The work

What this job actually is

  • Working out how something moving, heating, cooling, bearing a load or being made should work, and then proving it does.
  • It covers a huge range: factory production lines, vehicle parts, heating and cooling systems, power equipment, medical devices. What you do depends heavily on the employer.
  • A great deal of the day is calculation, drawing, modelling, testing, and meetings about why a prototype failed.
  • Engineers work in teams alongside technicians, tradespeople and suppliers, and a design nobody can build or maintain has failed whatever the maths says.
  • Once licensed, you take legal responsibility for what you approve. That responsibility is a big part of what the licence means.

A Tuesday

What a normal day looks like

Not a good day or a bad one. The ordinary version, which is what you would actually be living.

  1. 8:00 — Check the test results from last night. The bracket survived the load but one weld cracked.
  2. 8:45 — Meet the shop-floor supervisor to see the cracked part. They tell you something about how it is made that nobody wrote down.
  3. 10:00 — Update the model in the design software to move the stress away from that weld.
  4. 11:30 — Run the calculation again, then again with a bigger safety margin.
  5. 12:30 — Lunch. Somebody argues that the old design was fine. Maybe it was.
  6. 13:15 — Meeting about cost. The better part is more expensive and you need to explain why it matters.
  7. 14:30 — Draw up the change so it can be made, checked and approved. Every dimension has to be right.
  8. 15:45 — Write the test plan for the new version: what will count as a pass, and who will check it.
  9. 16:30 — Review a colleague's drawing and find an error in a tolerance that would have cost a week.
  10. 17:00 — Sign off for the day. The part still has to be built and tested before any of it is real.

Honestly

Who loves this, and who should not do it

The second list is the useful one. Nearly every careers page leaves it out, which is why nearly every careers page reads like an advert.

You may like this if
  • You like working out how things move, fit and fail.
  • You can do careful calculations and also stand next to a real part and handle it.
  • You are comfortable being responsible for something other people depend on.
  • You like maths and physics when they are used for something.
  • You can explain a technical choice to people who care about cost and schedule.
You may hate this if
  • You dislike long stretches of detailed calculation and checking.
  • You want a job market with plenty of openings. Job Bank rates the 2025-2027 Ontario outlook for this occupation as Limited.
  • You do not like accountability. A mistake can have serious consequences and your name is on the drawing.
  • You want to be hands-on all day. Many engineers spend most of the day at a computer.
  • You dislike regulation and paperwork. Licensing, standards and sign-offs are part of the job.

The route in

How you actually get there in Ontario

  1. Know what the outlook says

    Job Bank rates the 2025-2027 Ontario outlook for mechanical engineers as Limited. It says employment decline will lead to the loss of some positions, not many positions will become available through retirements, and there are a moderate number of unemployed workers with recent experience. It points to weak business conditions in manufacturing, particularly automotive production, while noting a shift to more advanced processes including robotics, and that investment in the province's energy grid should create some opportunities. Engineers who can work across industries are better placed than those tied to one.
  2. Earn an accredited engineering degree

    Professional Engineers Ontario (PEO) says the academic requirement for a P.Eng. licence is a bachelor's degree in an engineering programme accredited by the Canadian Engineering Accreditation Board, or a degree on PEO's Recognized Programs List plus a technical exam programme. Many Ontario universities offer co-op, which lets you work in industry before you graduate.
  3. Work under licensed engineers and document your competence

    PEO assesses experience through a competency-based assessment with 34 competencies across seven categories, and requires at least two years of eligible, verifiable experience, beginning when a recognized four-year Bachelor of Engineering degree is conferred. PEO says applicants on average need three to four years to show all the competencies. PEO does not require Canadian experience. Co-op work before graduation does not count toward the two years, though it may help with the assessment if it meets the criteria. These rules were updated on 1 July 2026, so check PEO's page.
  4. Apply for the P.Eng. licence

    PEO's requirements also include a good character assessment and identification. Job Bank adds that professional licensure is compulsory in Ontario to approve engineering drawings and reports, and that the pathway includes passing a professional practice examination. In the meantime you can work as an engineer-in-training under a licensed engineer.

Where it is heading

The outlook for the next three years

Job Bank publishes a three-year outlook for every job in every province. It is the closest thing to an honest forecast, and it moves, so read it as a weather report rather than a verdict.

Ontario, 2025-2027

Limited2 out of 5 stars

  • Employment decline will lead to the loss of some positions.
  • Not many positions will become available due to retirements.
  • There are a moderate number of unemployed workers with recent experience in this occupation.

What that rating means: how many openings Job Bank expects in Ontario for this kind of work against how many people are likely to be looking — not whether it is a good job. A “limited” rating means more competition for each opening; it does not close the door, and it can change before you are ready to walk through it.

What is changing in this work

  • Shift towards more advanced processes in manufacturing, including new production lines and use of robotics
  • However, job prospects are expected to be moderated due to weak business conditions in the sector, particularly in automotive production
  • Investments in the province's energy grid should create some job opportunities

Who hires for it

  • The leading share employed in manufacturing, especially transportation equipment and machinery production
  • Professional, scientific and technical services industry, largely architectural, engineering and related services
  • Utilities, mostly electric power generation

Before you leave school

Things you can do now

  • Take the highest maths and physics you can, plus any technology or design courses. Engineering degrees ask for these in Grade 12, and checking the university requirements by Grade 10 keeps options open.
  • Look for a robotics club, a design competition or a school shop. Building something that has to work is the best preview.
  • Ask about co-op placements in a workshop or manufacturing business.
  • Look at the entry requirements and co-op options of two Ontario engineering programmes on ontariouniversitiesinfo.ca.

Test it

Do this before you decide anything

Reading about a job tells you almost nothing. This is designed to be done alone, this week, for free.

Take a simple mechanism apart and work out why it works

About 90 minutes
  1. Choose something mechanical that is not plugged in and has no battery, such as a stapler, a door latch or a bike brake lever. If something has a spring under tension, leave it alone.
  2. Sketch it before you open it, then take it apart slowly, laying the pieces in order. Draw how the force travels from your hand to the result.
  3. Find the one part you think is the weakest and write what would happen if it was made from something cheaper.
  4. Put it back together. Note whether it worked afterwards.

What it tells you. If you were more interested in why the parts were shaped that way than in the satisfaction of opening it, engineering is a good bet. If you enjoyed the taking apart but lost interest at the drawing and reasoning, the hands-on trades or a technologist route may suit you better. If you could not work out how the force travelled, that is a normal start, but notice whether you wanted to find out.

Questions for somebody who does this job

Most people say yes to a teenager who asks good questions. These are the ones that get real answers rather than encouragement.

  1. “What did you design or check this week, and who built it?”
  2. “How did you get your first engineering job, and was co-op important?”
  3. “What does signing off a drawing feel like?”
  4. “How long did your P.Eng. take, and what slowed you down?”
  5. “What would you want a student to know about the industry's job market right now?”
  6. “What part of the degree did you actually use?”

Could you own one of these?

The part other career sites never mention

Yes, but usually later. Some engineers go independent as consultants, and a licensed engineer can offer services to the public. It generally follows years of experience and the P.Eng. licence, because clients are paying for your judgment and your signature. Early on, working under licensed engineers is how you build both.
