Plumber Resume Canada — 306A Journeyman Guide 2026

A plumber resume in Canada needs to show your 306A Certificate of Qualification, provincial registration, and the specific systems and project types you've worked on. Employers hiring journeyman plumbers in Ontario and across Canada screen for your licence before reading anything else — no licence, no further consideration. After that, commercial vs residential experience, gas licence, and specific system types are what separate candidates.

Provincial plumbing licences

Red Seal (Interprovincial Standards) allows you to work in any participating province without re-licensing. If you have a Red Seal, lead with it — it signals the highest tier of nationally recognized qualification.

Put it in your resume header:

Journeyman Plumber — Ontario 306A CofQ [Number] | Red Seal Holder

Gas fitter licence — a major differentiator

In Ontario, the Gas Technician 2 (G2) licence lets you connect gas appliances. The Gas Technician 1 (G1) licence allows installation and service of high-pressure gas systems. Holding a G2 or G1 in addition to your 306A significantly expands your employability and earning power — residential service companies often list it as a preferred or required qualification.

Other certifications to list prominently:

• 306A Certificate of Qualification — with CofQ number
• Red Seal (if held)
• Gas Technician 2 (G2) — with TSSA number (Ontario)
• Gas Technician 1 (G1) — with TSSA number (Ontario)
• Standard First Aid & CPR Level C
• WHMIS 2015
• Working at Heights — with expiry
• Backflow Prevention certification (if applicable)
• Cross Connection Control endorsement (Ontario — testing and device installation)
• Confined Space Entry
• Forklift (if applicable)

Commercial vs residential — two different resumes

Residential plumbers should emphasize: new home construction, renovation and service calls, fixture installation, drain, waste and vent (DWV) systems, gas line installation (G2/G1), customer communication, and solo service route work.

Commercial plumbers should emphasize: mechanical rooms, large-diameter piping (4" and above), grooved piping systems (Victaulic), high-pressure systems, blueprint/mechanical drawing reading, coordination with other trades, building code compliance, and working to specifications on commercial builds.

Writing strong plumber resume bullets

Weak: *Installed and repaired plumbing systems on construction sites.*

Strong: *Installed complete DWV, domestic cold/hot water and storm drainage systems for a 42-unit condominium tower in Mississauga — roughed-in 12 units per floor, coordinated stack connections with mechanical engineer drawings, and completed all work to Ontario Building Code standards.*

More examples:

• *Completed 6–8 residential service calls daily for a plumbing company servicing the GTA — handled drain cleaning, fixture replacements, water heater installs, and gas line connections (G2) with zero callback rate over 14 months.*
• *Coordinated rough-in plumbing for a 28,000 sq ft commercial renovation in downtown Toronto — read mechanical drawings, installed 3" and 4" cast iron and ABS systems, and completed work 2 weeks ahead of general contractor schedule.*

Salary in Canada 2026

Union rates (UA — United Association) are typically at the high end of these ranges with full defined-benefit pension and benefits packages.
