If you’re wondering how to get your AZ license in Ontario, you’re not alone — it’s one of the most searched questions by people ready to launch a career in trucking. The AZ license is the highest class of commercial driver’s licence in the province, allowing you to operate any tractor-trailer or combination vehicle, and earning it opens the door to one of the most in-demand careers in Canada right now.
This guide walks you through every step — from eligibility requirements to the road test — so you know exactly what to expect before you sign up for training.
What Is an AZ License in Ontario?
An AZ license (also called an Ontario Class A licence) is the commercial driver’s licence that allows you to drive any combination vehicle — tractor-trailers, semi-trucks, and any truck towing a trailer — on Ontario roads and across Canada.
It’s the top-tier commercial licence in the province. With an AZ licence, you can legally operate vehicles that would otherwise require a Class B, C, D, E, F, or G licence. In other words, it covers everything below it.
This is different from a DZ licence, which only covers straight trucks without a trailer. If your goal is to drive tractor-trailers for long-haul or local freight, the AZ is the licence you need.
The trucking industry in Ontario is facing a serious driver shortage, which means qualified AZ truck driver licence Ontario holders are in high demand and can expect strong wages and job security right out of training.
AZ License Ontario Requirements: Do You Qualify?
Before you can begin training, you need to meet a few baseline requirements set by the Ontario Ministry of Transportation:
- Age: You must be at least 18 years old
- Valid G licence: You must hold a full Ontario Class G driver’s licence (not G2)
- Medical exam: You must pass a commercial driver’s medical examination — your doctor completes a standard MTO medical report confirming you meet the physical requirements
- Vision: You must meet minimum commercial vision standards
- Driving record: While a perfectly clean record isn’t mandatory, serious suspensions or Criminal Code convictions may affect eligibility
If you’re comparing the AZ to other commercial licence classes — like DZ, BZ, or restricted A — our guide on what licence you need to become a truck driver in Ontario breaks down exactly which class fits which career path.
Step 1: Pass the AZ Written Knowledge Test
The first formal step is passing the AZ knowledge test at any Ontario DriveTest centre. The test covers:
- Air brakes and air brake systems
- Combination vehicle operation
- Hours of service rules
- Safe driving practices for large commercial vehicles
The fee is approximately $16. You’re allowed — and encouraged — to study using the official Ontario truck driver’s handbook, which you can download free from the Ontario government website. Most students take one to two weeks to prepare if they study consistently.
Once you pass, you receive your AZ learner’s permit, which allows you to practise driving a tractor-trailer under the direct supervision of a licenced AZ driver.
Step 2: Complete Your MELT Training Program
This is the most critical step — and since 2017, it has been mandatory for every new AZ licence applicant in Ontario without exception.
MELT stands for Mandatory Entry-Level Training. It is a provincially regulated training curriculum ensuring that every new commercial driver in Ontario meets a consistent safety standard before being licensed. You cannot book the AZ road test without a MELT completion certificate.
The Ontario MELT program requires a minimum of 103.5 hours of combined training:
- In-class instruction — truck systems, regulations, hours of service, load securement, and pre-trip inspections
- Yard training — basic vehicle control, backing manoeuvres, coupling and uncoupling a trailer
- In-cab road training — real on-road time behind the wheel of a tractor-trailer
At Great Lakes Truck Driving School, our AZ Tractor Trailer MELT Program is fully approved by the province and covers every required MELT component. The school is registered as a Career College under the Ontario Career Colleges Act, 2005 — meaning the program meets government-mandated quality standards. Our instructors bring over 30 years of combined experience in the trucking industry, and all tuition fees are tax deductible.
Step 3: AZ License Ontario Cost — What to Budget
AZ licence cost Ontario is one of the top questions prospective students ask. Here’s a realistic breakdown of what to expect:
| Item | Approximate Cost |
|---|---|
| AZ knowledge test (DriveTest) | ~$16 |
| Commercial medical exam | $75–$150 |
| MELT training program | $5,000–$10,000 |
| AZ road test (DriveTest) | ~$52 |
| Licence upgrade fee (ServiceOntario) | ~$90 |
| Total estimated range | $5,200–$10,300 |
The MELT training program is the largest cost. Keep in mind that tuition is tax deductible as a vocational training expense, which meaningfully reduces the real out-of-pocket cost. Some carriers also offer sponsorship arrangements — they cover your training in exchange for a commitment to drive for them for a set period after hiring.
Step 4: Pass Your AZ Road Test
Once MELT is complete, you book your AZ road test at a DriveTest centre. This is a practical exam conducted in an actual tractor-trailer. The examiner will assess:
- Pre-trip inspection — this is graded thoroughly, not casually
- Basic vehicle control — backing, turning, coupling
- On-road driving — following distance, speed management, lane discipline, mirror use
- Air brake operation
Pre-trip inspection is the section most students underestimate. It is scored point-by-point and mistakes add up quickly. Our post on useful tips for pre-trip inspection covers exactly what examiners look for and how to approach it systematically — read it before your test day.
96% of our students pass the road test on their first attempt. Consistent practice during your MELT program is what makes the difference.
What Happens After You Get Your AZ Licence?
Once you pass the road test, you upgrade your licence at a ServiceOntario location and officially become a licenced Class AZ driver in Ontario.
From there, most graduates move directly into employment. Canada’s trucking industry is experiencing a well-documented shortage of commercial drivers, with tens of thousands of positions unfilled. Long-haul, regional, and local freight carriers are actively hiring AZ graduates, often immediately after licensing.
Our resources page has additional study materials to help you prepare for both the knowledge test and road test — including practice questions and inspection guides.
Frequently Asked Questions
How long does it take to get an AZ licence in Ontario? Most students complete the full process in 4 to 8 weeks. The MELT program itself takes 3 to 5 weeks depending on whether you’re enrolled full-time or part-time. Add in test booking wait times and you’re typically looking at under two months from start to licensed.
Can I get my AZ licence without going to truck driving school? No. Since 2017, Ontario requires all new AZ applicants to complete a provincially approved MELT program before sitting the road test. There is no way to bypass this requirement — it applies to everyone getting their AZ for the first time.
How much does AZ licence training cost in Ontario? MELT training typically runs between $5,000 and $10,000 depending on the school and program format. Total costs including tests, medical, and licence fees generally land in the $5,200–$10,300 range. Tuition is tax deductible as a vocational program expense.
What is the difference between an AZ and DZ licence in Ontario? A DZ licence covers straight trucks — vehicles without a trailer. An AZ licence covers combination vehicles, including tractor-trailers. AZ is the higher qualification, opens more job categories, and typically comes with higher pay. If tractor-trailer driving is your goal, AZ is the licence to get.
