HVAC Technician Resume Guide (Canada): Red Seal, Tickets, and the Jobs Worth Chasing
An HVAC tech's resume is one of the more crowded categories on Canadian job boards — and one of the easiest to read past if it doesn't show the right things. Service techs, install techs, and commissioning techs all carry the title. What separates them is the trade certification, the federal ODP card, the gas fitter class, and whether they've actually worked chilled-water plants, big rooftop units, or data center cooling instead of just residential furnaces.
This guide is for journeyperson refrigeration and air conditioning mechanics, residential AC techs, and senior apprentices building a resume aimed at the Canadian market. We'll cover the Red Seal trail, the provincial code variations, the tickets that matter, and how to frame the work that actually pays.
Free for workers. Upload your existing resume to TradeCraft and we'll build a recruiter-ready profile in five minutes — Red Seal, ODP, gas tickets, employers all parsed.
What recruiters look for on an HVAC technician resume in Canada
Service managers and ICI superintendents read HVAC resumes in roughly this order:
01
Trade certification
Red Seal Refrigeration and Air Conditioning Mechanic, or provincial journeyperson. Ontario 313A vs 313D matters; spell it out.
02
ODP card
the federal Environmental Code of Practice for refrigerants. Mandatory for anyone handling refrigerant in Canada.
03
Gas fitter class
G3, G2, or G1 in Ontario; A or B in other provinces. Most commercial HVAC work needs G2 minimum.
04
System experience
chilled water, DX rooftop, VRF/VRV, CRAC/CRAH, hydronic, BAS controls.
05
The ticket stack
CSTS-2020, Fall Protection, Confined Space, WHMIS, First Aid.
If you're chasing data center cooling roles, the resume needs to scream chilled-water plant, CRAC/CRAH commissioning, BAS integration. If you're chasing residential service, it needs to show furnace and AC installation, ductwork, and customer-facing service. Different jobs, different framings — but the trade core is the same.
Red Seal context
Red Seal context: 313A, 313D, and provincial variation
The Red Seal trade is Refrigeration and Air Conditioning Mechanic. Provinces structure it as follows — and crucially, certification is compulsory in seven of ten provinces for this trade:
Ontario
code 313A for Refrigeration and Air Conditioning Systems Mechanic (compulsory) and 313D for Residential Air Conditioning Systems Mechanic (compulsory). Both regulated under Skilled Trades Ontario.
Alberta
journeyperson Refrigeration and Air Conditioning Mechanic through AIT. Compulsory. Four-year apprenticeship.
British Columbia
Refrigeration and Air Conditioning Mechanic through SkilledTradesBC. Regulated trade.
Saskatchewan, Manitoba, Quebec, Nova Scotia, New Brunswick
also compulsory certification for the RAC mechanic trade.
Newfoundland and the territories
voluntary certification.
The two Ontario codes matter on a resume. 313A covers residential, commercial, and industrial refrigeration and air conditioning systems plus combined heating-cooling work — the broadest scope. 313D covers residential air conditioning systems only — narrower scope, but easier and faster to achieve. A 313D holder cannot legally work on commercial refrigeration or industrial systems.
If you hold 313A, lead with it. It's the more valuable ticket. If you hold 313D and you're moving into commercial work, you'll typically need to retrain and challenge the 313A exam.
The Red Seal endorsement comes after passing the Interprovincial Standards Examination and makes you portable across the country. "Journeyperson" is the standard provincial term, but "journeyman" still appears in postings.
Tickets
The tickets that get an HVAC tech on site
Beyond your trade ticket, the certifications and cards that recruiters look for:
01
Environmental Awareness Course for Refrigerant Handling (ODP card)
Ozone Depletion Prevention. Federally required for anyone purchasing, handling, or working with refrigerants in Canada. Issued through HRAI, RSES, or provincial equivalents.
02
Gas fitter class
G3, G2, G1 in Ontario through TSSA. A or B in BC, Alberta, Saskatchewan, and Manitoba. Most ICI HVAC techs hold at least G2 (or B in other provinces).
03
TSSA Certificate of Authorization
if you'll be operating as or for a refrigeration contractor in Ontario.
04
CSTS-2020
for any construction or ICI site.
05
Working at Heights / Fall Protection
essential for rooftop unit work. Ontario MOL-approved Working at Heights inside Ontario.
06
Confined Space Entry

07
WHMIS 2015, Standard First Aid, CPR-C
table stakes.
08
Hot Work / Fire Watch
common on occupied buildings.
09
Aerial Work Platform / Boom & Scissor
useful for rooftop and large-scale install work.
Specialty tickets worth listing if you have them: manufacturer training (Trane TRACER, Carrier i-Vu, Daikin VRV/VRF certified, Mitsubishi VRF, Liebert/Vertiv CRAC, Schneider StruxureWare BAS), brazing certifications (CWB W47.1 for refrigerant piping where applicable), and electrical add-ons for techs cross-trained on motor controls.
Where the work is
Hot sectors hiring Canadian HVAC technicians right now
01
Data center cooling and mission-critical
Data center build-out across the GTA, Greater Montreal, and the Calgary corridor has pulled HVAC techs hard. The work is chilled-water plants (centrifugal chillers, cooling towers, pumps), CRAC and CRAH unit install and commissioning, in-row cooling, hot-aisle/cold-aisle containment, leak detection, and BAS controls integration. If you've worked a Microsoft, Google, AWS, Equinix, or major colo facility, lead with it. Recruiters search for "chiller," "CRAC," "CRAH," "Liebert," "Trane," "redundancy testing," and "commissioning."
02
ICI commercial — office, healthcare, education
The bread-and-butter of HVAC work in Canada. Mechanical contractors in every major city run continuous work on commercial towers, hospital retrofits, school board capital projects, and transit infrastructure. The work is rooftop units (Carrier, York, Lennox, Trane), VAV systems, VRF/VRV install (Daikin, Mitsubishi), DDC/BAS controls, hydronic and chilled-water mechanical rooms, ductwork integration. Name the contractor (Modern Niagara, Black & McDonald, Plan Group, Smith + Andersen consulting) and the building.
03
Residential service and replacement
BC and Alberta still have a strong residential boom. Toronto's mid-rise pipeline keeps service trucks busy. Residential service techs working furnace and AC change-outs, ducted heat pump installs (cold-climate heat pumps under federal rebate programs), ductwork, and IAQ work are constantly in demand. Customer-facing skills matter here — if you've held a high CSAT or referral rate, mention it.
04
Oil sands and industrial refrigeration
Process refrigeration on oil sands, food and beverage, ice rinks, and cold-storage facilities. Ammonia refrigeration (NH₃) and CO₂ transcritical systems are specialty work — if you've got it, it's a premium.
05
Cold-climate heat pump and electrification
Federal and provincial rebate programs (Canada Greener Homes, BC's CleanBC, Ontario residential incentives) are driving heat-pump installation volume. Cold-climate ducted and ductless heat-pump work has become a steady specialty for residential techs.

Notice what's missing: "responsible for," "duties included," "team player." Specific equipment, specific manufacturers, specific buildings, specific outcomes.
Build once. Find it anywhere.
Build it once, use it everywhere
HVAC work is mobile. Service techs swap territories. Commissioning techs follow projects. Install crews move between contractors. The resume that gets a callback is the one that's already in front of recruiters when the job opens — not the one you'll dust off next month.
That's how TradeCraft works. Upload your existing resume. We pull out the Red Seal, the ODP, the gas class, the manufacturer training, and the contractors you've worked for. You review every detail, decide what's visible to recruiters and what stays private, and the system watches new postings against your trade and tickets.
The exported resume is yours. Use it on TradeCraft. Use it everywhere else.
Get on data center and ICI shortlists. Build your profile in five minutes.
Yes. The Red Seal trade is Refrigeration and Air Conditioning Mechanic. Apprenticeship and certification is compulsory in Ontario, Alberta, BC, Saskatchewan, Manitoba, Quebec, Nova Scotia, and New Brunswick. The Red Seal endorsement is earned by passing the Interprovincial Standards Examination and makes you portable across the country.
What's the difference between Ontario 313A and 313D?
313A is the Refrigeration and Air Conditioning Systems Mechanic — covers residential, commercial, and industrial refrigeration and air conditioning systems plus combined heating and cooling. 313D is the Residential Air Conditioning Systems Mechanic — covers residential AC systems only, with a much narrower scope. Both are compulsory in Ontario. A 313D holder cannot legally work on commercial refrigeration; if you want to move up, you'd retrain and challenge the 313A exam.
What is the ODP card and do I need it?
The ODP card — formally the Environmental Awareness Course for Refrigerant Handling — is a federally required certification for anyone in Canada who purchases, handles, or services refrigerants. It's issued through HRAI, RSES, and other accredited bodies. Without it, you legally can't recover or charge refrigerant, which means you can't function as an HVAC technician. List it on your resume right after your trade ticket.
Do I need a gas fitter ticket for HVAC work?
For commercial and ICI work, almost always yes. Most commercial HVAC systems include gas-fired equipment — boilers, rooftop units, makeup air. In Ontario, G2 gas fitter (TSSA) is the common working level; G3 is entry, G1 is highest. In BC, Alberta, and other provinces, Class B is the working equivalent. Residential techs can sometimes get by with G3, but G2 opens up commercial work.
What's the difference between Alberta and Ontario for an HVAC technician?
Both provinces have compulsory certification for the trade. Ontario splits the trade into 313A and 313D codes — Alberta has a single Refrigeration and Air Conditioning Mechanic designation. Apprenticeship length is roughly similar (four years). Both lead to the Red Seal endorsement on passing the IP exam. The bigger practical difference is gas fitting — Ontario uses G1/G2/G3 through TSSA, Alberta uses Class A/B through Alberta Municipal Affairs.
Should I list specific equipment manufacturers on my resume?
Yes. Recruiters search for them by name. Trane, Carrier, Daikin, Mitsubishi, York, Lennox, Liebert, Vertiv, Mammoth, Aaon, Engineered Air all show up in job postings. If you've got manufacturer training (Daikin VRV certification, Trane TRACER controls, Carrier i-Vu) put it on the page. Same for BAS — Honeywell, Schneider, Johnson Controls, Distech, Reliable Controls.
