Welding Licensing in Quebec

Welding in Quebec does not require a specific provincial licence for individual workers. However, on regulated construction sites (governed by Act R-20), welders must hold a CCQ occupation competency certificate. In Quebec's construction industry, welding is classified as a specialized occupation (not a trade), so workers hold an occupation competency certificate rather than a journeyman competency certificate. A Diploma of Vocational Studies (DEP) in welding and fitting is also available. For structural and pressure vessel work, certification through the Canadian Welding Bureau (CWB) under CSA W47.1 or W47.2 is typically required. CWB welder qualifications must be renewed every two years. Red Seal endorsement is available for interprovincial mobility.

Ask if they hold a CCQ competency certificate or CWB certification. For structural work, CWB certification is essential.

(1) No CWB certification for structural or load-bearing welding work (2) Welds without proper fire safety precautions (no fire blanket, extinguisher, or safe perimeter) (3) Cannot specify the welding process or filler material they will use for your project (4) Poor-quality welds visible in their portfolio (excessive spatter, uneven beads, undercut) (5) No liability insurance - welding involves fire risk and potential property damage

(1) What welding certifications do you hold (Skilled Trades Ontario, CWB, Red Seal)? (2) What welding process will you use for my project, and why is it the right choice? (3) Do you carry liability insurance? (4) What finish options do you offer for weather protection (paint, powder coat, galvanizing)? (5) Can I see photos of similar projects you have completed?

While not legally required, it is strongly recommended that weldings carry liability insurance. Ask for proof of coverage before hiring.

The Red Seal endorsement is a nationally recognized certification that allows tradespeople to work across all Canadian provinces and territories without additional testing. A Red Seal-endorsed tradesperson has met a standardized level of competency.

In Quebec, most contractors performing construction work must hold an RBQ (Régie du bâtiment du Québec) licence. You can verify any contractor's licence on the RBQ's online Licence Holders' Registry at rbq.gouv.qc.ca. Always ask for the licence number and verify it before hiring.

Typical rates for weldings in Quebec range from $75-$150/hour. Type of welding required (MIG, TIG, stick, or specialty processes), metal type (mild steel is cheapest, stainless steel and aluminum are more expensive), complexity and precision of the work, whether the project is fabrication (shop work) or repair (often mobile), material costs (steel prices fluctuate), finishing requirements (grinding, powder coating, galvanizing), and location (mobile/on-site service includes a trip charge). Custom artistic metalwork and architectural pieces command premium rates.
