What ironworkers make in Ontario

Ironwork carries the most mythology and the most real danger of the trades, and the questions are honest about both: is it as dangerous as they say, structural vs rebar vs ornamental, is the union the only real way in (mostly yes), and how the welding ticket multiplies your pay. It's high, it's hard, and it pays accordingly — and almost everyone respects the people who do it.

Ontario figures for structural steel, from the first day on site to the top of the trade. Approximate, and worth checking against current collective agreement rates and job postings in your region.

The lanes that pay differently

Two ironworkers with the same ticket can be twenty dollars an hour apart because they picked different work.

Structural (420A)

Top of the trade.

Erecting the steel skeleton — high steel, connecting, raising gangs. The dangerous, iconic, well-paid end; connectors are the elite.

Best for: People with a head for heights and nerve.

Reinforcing / rodwork (452A)

Steady.

Rebar and post-tensioning — ground-level, bent-over, hard on the back, but steady and a more accessible entry.

Best for: People who want ironwork without the high steel.

Ornamental

Varies.

Railings, stairs, curtain-wall steel, and architectural metal — finish-end and fabrication-adjacent.

Best for: People who like detail and fabrication.

The wage is not the rate

Every figure above is what ironworkers get paid. It is not what you charge once you run a structural steel business. Your rate has to carry the hours you are not on the tools, the truck, the tools themselves, WSIB, insurance, the quote you wrote and lost, and the holdback sitting in someone else's account for 60 days. Contractors who set their rate off their old hourly wage are the ones who work every weekend and still cannot say whether the year was profitable.

The step from paid by the hour to paid by the job

Where the money goes after the tools

The danger and the body make the exit ramps important: foreman and superintendent, steel detailing and estimating, welding inspection (CWB), safety, or owning an erection/miscellaneous-steel shop. Many ironworkers move into supervision, the fabrication shop, or inspection as the years (and the heights) add up. Welding inspection in particular is a respected, well-paid landing off the steel.

What sets the rate
