Class A
- Class A lets you drive a motor vehicle towing vehicles whose total gross weight is more than 4,600 kg (10,000 lb), plus anything in classes D and G.
- Class A does not cover a bus carrying passengers, a motorcycle or a moped.

- Restricted Class A configuration: same weight rating, but the trailer has no air brakes.
- A road test taken in a vehicle that is not a full Class A configuration earns an AR (A restricted, condition R) licence, which does not allow driving a full Class A vehicle.
Minimum requirements

- You must already hold a valid Ontario Class G or higher licence (not G1, G2, M, M1 or M2).
- You must pass a knowledge test on operating large trucks and tractor-trailers, meet the vision standard and provide a satisfactory medical certificate, both on application and periodically after that.
- A learner practising on a tractor-trailer must hold Class G or higher and be accompanied by a driver holding a valid Class A licence.

- The knowledge test is written from the Official MTO Truck Handbook.
Introduction (mandatory entry-level training)
- Since July 1, 2017, new Class A applicants must complete mandatory entry-level training (MELT) before attempting the Class A road test.
- The MELT course takes roughly four to six weeks with a ministry-approved provider.
- Drivers who already held a Class A licence before MELT did not have to take the training.
Class A transmission restriction
- Since July 1, 2022, a Class A or AR road test taken in a vehicle without a manual transmission of at least eight forward gears with a high-low range adds a restriction to the licence.
- With that restriction you may drive only automatic, semi-automatic or automated-manual Class A/AR vehicles in Ontario; it does not affect lower classes such as D or G.
- A restricted Class A (condition R) holder cannot pull a trailer with air brakes, drive a full-size tractor-trailer, pull double trailers or train another driver on a full Class A vehicle.
- A full Class AZ licence is the only licence that covers full air brake systems on both tractor and trailer and allows double trailers.
Who may assess the road test
- The road test is held at a DriveTest centre, or by an employer or college the ministry authorizes as a Recognized Authority, which issues a certificate of driving competence.
- A truck licence from another Canadian province is exchanged for the same Ontario class.
