Industrial Construction

No provincial trade licence required

Industrial construction — plants, refineries, mines, power, and process facilities — is dominated by certified trades, owner safety qualification systems (ISN, Avetta, ContractorCheck), and heavy welding and pressure-equipment compliance.

Industrial Construction at a glance

Licence to do the work
No single licence — TSSA, CWB, and owner safety systems govern the work
Path in
Via the certified trades (millwright, boilermaker, steamfitter) — largely union

Insurance baseline
$5M+ CGL, pollution liability common

The licensing layer, explained

No single provincial industrial licence, but the sector layers on heavy compliance: TSSA registration for boilers, pressure vessels, and piping; CWB/ASME welding qualifications; owner contractor-management systems (ISNetworld, Avetta, ContractorCheck); and frequently COR safety certification. Most trades on industrial sites are compulsory and union.

Certifications in this trade

Insurance to expect

Industrial owners demand high CGL limits ($5M+), pollution/environmental liability for many scopes, and registration in their contractor-safety platform before you can quote. Sudden-and-accidental pollution coverage is often specified.

The real picture

Industrial construction — plants, refineries, mines, power, and process facilities — is a world apart, and the questions reflect it: how owner safety-qualification systems (ISNetworld, Avetta) gate everything before you can even quote, why it's union- and certified-trade dominated, the shutdown/turnaround economics, and whether the pay and per-diem are worth the travel and the camps.

What you'll actually make

From day one to the top of the trade. Ontario figures, approximate and worth verifying against current rates.

  1. Certified trade on industrial

    Top union rates + shutdown OT

    Steamfitters, millwrights, boilermakers, electricians — among the best-paid hands in construction.

  2. Industrial PM / estimator

    $100k–150k+

    Running industrial projects and turnarounds.

  3. Industrial specialty contractor

    Business income

    A mechanical, electrical, or specialty sub on plant work.

  4. Established industrial contractor

    Large

    Owner relationships, certified crews, and safety qualification are the moat.

Which lane is right for you

How you get on an industrial site

Owner qualification (ISN / Avetta)

Most large owners require registration and a passing safety grade in a contractor-management platform (ISNetworld, Avetta, ContractorCheck) before you can even quote. No clean safety record, no bid.

Best for: Anyone wanting industrial work — it's the first gate.

Construction vs maintenance/shutdowns

New plant builds are steadier, project-length work. Maintenance and turnarounds are boom-bust: intense overtime, travel, and per-diem during a shutdown, then downtime.

Best for: Pick by whether you want stability or maximum-earning bursts.

What the work demands

Certified trades & welding

Compulsory trades (steamfitters, millwrights, boilermakers, electricians), CWB/ASME welding qualifications, and TSSA pressure-equipment registration. Industrial is heavily certified and largely union.

Best for: Tradespeople with the tickets and welding qualifications.

High insurance & pollution coverage

Owners demand high CGL limits ($5M+) and often pollution/environmental liability, on top of the safety-platform registration.

Best for: Contractors equipped for the compliance bar.

Getting in

Industrial isn't entered casually. You register in the owner's contractor-management system (ISNetworld/Avetta), build a strong documented safety record (usually COR®), carry high insurance and pollution coverage, and bring certified, qualified trades. Most contractors start as a sub to established industrial firms — and most workers arrive through the constituent certified trades (steamfitting, millwrighting, boilermaking) and their unions.

Where it leads (and the way out)

Scale, specialize into a high-value niche (pressure piping, millwrighting, instrumentation), or sell. Industrial contractors with safety qualification, certified crews, and owner relationships are high-value and hard to replace — those owner relationships and the safety record are the real, sellable assets.

Where the real conversations are

The communities, official bodies, and wage data tradespeople actually use.
