Ontario ordered some A/Z drivers to retest after an audit of their test provider

In July 2025, Ontario's Ministry of Transportation (MTO) sent letters ordering some Class A/Z truck drivers to retake their knowledge and road tests after an audit raised concerns about the organization that had tested them.

The letters, obtained by trucknews.com, said the ministry could not verify that the drivers' tests had been conducted to Ontario standards because of irregularities found during an audit of their test provider. An MTO official said an audit of a Driver Certification Program organization found tests may not have been run according to ministry requirements.

What drivers had to do

• Pass a vision and knowledge test within 60 days of the date of the letter.
• Pass a road test within 120 days, at a DriveTest centre.
• Pay for the retests and supply their own Class A truck and trailer combination with full air brakes.

The MTO cited section 32(5) of the Highway Traffic Act and section 15 of Ontario Regulation 340/94 as its authority.

Consequences

Drivers who failed a test, or missed either deadline, would have their A/Z licence downgraded to the next highest class they were qualified to hold. They could upgrade again later by completing all required testing.

Trucknews.com said it knew of at least two drivers who had received the letter, including one licensed about a year earlier who had been running long-haul trips to the U.S. The Ontario Trucking Association republished the report on its website.
