How to Get Your Commercial DZ Driver’s License in Ontario

driving a car

A DZ driver’s license is a special type of license issued by the province of Ontario, Canada, that allows individuals to operate certain types of commercial vehicles. Drivers with a DZ license are authorized to drive trucks and tractor-trailers, as well as other vehicles with air brakes.

In order to obtain a DZ license, an individual must pass a knowledge test and a road test. The knowledge test covers topics such as traffic laws and regulations, vehicle operation and safety, and basic vehicle maintenance. The road test requires the individual to demonstrate their ability to safely and properly operate the vehicle.

If you are looking to get your DZ driver’s license in Ontario, you’ve come to the right place! This guide will provide you with all the information you need to know in order to obtain your DZ license, from the application process to the testing requirements. 


The first step is to ensure you are eligible to obtain a DZ license. To do this, you must meet all the following criteria: 

  • Be at least 18 years old 
  • Have a valid Ontario driver’s license 
  • Have a valid Ontario vehicle registration 
  • Pass a medical exam 
  • Pass a skills test and road test 
  • Pass a vision test 
  • Have a valid commercial vehicle safety inspection certificate 

Once you have met all the eligibility requirements, you can begin the application process. You will need to complete an Application for a Driver’s Licence (Form G1) and submit it to your local testing centre. You should also bring two pieces of ID, such as a birth certificate or passport.


Once your application is approved, you will need to complete the knowledge test. This is a written exam that covers topics such as rules of the road, traffic signs, and safe driving practices. The test is available in multiple languages and you can take it at the testing centre. 

Once you pass the knowledge test, you can begin the skills test and road test. This will involve driving a commercial vehicle in different traffic and road conditions, including highways and city streets. You must pass both tests in order to receive your DZ license.

Final Steps

Once you have passed the skills test and road test, you will need to have a valid commercial vehicle safety inspection certificate. This can be obtained from any licensed inspection facility.

Finally, you will need to submit your application and all supporting documents to Service Ontario. They will review your application and issue you a DZ license if you meet all the requirements.
