Choosing a trade

Most “best trades” lists rank by salary. Salary is the least useful axis, because the spread within a trade — union versus non-union, city versus remote, employee versus owner — is wider than the spread between trades.

Rank on these instead.

The five axes that actually decide it

1. Body load. How much of your body are you spending, and how fast? Roofing, drywall finishing, concrete and framing are high-wear. Instrumentation, elevator, controls, appliance service and inspection are low-wear. This is the axis that decides whether you are still doing this at fifty-five, and it is the one career-change posts most consistently ignore.

2. Cognitive load. Some trades reward diagnosis and system thinking; others reward speed and repetition. Coming from software you will be much happier in a diagnostic trade even at lower pay, because a boring trade is far harder to endure than a boring desk job — you cannot open another tab.

3. Weather and travel. Outdoor construction in a Canadian winter is a different job from the same trade indoors. Ask whether the work is seasonal, whether layoffs between projects are normal, and whether the good money requires camp work or shutdown travel.

4. Entry difficulty. Wildly variable and rarely correlated with pay. Elevator is famously near-impossible to enter and extremely well paid. Labourer is trivially easy. Some trades let you certify first and get hired after; most require a sponsor first.

5. Ceiling and exit. Where does this trade go at forty-five? Service and diagnostic trades convert well into supervision, inspection, teaching and business ownership. Ask what the fifty-year-olds in the trade are doing, and whether you would want that job.

A rough map

Not rankings — a starting shortlist to research properly, chosen for people arriving from a technical desk job. Verify wages for your own city by NOC code on Job Bank, and check the local outlook before you fall in love with a number.

Trade	Body load	Diagnostic?	Notes for ex-developers
Instrumentation and control technician	Low–moderate	Very high	Calibration, loops, PLCs, documentation. The closest Red Seal trade to engineering work. Industrial, often shift or shutdown.
Industrial electrician	Moderate	High	Motor control, VFDs, PLC troubleshooting. Indoors, plant-based, strong ceiling.
Construction electrician	Moderate	Moderate–high	The most common entry point; compulsory almost everywhere, so the ticket is the job. Broadest employment base.
Refrigeration and A/C mechanic	Moderate	High	Thermodynamics, controls, service calls. Year-round demand; strong path to your own service business.
Industrial mechanic (millwright)	High	High	Precision alignment, vibration, bearings. Excellent plant careers; hard on the body.
Powerline technician	High	Moderate	Excellent pay, utility employment and pensions. Genuine height and hazard exposure.
Elevator (elevating devices)	Moderate	Very high	Networked control systems. Not Red Seal; union intake is the gate. Apply early and repeatedly.
Machinist / tool and die	Low–moderate	High	CNC, CAM, tolerances. Shop-based, indoors, and unusually compatible with a programming mind.
Sheet metal worker	Moderate–high	Moderate	Layout and fabrication maths. Strong union training in most provinces.
Plumber / steamfitter	Moderate–high	Moderate	Compulsory in many provinces, always in demand, clearest self-employment path.

And the ones to look at outside the Red Seal list — power engineer, NDT technician, building automation, water/wastewater operator — which often let you certify first and get hired after, inverting the hardest step.

Questions to ask before committing

Ask these of a working journeyperson, not a recruiter or a college admissions officer:

• What does a bad day look like? A bad year?
• What is actually wearing out on you?
• How many of the people you started with are still in the trade?
• Who are the good employers here, and who churns apprentices?
• If you had to start again, would you pick this trade?
• What do the fifty-five-year-olds in this trade do all day?

How to actually decide

1. Shortlist three trades on the axes above.
2. Read all three Red Seal Occupational Standards end to end. This eliminates one immediately.
3. Do the sample exam questions for the remaining two.
4. Spend a day on site with each if you possibly can. A supply house, a temp shift, a friend of a friend.
5. Check the local Job Bank outlook — good pay with a poor local outlook is a relocation decision, not a career decision.
6. Then commit properly. Trade-hopping in year one costs you the hours you already logged.
