Commercial Vehicle marking requirements — Quebec
Quebec registers heavy-vehicle owners/operators with the Commission des transports du Quebec (CTQ); the assigned NIR is the NSC number. Like Ontario CVOR this is a registered/carried credential - no verified exterior-display rule. Operator-name / NIR / unit-ID lettering is the practical fleet-identification need.
