Introduction

In case you have had an active DZ license already, and are considering moving your career to the next stage and becoming a truck driver, you are not the only one. Most of the professional drivers in Ontario want to enhance their license to gain more job opportunities, their earning power and flexibility on the road. This tutorial will take you through the process of changing your DZ license to AZ license in a smooth way including eligibility, training, expenses, and hints to passing a road test.

Understanding the Difference Between DZ and AZ Licenses

It is important to learn what the difference between DZ license and AZ license entails before considering the move.

• DZ License gives you access to drive straight trucks, fire trucks, cement trucks, dump trucks and so on.

• AZ License also covers all those vehicles which are covered under the DZ license along with tractor-trailers, long combination vehicles (LCVs) and other heavy commercial vehicles.

With the upgrade to AZ license new career opportunities become available where long-haul and freight transport is concerned.

Why Switch from DZ to AZ License?

Here are some strong reasons drivers choose to upgrade:

• Higher salary potential

• Greater job variety

• Increased demand across provinces

• Ability to drive across Canada and into the U.S.

• Potential for owner-operator roles

Switching isn’t just about driving bigger trucks—it’s about growing your career.

Step 1: Check Eligibility Requirements

To begin the process to switch from DZ to AZ license, you must meet the following:

• Be at least 18 years old

• Hold a valid Ontario Class G or higher license

• Pass a medical examination

• Have a clean driving record

Meeting these basic requirements ensures you’re ready to proceed with training and testing.

Step 2: Pass the Medical Exam

A medical exam is mandatory for any commercial license in Ontario.

• Must be completed by a licensed physician

• Tests your vision, hearing, cardiovascular health, and more

• Submit the medical report to the Ministry of Transportation (MTO)

Without a valid medical, your application for an AZ license won’t be processed.

Step 3: Enroll in an Approved MELT Program

The Mandatory Entry-Level Training (MELT) program is a government-required course before you can take the AZ road test.

• Includes a minimum of 103.5 hours of instruction

• Covers vehicle inspection, road training, safety regulations, and more

• Must be taken from an MTO-approved training school

If you’re switching from DZ to AZ, much of your prior driving experience will help, but formal MELT training is still necessary.

Step 4: Study for the Written Knowledge Test

Before you can take your road test, you must pass the AZ written knowledge test:

• Covers traffic laws, truck-specific regulations, and safety procedures

• Study the Official MTO Truck Handbook

• Practice with online sample tests

Passing this test earns you your AZ learner’s permit.

Step 5: Practice Your Skills with a Training School

Once you have your learner’s permit, practical training begins.

• Focus on skills like backing up, lane changes, turns, and inspections

• Simulate real-world conditions like city and highway driving

• Learn coupling and uncoupling of trailers

Choose a school that specializes in helping drivers switch from DZ to AZ license with tailored programs.

Step 6: Take and Pass the AZ Road Test

The final hurdle is passing the road test administered by Drive Test Ontario.

• Test includes a pre-trip inspection, coupling/unloading test, and road test

• Be punctual and prepared with all documents

• Remain calm and confident; training pays off

Passing this test officially upgrades your license to AZ.

Step 7: Apply for Job Opportunities

Now that you’ve made the switch, it’s time to hit the job market!

• Update your resume with your AZ license

• Apply to local and long-haul carriers

• Use job platforms like Indeed, Trucking HR Canada, and Workopolis

Many companies look favourably on drivers who recently switched from DZ to AZ license and completed MELT training.

Common Mistakes to Avoid

• Skipping the medical test early in the process
