Commercial Vehicle Operators’ Safety Manual


Reporting CVOR Changes or Errors (Current CVOR Registrants)


Under Subsection 18(1) of the Highway Traffic Act (HTA), changes to corporate officers (officers, directors or partners), operator name or address must be reported to the ministry within 15 days. Changes to shareholders should not be reported.

The HTA requires that changes to fleet size and kilometres travelled must also be reported to the Deputy Registrar. A change that increases or decreases an operator's fleet size by more than 20 percent must be reported within 15 days after the change, or within 15 days of receiving a request from the Deputy Registrar for this information. Changes to kilometres travelled must also be reported to the Deputy Registrar upon receiving a request for this information. Failure to do so could result in charges being laid against the operator and is a condition of retaining a CVOR certificate.

A new certificate will only be issued for changes to the operator name, or if a replacement is required due to loss, damage and so on. All name changes require proper and legal supporting documentation.


Corporate Officers/Directors

If there is a change of corporate officers and/or directors, the operator must contact MTO Carrier Sanctions and Investigation Office to have a CVOR update application sent to them.


Fleet Size/Kilometres Travelled

If there is a change in fleet size or kilometres travelled, the operator must contact MTO Carrier Sanctions and Investigation Office to have a CVOR update application sent to them. Note: Changes to fleet size and rate of travel are not automatically captured through the province's vehicle registration system (for example, licence-plate renewal, permit purchase or deletion).


Name/Address

Name or address changes for an individual can be made at a driver and vehicle licence- issuing office through the vehicle registration system.

Address changes for a corporation can be made at a driver and vehicle licence-issuing office.

Name changes for a corporation must be made through the licensing administration and support office by mail, at 2680 Keele Street, Downsview, Ontario M3M 3E6, or by telephone at (416) 235-2999.

Note: A new CVOR certificate will be issued for name changes, but not for address changes.


The Operator's Fleet Size

The vehicles that must be reported as part of an operator's fleet size are all trucks (including leased, rented and owned) having a gross weight or registered gross weight of more than 4,500 kilograms and all buses. (A bus is a motor vehicle designed to carry 10 or more passengers, not including the driver.) Trailers and converter dollies are not counted as part of the fleet size.

These include:

  • All the trucks and buses in an operator's fleet that operate in Ontario and are plated in Ontario, the U.S. or Mexico

These do not include:

  • Any trucks or buses in an operator's fleet that are plated in other Canadian jurisdictions
  • Any trucks or buses in an operator's fleet that NEVER travel in Ontario
  • Any trailers or trailer converter dollies in an operator's fleet

Fleet/kilometric data

The Highway Traffic Act requires operators to report fleet size and travel information to the ministry within 15 days after a change in the fleet size of 20 percent greater or less than last reported, as well as upon request. If the fleet size or rate of travel fluctuates throughout the year, the average rate of travel in Canada for the fleet operating in or through Ontario should be reported.

Operators must maintain travel records (over a period of up to 24 months) of the kilometres travelled by the trucks and buses in its fleet. These records must be kept separate (for example, one record of kilometric travel for trucks and a separate record for buses).

Operators must report any significant changes in:

  • Total kilometres driven in Ontario
  • Total kilometres driven in all other Canadian jurisdictions
  • Total kilometres driven outside of Canada

Note: For more information on determining fleet size and rate of travel please contact MTO Carrier Sanctions and Investigation Office.
