Plumber
A day looks like: Installing and repairing water, drainage and gas systems in homes and commercial buildings; paid on-the-job hours plus in-school blocks.
What stops people: Sponsoring employer, same as most construction trades.
Downside: Physically hard on knees and back over decades. Emergency and weekend calls are part of the job.
Truck and coach technician
A day looks like: Diagnosing and repairing trucks, buses and coaches in a fleet or dealer shop: brakes, air systems, diesel and increasingly electric drivetrains, with eight weeks a year in trade school.
What stops people: Landing a sponsoring shop (fleet, transit agency, dealer) before you can register. A G licence and a Grade 12 math credit help.
Downside: Heavy, dirty and often shift work. You buy your own tools. Diesel and electric drivetrains are both changing fast, so the learning never stops.
