalent official English title is provided.
Out-of-province and inspection
Use SAAQ contrôle mécanique guidance to determine inspection type and authorized facility requirements.
Weights, dimensions and permits
Use Québec transport and permit sources for charges, dimensions, axle loads, thaw restrictions and special movement.
Carrier obligations are separate
Commission des transports du Québec and SAAQ responsibilities for heavy-vehicle owners/operators can apply separately from transfer.
Buyer document file
Confirm seller authority, ownership documents, lien-search direction, VIN/build evidence, service history, inspection status, import status where relevant and written representations. Ask the authority which originals and forms are required.
