April 24, 2025

If you’re considering a career in commercial driving in Ontario, one of the first decisions you’ll face is choosing between an AZ and DZ license. While both open doors to rewarding opportunities in the transportation industry, they serve different purposes, vehicle types, and career paths.


In this blog, we’ll break down the key differences between AZ and DZ licenses, help you decide which is right for you, and explain how Trukademy can guide you through the process.

What is an AZ License?

An AZ license is the highest class of commercial license in Ontario. It allows drivers to operate any truck/tractor-trailer combination, including:

  • Garbage trucks


Key Features of a DZ License:


  • Operate vehicles over 11,000 kg with no towed trailer over 4,600 kg

Which License Should You Choose?

Choosing between an AZ and DZ license depends on your lifestyle goals, career aspirations, and willingness to travel.


Choose AZ if you:

  • Want to earn a higher income
  • Are open to cross-border or long-haul travel
  • Are interested in advanced vehicles like tractor-trailers
  • Don’t mind being on the road for days at a time


Choose DZ if you:

  • Are looking to enter the workforce quickly
  • Want to work with construction or municipal fleets


Training Requirements

Both licenses require you to pass a written knowledge test, vision test, and road test. However, AZ license holders must also complete the (Mandatory Entry-Level Training) MELT program, which includes both in-class and in-vehicle instruction.
