Welding Jobs in Ontario: Top Opportunities, Certifications & Salary Guide 2026

Welding is one of the most versatile and in-demand skilled trades in Ontario. From structural steel on construction sites to precision pipe welding in industrial facilities, welding jobs in Ontario span every sector of the economy — and 2026 is seeing particularly strong demand.

Here's your guide to the welding job market in Ontario: what's driving demand, what you can earn, which certifications matter most, and where to find the best opportunities.

Why Welders Are in High Demand in Ontario

  • Infrastructure construction: Transit projects, bridges, highways, and public buildings all require extensive structural steel welding.
  • Industrial expansion: Battery manufacturing plants, data centres, and processing facilities in southern Ontario need welders for fabrication and installation.
  • Manufacturing sector: Ontario's manufacturing base — automotive, aerospace, heavy equipment — relies heavily on skilled welders.
  • Energy sector: Pipeline maintenance, power generation facilities, and renewable energy installations require specialized welding skills.
  • Mining and resources: Northern Ontario's mining sector demands welders for equipment maintenance, fabrication, and construction.
  • Workforce shortage: Like many trades, welding faces a significant retirement wave, creating openings for new and experienced welders alike.

    • Types of Welding Jobs in Ontario

    Structural Steel Welder

    Work on building frames, bridges, and other structural projects. Typically involves MIG and stick welding of heavy steel sections. Often requires working at heights and reading structural drawings.

    Pipe Welder

    One of the highest-paying welding specializations. Work on piping systems in industrial facilities, power plants, hospitals, and commercial buildings. Requires proficiency in TIG and stick welding, often on exotic materials (stainless steel, Inconel, etc.).

    Pressure Welder

    A step above standard pipe welding. Work on boilers, pressure vessels, and high-pressure piping systems. Requires specific certifications and is among the highest-paid welding roles.

    MIG/MAG Welder (Production)

    High-volume welding in manufacturing settings. Automotive parts, heavy equipment, structural components. Often involves robotic welding cells with manual supplementation.

    TIG Welder

    Precision welding for aerospace, food processing equipment, pharmaceutical systems, and architectural metalwork. Requires high skill levels and attention to detail.

    Field Service Welder

    Mobile welding for repair and maintenance work. Often involves emergency calls, on-site fabrication, and working in varied conditions. Can be very lucrative for experienced welders.

    Welding Inspector

    A career progression role. Inspect welds for quality and code compliance. Requires CWB or CWS certification and significant welding experience.

    Salary Ranges for Welders in Ontario (2026)

    Role Entry-Level Mid-Career Senior/Specialist
    General Welder (MIG/Stick) $22–$28/hr $30–$38/hr $40–$48/hr
    Structural Steel Welder $24–$30/hr $32–$42/hr $44–$54/hr
    Pipe Welder $28–$36/hr $38–$48/hr $50–$62/hr
    Pressure Welder $32–$40/hr $42–$52/hr $54–$68/hr
    TIG Welder (Precision) $24–$32/hr $34–$44/hr $46–$58/hr
    Welding Inspector (CWB/CWS) $35–$45/hr $48–$58/hr $60–$75/hr
    Field Service Welder $28–$36/hr $38–$50/hr $52–$70/hr

    Many welding roles include overtime, travel pay, and per diems for remote work. Northern and fly-in positions often pay significant premiums.

    Essential Welding Certifications in Ontario

    CWB (Canadian Welding Bureau) Certification

    The industry standard for welders in Canada. CWB certification demonstrates that you can produce welds meeting Canadian standards. Key certifications include:

  • CWB CSA W47.1 — Fusion welding of steel
  • CWB CSA W47.2 — Fusion welding of aluminum
  • CWB CSA W55.3 — Resistance welding
  • Process-specific certifications: MIG, TIG, Stick, Submerged Arc

    • B-Pressure Welding Certification

    Required for welding on pressure vessels and boilers in Ontario. Issued by the Technical Standards and Safety Authority (TSSA). Highly valued and well-compensated.

    ASME Section IX

    International standard for welding procedure and performance qualification. Required for many industrial and power generation projects.

    API 1104

    Standard for welding of pipelines. Required for oil and gas pipeline work.

    AWS (American Welding Society) Certifications

    While Canadian-focused, AWS certifications (CW, CWI) are recognized by some employers, particularly those with US operations.

    Additional Valuable Credentials

  • Working at Heights: Required for structural and construction welding.
  • Confined Space Entry: Needed for tank and vessel work.
  • WHMIS 2015: Mandatory on virtually all job sites.
  • First Aid/CPR: Often required, especially for field service roles.
  • rigging and hoisting: Useful for structural welders.
  • NDT (Non-Destructive Testing) awareness: Understanding of UT, RT, MT, PT inspection methods.
