Ontario Commercial Vehicle Annual Inspection Requirements
Every commercial vehicle in your Ontario fleet must pass an annual inspection at a licensed station. An expired sticker is an immediate out-of-service condition — and a single expired certificate in your fleet is a critical audit finding.
Direct answer
Every Ontario commercial vehicle must pass an annual inspection at a licensed Motor Vehicle Inspection Station (MVIS). The requirement is governed by Ontario Regulation 611 and NSC Standard 11, Part B (Periodic Motor Vehicle Inspection). A passed vehicle receives an inspection sticker valid for 12 months (certain bus classes require semi-annual inspection). An expired sticker is an immediate out-of-service condition at any roadside check.
The Legal Requirement
Annual commercial vehicle inspections in Ontario are governed by Ontario Regulation 611 (Safety Inspections) under the Highway Traffic Act. O. Reg. 174/22 specifies which vehicle classes require annual inspection and which require the more frequent semi-annual cycle.
The technical inspection standard follows NSC Standard 11, Part B — the Periodic Motor Vehicle Inspection standard. This is distinct from Part A, which governs preventive maintenance programs. Part B governs the periodic inspection itself: what must be checked, the pass/fail criteria for each component, and the certification requirements.
Who Can Inspect
Annual commercial vehicle inspections must be performed at a licensed Motor Vehicle Inspection Station (MVIS). The station must hold a current MTO MVIS licence for the class of vehicle being inspected. The technician performing the inspection must hold an appropriate MTO certificate of qualification.
A carrier's internal maintenance shop can legally perform annual inspections — only if the shop holds an MVIS licence and employs certified inspectors for that vehicle class. Having a certified mechanic on staff is not enough. The station designation requires the physical facility and tooling to meet MTO requirements, and it must be licensed separately.
Carriers who use external inspection stations should verify that the station's MVIS licence is current and applicable to their vehicle class before scheduling inspections. A certificate issued by an unlicensed facility does not satisfy the requirement.
Inspection Validity and Semi-Annual Requirements
Annual Cycle (12 months)
Most commercial vehicles including trucks, tractors, and trailers. Inspection certificate is valid for 12 months from the date of inspection. The sticker affixed to the vehicle shows the expiry month and year.
Semi-Annual Cycle (6 months)
Certain bus classes and specific vehicle types under O. Reg. 174/22. Carriers operating buses should confirm which cycle applies to each vehicle in their fleet — the semi-annual requirement is specific to certain passenger-carrying configurations.
What the Annual Inspection Covers
The NSC Standard 11B inspection is a comprehensive mechanical review of every safety-critical system on the vehicle. Unlike a DVIR — which is a driver's visual walkaround — the annual inspection requires physical measurement, component testing, and technical assessment.

Record-Keeping Requirements
The inspection certificate issued upon a passed annual inspection must be retained by the carrier. The sticker on the vehicle is not the record — it is a roadside indicator. The paper certificate in your file is the document an auditor will review.
Carriers must maintain inspection certificates for the required retention period for each vehicle in the fleet — including vehicles that have since been sold or taken out of service, for the period they were in operation. This matters at audits: an auditor may ask to see inspection records for a vehicle that is no longer in your fleet.
Most carriers keep inspection certificates in each vehicle's file — alongside the DVIR binder, PM records, and registration documents. Organization matters here: an auditor who cannot quickly locate a certificate will note the absence, even if the certificate technically exists somewhere.
Why One Expired Certificate Is a Serious Audit Finding
In fleet operations it is easy to focus on the vehicles that are due soon and miss the one that slipped through. But the consequences are disproportionate: in a facility audit, one expired annual inspection certificate on any vehicle is a critical deficiency in the maintenance profile. It does not matter that your other twelve trucks are current.
At roadside, an expired annual inspection certificate is an immediate out-of-service condition. The vehicle does not move until a current certificate is obtained — meaning an unplanned stop, potential cargo disruption, and an entry in your Commercial Vehicle CVOR category.
Critically defective commercial vehicles identified at roadside are subject to impoundment for a minimum of 15 days. Operating a vehicle with an expired inspection sticker is not a critically defective designation by itself — but if the inspection reveals a major defect that has developed since the last certificate, the outcome changes significantly.
Cross-Province Recognition
Ontario recognizes current annual inspection certificates issued by other Canadian provinces and territories. A vehicle with a current out-of-province inspection sticker does not need to obtain an Ontario inspection to operate in Ontario — as long as the certificate has not expired.
CVSA Decals — issued during CVSA-level roadside inspections when a vehicle passes at North American Out-of-Service standard — are also generally recognized across jurisdictions as evidence of recently confirmed roadworthiness, though they do not replace the annual inspection requirement.
Practical tracking recommendation
Maintain an expiry calendar for every vehicle in your fleet — annual inspection, registration, and insurance. Schedule inspections 30 days before the expiry date to allow time for repairs and re-inspection if the vehicle does not pass on the first attempt. One failed inspection is not a problem. One expired certificate at roadside is.
