What Does an Ironworker Do?
Ironworkers — also called structural iron and steel workers — are skilled tradespeople who install, connect, and erect structural steel frameworks for buildings, bridges, and other large structures. Their work includes reading blueprints, rigging and hoisting steel beams, bolting and welding connections, and ensuring structural integrity at great heights.
Key responsibilities include:
- Reading and interpreting structural drawings and blueprints
- Rigging, hoisting, and positioning steel beams and columns
- Bolting, welding, and riveting steel connections
- Operating cranes and hoisting equipment
- Working at heights on scaffolding, lifts, and steel frameworks
- Inspecting and reinforcing existing steel structures
- Following strict safety protocols and OHSA regulations
Ironworkers are essential to every major construction project in Ontario. Whether it's the LRT expansion in Ottawa, condo towers in Toronto, or hospital builds across the province, structural steel workers form the backbone of commercial and infrastructure construction.

Certification & Training Requirements
Becoming a certified ironworker in Ontario requires a combination of classroom training, on-the-job apprenticeship, and industry certifications. Here's what you need:
Ironworker Apprenticeship Program
Ontario's ironworker apprenticeship is a 3-year (6,000-hour) program administered by the Ministry of Labour, Immigration, Training and Skills Development. Apprentices complete approximately 900 hours of in-class training per year at an approved college, combined with paid on-the-job training under a journeyperson.
Apprenticeship wages start at roughly 50–60% of the journeyperson rate and increase with each period completed. Upon finishing all three periods and passing the Certificate of Qualification exam, you earn your Red Seal endorsement, which is recognized across Canada.

Frequently Asked Questions
How much do ironworkers make in Ontario in 2026?
Entry-level ironworker apprentices earn $28–$35/hour ($58K–$72K annually), while experienced journeypersons earn $46–$55/hour ($95K–$113K). Foremen and lead hands can exceed $120K with overtime and benefits.
Do I need a Red Seal to work as an ironworker in Ontario?
A Red Seal is not legally required to work as an ironworker in Ontario, but it is highly recommended. Most union employers and major contractors require or strongly prefer Red Seal-certified workers. It also allows you to work in any Canadian province without re-certification.
How long does it take to become a certified ironworker?
The apprenticeship program takes approximately 3 years (6,000 hours of on-the-job training plus 2,700 hours of in-class instruction). Some workers with prior welding or construction experience may be able to challenge the certification exam earlier through trade equivalency assessment.
Is ironworking dangerous?
Ironworking is classified as a high-risk trade due to work at heights, heavy materials, and exposure to weather. However, Ontario's strict OHSA regulations, mandatory Working at Heights training, fall protection systems, and union safety programs have significantly reduced incident rates. Proper training and PPE are essential.
What's the difference between an ironworker and a welder?
Ironworkers focus on erecting and connecting structural steel frameworks — reading blueprints, rigging, bolting, and positioning beams. Welders specialize in joining metal through various welding processes (MIG, TIG, stick). Many ironworkers hold welding tickets, and the trades overlap on job sites, but they are distinct classifications with separate apprenticeship programs.
