MTO Audit Ontario Commercial Vehicles | Compliance Lettering
MTO Audit Ontario Commercial Vehicles — regulation-compliant, made in Canada. Same-day production on 7-year outdoor vinyl, ships nationwide.
Is Your Commercial Vehicle Actually Legal?
Most HVAC, plumbing, roofing, and electrical trucks on Ontario roads are running with non-compliant lettering right now. MTO roadside inspectors check it at every stop — and they will write you up.
Ontario Reg 424/97 requires: CVOR number displayed on both doors, minimum 50mm (2") tall, in contrasting colour, matching your registered operator name exactly. Wrong size, wrong name, or missing — that's a fine plus a CVOR safety rating hit that raises your insurance.
📋 Regulatory Snapshot
| Specification | Requirement | Legal Reference |
|---|---|---|
| CVOR Number Height | 50mm (2") minimum | O.Reg 424/97 s.10 |
| Operator Name | Must match CVOR certificate exactly | NSC Standard 10 |
| Placement | Both sides of vehicle, near rear of cab | HTA s.16 |
| Colour Contrast | Must contrast with vehicle background | O.Reg 424/97 s.10(1)(b) |

MTO officers at Vineland, Fort Erie, and Port Hope scales check door lettering on every commercial stop. A violation is logged against your CVOR safety rating — affecting your insurance premiums and your ability to operate. First offence is a monetary fine. Repeat violations risk your carrier licence.
