Ministry of Transportation (MTO) - Sarnia Commercial Vehicle Inspection Facility (CVIF)

Ministry of Transportation Enforcement Officers (TEOs) enforce a variety of provincial highway safety legislation specific to operators of commercial vehicles. Driver hours of service, cargo securement, dangerous goods transportation, weights and dimensions, and vehicle maintenance and road worthiness are the predominant focus of TEO inspection activities. Ontario’s Highway Traffic Act, its regulations, the Compulsory Automobile Insurance Act, and the Dangerous Goods Transportation Act are core pieces of legislation from which TEOs derive their enforcement authorities. TEOs conduct commercial vehicle inspections using a standardized procedure established by the Commercial Vehicle Safety Alliance (CVSA). 


Transportation Enforcement Officers inspect commercial vehicles, their loads, and driver’s qualifications and documentation. They collect evidence, issue provincial offence notices or summons to court for violations, and testify in court. 


Transportation Enforcement Officer deployment ranges from highway patrol and Truck Inspection Station (TIS) duties, audits of commercial vehicle operators, inspection and monitoring of bus and motor-coach operators, and the licensing and monitoring of Motor Vehicle Inspection Stations. Blitz-style joint force operations are periodically conducted in concert with provincial and municipal police.
