Skilltrade Ontario | What Are the Top Skilled Trades in Ontario and Their Codes?
Whenever someone talks “skilled trades” in Ontario, there’s a whole vocabulary flying around—sometimes regional, sometimes the industry’s own jargon. Here are 15 of the most popular trades and official code Skilltrade Ontario numbers:
Trade Name | Code |
Industrial Mechanic Millwright | 433A |
Automotive Service Technician | 310S |
Construction Electrician | 309A |
Plumber | 306A |
Sheet Metal Worker | 308A |

Introduction: Skilltrade Ontario Exam—Why It Matters
Let’s be honest—whether you call yourself a “Carpenter,” “Carpentry Pro,” or “Cabinetry Specialist,” people know you by the trade, not the title. Ontario sometimes throws curveballs on phrasing. “Automotive Service Technician” becomes “Auto Mechanic” at some shops; “Plumber” can be “Pipefitter” if you squint hard at a job listing. Ask a millwright about their gig and you’ll hear “Industrial Mechanic” just as often as the official title.
Restaurants want “Cooks” and sometimes list “Culinary Tradesperson.” Electricians are “Sparky,” “Wireman,” “Domestic electrician,” or “Construction Electrician” (code 309A). Hair stylists? “Barber,” “Salon Professional,” “Hairstylist.” You might see “Welder” called “Fabrication Specialist,” or “Sheet Metal Worker” referred to as “HVAC technician.” Employers list jobs as “Technician,” “Installer,” or “Assembler” depending on region. Even “Truck and Coach Technician” is just “Heavy Vehicle Mechanic” in some circles.
In short: the Skilltrade Ontario Exam covers dozens of trades, each with their own slang and titles—so don’t be confused by terminology! Study materials from CourseTree Learning use all the common terms and acronyms so nothing gets lost in translation.
There’s a reason the exam is a make-or-break moment—employers, unions, and the province want people with up-to-date, proven, hands-on know-how. Passing means you’re trusted, employable, and future-proofed.
Exam Challenges According to Students | Skilltrade Ontario
“Asif” on Practical Application: “I knew all the textbook answers, but the questions asked how to fix a real broken circuit, not just label the diagram. I had to use actual troubleshooting, not just memorize terms.”
“Megan” on Time Management: “You get swept up in wording, and suddenly you have five minutes left and ten complex multiple-choice questions to go. The stress is real! Practice exams helped me build speed.”
“Jon” on Standards and Codes: “Ontario standards aren’t always what I learned at work, so you have to study the official provincial guides, not just what the foreman taught you.”
Sometimes exams surprise you with unexpected theory, standards that differ by region, and scenarios demanding more than memory—be ready to adapt!

Title & Credentials: Trades Instructor, Skilltrade Ontario:
Dr. Thompson writes, “During my early years, I focused heavily on theory, thinking it was enough. Facing my first exam, I realized practical skills were key—solving real-world problems, not just reciting facts. It was a wake-up call; applied knowledge matters more than memorization.” CourseTree Learning’s resources reflect this philosophy—integrating hands-on scenarios, critical thinking, and lived experience.

Applied Knowledge: Example Procedure (Plumber/Hot Water Heater Installation)
Let’s walk through a common scenario—installing a residential hot water heater. First, shut off the water supply at the main valve and turn off power or gas to the old heater. Next, disconnect inlet and outlet pipes using a wrench, removing fasteners and unions. Carefully drain any remaining water and detach the heater. Position the new unit, secure it with anchors, and join copper or PEX pipes using proper joints. Solder or crimp connections for a leak-free seal; tighten unions and test with water running. Connect the temperature and pressure relief valve, and ensure the exhaust (gas units) or electrical panel (electric units) meets code. Start up the heater, check for leaks, and verify the water temperature. Document the installation, explaining warranty to the client. Always follow Ontario safety codes—inspect twice, install once!
