If you are thinking about becoming an HVAC technician in Ontario you are looking at a career that’s stable in demand and genuinely rewarding.. Before you can start installing furnaces or troubleshooting heat pumps you need to understand the licensing landscape for HVAC technicians in Ontario.
Here is the honest truth: there is no HVAC license for HVAC technicians in Ontario. The HVAC industry is broken down into specializations, including gas technician, oil burner technician, refrigeration mechanic and sheet metal worker, each with its own certification pathway for HVAC technicians.. Do not let that intimidate you because the process is straightforward once you know the steps for HVAC technicians.
Let us walk through everything you need to know about becoming an HVAC technician from education to certification, to finding work as an HVAC technician without the extra information you do not need to know about HVAC technicians.
First, Understand What “HVAC License” Actually Means in Ontario
In Ontario the rules for heating and air conditioning workers also known as HVAC are a bit different. You do not just get one license and that is it. Instead HVAC in Ontario has rules from the province and from the city. This means HVAC workers need to get a certificate from the province and also a license, from the city where they work.
Here’s how it breaks down:
1. Technical Certifications (TSSA) – These are your core credentials. The Technical Standards and Safety Authority (TSSA) governs gas and oil burner technicians. You need these to legally work on gas-fired or oil-fired equipment.
2. Skilled Trades Ontario – This is the provincial body that oversees apprenticeship programs and journeyperson certification for trades like refrigeration and sheet metal.
3. Municipal Trade Licences – Some cities, like Hamilton, require a separate trade licence to operate an HVAC business within city limits . This applies more to contractors than employees.
4. College Diplomas – While not mandatory, formal education is heavily recommended and often required by employers.
The path you take depends on which area of HVAC you want to work in residential heating, commercial refrigeration, or a bit of everything.
The Two Main Pathways to Certification
In Ontario, you generally have two routes to becoming a certified HVAC technician:
Pathway 1: College Diploma Program (Recommended)
This is the most common and structured route. Programs like Cambrian College’s Heating, Ventilation and Air Conditioning Technician (HVTN) program are TSSA-accredited and designed to prepare you for the certification exams .
What you get:
- A two-year college diploma in HVAC technology
- Eligibility to challenge TSSA Gas Technician and Oil Burner Technician exams
- Hands-on training in state-of-the-art labs
- The ability to work at entry-level positions after your first year
Admission requirements typically include:
- Ontario Secondary School Diploma (OSSD) or equivalent
- Any Grade 12 English (C) or (U)
- Any Grade 11 mathematics (C), (U), or (M)
The timeline: Two years of full-time study. After your first year, you can challenge the Gas Technician Level 3 and Oil Burner Technician Level 3 exams. After your second year, you move up to Gas Technician Level 2 and Oil Burner Technician Level 2 certifications .
Pathway 2: Apprenticeship Route
If college isn’t your path, you can pursue an apprenticeship through Skilled Trades Ontario. This involves:
- Finding an employer willing to sponsor you
- Completing on-the-job training (typically 4-5 years)
- Taking in-school technical training blocks
- Writing the certification exams
This route pays you while you learn, but it can take longer to become fully certified.
Key Certifications You’ll Need
Depending on your career goals, here are the main certifications to work toward:
| Certification | Issuing Body | What It Allows You To Do |
|---|---|---|
| Gas Technician Level 3 | TSSA | Entry-level gas work (appliance installation, venting) |
| Gas Technician Level 2 | TSSA | Full gas system installation and servicing |
| Oil Burner Technician Level 3 | TSSA | Entry-level oil burner work |
| Oil Burner Technician Level 2 | TSSA | Full oil burner installation and servicing |
| Refrigeration Mechanic | Skilled Trades Ontario | Work on refrigeration and air conditioning systems |
| Sheet Metal Worker | Skilled Trades Ontario | Fabricate and install ductwork |
A typical residential HVAC technician holds Gas Technician Level 2 and Oil Burner Technician Level 2 certifications.
Step-by-Step: Getting Certified in Ontario
Here’s a practical roadmap from start to finish:
Step 1: Meet the Education Prerequisites
To get started you need to get your high school diploma. The Education Prerequisites are very important. You have to make sure you have English and math credits on your high school diploma. If you are a student the Education Prerequisites can be different. The colleges may have admission pathways, for the Education Prerequisites.
Step 2: Enroll in an Accredited HVAC Program
Choose a TSSA-accredited college program (like Cambrian College, Mohawk, Humber, or George Brown). This saves you time because the curriculum is aligned with certification exams .
Step 3: Complete Year 1 (or Equivalent)
After your first year, you’ll be prepared to challenge the TSSA Gas Technician Level 3 and Oil Burner Technician Level 3 exams. Passing these allows you to work at entry-level positions .
Step 4: Complete Year 2
Finish your diploma and challenge the Gas Technician Level 2 and Oil Burner Technician Level 2 exams. This makes you fully certified to work as a heating systems technician .
Step 5: Consider Optional Certifications
If you want to work on refrigeration or sheet metal, you can pursue apprenticeships through Skilled Trades Ontario. This typically requires a supervised work period of about two years before certification .
Step 6: Get Municipal Licensing (If Applicable)
If you plan to start your own HVAC business, check with your local municipality. For example, Hamilton requires a trade licence (Master’s or Contractor’s) for HVAC businesses, and you’ll need proof of insurance, business registration, and photo ID to apply .
The Cost Factor
Let’s be upfront getting certified costs money. But it’s an investment that pays off.
- College tuition: $3,000–$6,000 per year for a two-year program
- TSSA exam fees: Varies by level (typically $200–$500 per exam)
- Textbooks and supplies: $500–$1,000
- Municipal licence: Varies by city (Hamilton charges application fees plus yearly renewal)
Many students qualify for OSAP or other financial aid to offset tuition costs.
What About Foreign-Trained Technicians?
If you earned your HVAC credentials outside of Canada, you can still work in Ontario but you’ll need to go through a foreign credential recognition process. Skilled Trades Ontario can assess your qualifications and determine what additional training or exams you need .
The process varies depending on your country of origin and your specific trade. It’s worth contacting Skilled Trades Ontario early to understand what you’ll need.
Working in HVAC – What It Looks Like Day-to-Day
Once you’re certified, your career options are wide open. HVAC technicians in Ontario work in residential, commercial, and industrial settings. Common tasks include:

Specialized Installations – The SpacePak Option
