To access a full PDF version of the CVOR Public Guideline or to view individual sections or Appendices, please visit CVOR Public Guideline Resources.The Commercial Vehicle Operator’s Registration (CVOR) system and the Carrier Safety Rating (CSR) program were developed by the Ministry of Transportation as part of Ontario’s ongoing commitment to road safety. These programs promote the safe operation of trucks and buses on Ontario’s roadways.This guideline is for operators of commercial motor vehicles. This includes trucks that have a registered gross weight of over 4,500 kilograms, and buses that can carry ten or more passengers. Owners/operators of these vehicles must apply for, obtain and renew a Commercial Vehicle Operator’s Registration (CVOR) certificate.

Each carrier is responsible for monitoring its CVOR record and the performance information it provides, including violation rates, thresholds, audit scores and resulting Safety Rating. The carrier should identify and address problem areas in order to improve its commercial motor vehicle safety performance.

The CVOR system is part of the Carrier Safety Rating (CSR) program. The Ministry of Transportation monitors carriers and assigns each a Safety Rating based on several factors: collisions, inspections, and convictions, as well as the results of facility audits.

To operate in Ontario, carriers must follow the laws and regulations that apply to the operation of trucks and buses, which includes, but is not limited to:

  • The Highway Traffic Act
  • Transportation of Dangerous Goods Act
  • Public Vehicles Act
  • Motor Vehicle Transport Act
  • Compulsory Automobile Insurance Act
  • Fuel Tax Act
