How to Get Your DZ License in Ontario: A Complete Step-by-Step Guide (2026)
If you’re looking to get your DZ license in Ontario, you’re pursuing one of the most practical and in-demand commercial driving credentials in the province. The DZ licence — also called a Class D licence — qualifies you to operate straight trucks over 11,000 kg, making it the entry point for dump truck drivers, large delivery drivers, tow truck operators, and dozens of other commercial driving roles across Ontario.
This guide covers exactly what the process looks like in 2026, what it costs, how long it takes, and what you can earn once you have it.
What Is a DZ Licence in Ontario?
A DZ licence is the Ontario Class D commercial driver’s licence with a “Z” air brake endorsement attached. The “D” covers the vehicle class — any straight truck or combination vehicle exceeding 11,000 kg where the towed unit does not exceed 4,600 kg. The “Z” endorsement authorizes you to operate any vehicle equipped with air brakes.
In practice, a DZ qualifies you to drive:
- Dump trucks
- Large flatbed delivery trucks
- Moving trucks
- Tow trucks
- Straight body trucks and box trucks over 11,000 kg
- Certain construction and utility vehicles
A DZ does not authorize combination vehicles where the trailer exceeds 4,600 kg — that requires an AZ (Class A) licence. If your goal is tractor-trailer driving, see our guide on how to get your AZ license in Ontario. If you’re unsure which licence class fits your specific career goal, our post on what licence you need to become a truck driver in Ontario breaks down every commercial class in plain language.
DZ Licence Requirements in Ontario
Before you can begin the DZ licensing process, you need to meet these baseline requirements set by the Ministry of Transportation Ontario (MTO):
- Age: You must be at least 18 years old
- Valid Class G licence: A full Class G is required — a G2 is not sufficient
- Commercial medical examination: You must pass a medical exam completed by a licensed physician using the MTO medical report form. This confirms you meet the physical and vision standards for commercial driving
- Clean enough record: While a perfect driving record isn’t mandatory, serious suspensions or Criminal Code convictions may affect eligibility
The type of truck licence you need in Ontario depends on the weight of the truck, the towed vehicle, and their combined weight. All licences require a knowledge test and a road test, and you may also need to take a government-approved training course.

Step 1 — Pass the DZ Knowledge Test
The first formal step is passing the DZ knowledge test at a DriveTest centre. The test covers:
- Class D vehicle operation and regulations
- Air brake systems (required for the Z endorsement)
- Hours of service rules
- Load security and safe driving practices for large straight trucks
Study material: The official Ontario MTO Truck Handbook is the primary study resource for both Class A and Class D applicants. It’s available free to download from the Ontario government website and covers everything the knowledge test assesses.
Fee: Approximately $16 at any Ontario DriveTest centre. You can book online or by phone.
Result: Pass the test and you receive your DZ learner’s licence (also called a beginner’s licence). This permits you to drive a Class D vehicle on Ontario roads while accompanied by a licensed DZ or AZ driver in the cab.
Step 2 — Complete Commercial Driver Training
This step is not provincially mandated for Class D the way MELT is for Class A — but it is strongly recommended and it directly determines your road test pass rate.
A qualified commercial driving instructor teaches you:
- Vehicle controls and pre-trip inspection on a straight truck
- Backing, turning, and maneuvering large vehicles in confined spaces
- Air brake operation and testing procedures
- Shifting technique on manual transmissions where applicable
- Defensive driving practices specific to large commercial vehicles
The pre-trip inspection component deserves specific attention. The DZ road test grades the pre-trip inspection systematically — it’s one of the most common reasons candidates fail. Our post on useful tips for pre-trip inspection covers the exact methodology examiners use so you can practise it to standard before your test.
Professional training also gives you supervised road hours on a vehicle you won’t have access to otherwise. Attempting the road test without proper vehicle time behind you is the fastest way to fail and delay your licensing by weeks.
Step 3 — Pass the DZ Road Test
Once you’re trained and confident, you book the DZ road test at a DriveTest centre. The practical exam is conducted in a Class D vehicle and assesses:
Pre-trip inspection — systematically checking the vehicle before driving. This section is scored point-by-point. Missing components accumulates errors quickly. Treat pre-trip as a core skill, not a formality.
Air brake test — demonstrating correct air brake operation, including pressure buildup, governor cut-in/cut-out, and leak-down rates.
Basic vehicle control — straight-line backing, turns, and alley docking manoeuvres in the yard area.
On-road driving — assessed for following distance, mirror use, lane discipline, speed management, smooth braking, and intersection handling. The examiner is looking for consistent, professional-level operation — not perfection on every individual action.
DZ road test fee: Approximately $52 at a DriveTest centre.
Tip from experienced instructors: Mirror use is the single most common deduction on commercial road tests. Establish the habit of scanning your mirrors every 5–8 seconds and making it visibly deliberate — examiners specifically watch for mirror scanning frequency.
Step 4 — Upgrade Your Licence at ServiceOntario
Once you pass the road test, you upgrade your Class G to a full DZ at any ServiceOntario location.
Licence upgrade fee: Approximately $90.
Bring your road test certificate, your current driver’s licence, and payment. The upgrade is processed the same day.
How Much Does Getting a DZ Licence Cost in Ontario?
Here’s the realistic total cost breakdown for getting your DZ licence in 2026:
| Item | Approximate Cost |
|---|---|
| Commercial medical examination | $75 – $150 |
| DZ knowledge test (DriveTest) | ~$16 |
| DZ road test (DriveTest) | ~$52 |
| Licence upgrade (ServiceOntario) | ~$90 |
| Commercial driver training | $1,500 – $4,000 |
| Total estimated range | $1,700 – $4,300 |
The training program is by far the largest cost component. The right way to evaluate it is against what a DZ licence earns you — which we cover in the next section. At $60,000+ per year for a starting DZ driver in Ontario, training pays for itself within the first two months of employment.
Note that DZ training costs are eligible as a vocational education tax credit, reducing the real after-tax cost of the program.
DZ vs AZ Licence — Which One Is Right for You?
This is the question most candidates reach when they start researching commercial driving in Ontario.
DZ covers straight trucks — vehicles where the cargo box, flatbed, or body is built onto the truck frame itself. No separate trailer unit.
AZ covers combination vehicles — a tractor pulling a separate trailer. Tractor-trailers, semi-trucks, B-trains. The AZ also covers everything the DZ covers, making it the higher-value licence.
Which should you get?
Choose DZ if your employment goal is dump truck driving, large delivery, construction vehicles, tow truck operation, or roles that specifically require straight trucks.
Choose AZ if your goal is long-haul freight, intermodal transport, or any tractor-trailer operation. The AZ opens more job categories and typically pays $10,000–$20,000 more per year than DZ-only positions.
The DZ is also a legitimate stepping stone — some drivers get their DZ first for faster entry into commercial driving, then upgrade to AZ within a year as they gain road experience.
Truck Driver Salary in Ontario — What DZ Drivers Earn
Understanding earning potential is part of making an informed decision about the training investment.
DZ drivers in Ontario typically earn:
| Role | Annual Salary Range |
|---|---|
| Entry-level DZ driver | $55,000 – $65,000 |
| Experienced DZ driver (3+ years) | $65,000 – $80,000 |
| Specialized DZ (tanker, crane truck) | $75,000 – $95,000 |
| Owner-operator DZ | $80,000 – $120,000+ |
The Ontario trucking sector continues to face a significant driver shortage, meaning qualified DZ drivers are in demand across construction, logistics, waste management, and utility sectors across Windsor, the GTA, and provincial infrastructure projects.
Wages have risen substantially since 2022 and continue to reflect competitive hiring conditions. Many employers also offer health benefits, pension contributions, and sign-on bonuses for qualified DZ candidates.
Frequently Asked Questions
How long does it take to get a DZ licence in Ontario?
The full process — medical, knowledge test, training, and road test — takes most candidates 4 to 8 weeks. The knowledge test and medical can be completed in the first week. Training typically runs 2 to 4 weeks depending on your schedule. Road test booking availability at DriveTest varies by location but is typically 1 to 3 weeks.
Do I need mandatory MELT training for my DZ licence?
No. MELT (Mandatory Entry-Level Training) applies specifically to Class A (AZ) licence applicants. Class D (DZ) does not require MELT. You need to pass a knowledge test and road test, and professional training is strongly recommended to maximize your pass rate — but the mandatory training hours requirement does not apply.
Can I get my DZ licence if I already have my AZ?
If you already hold a valid AZ licence, you are already authorized to operate all Class D vehicles — the AZ covers everything the DZ covers and more. You do not need to obtain a separate DZ.
What vehicles can I drive with a DZ in Ontario?
Any straight truck or combination vehicle exceeding 11,000 kg where the towed unit does not exceed 4,600 kg. This includes dump trucks, large delivery trucks, moving trucks, and tow trucks. It does not include tractor-trailers — those require a Class A (AZ) licence.
How much does DZ licence training cost in Ontario?
Training programs vary from approximately $1,500 to $4,000 depending on the school, program length, and location. Add roughly $250–$300 for tests, medical, and licence fees. Most programs can be completed in under a month. Tuition is eligible as a vocational training tax credit.
