Air traffic controller (NAV Canada)
A day looks like: Online aptitude tests and an assessment centre, then one to two years of paid classroom and simulator training, then live traffic under supervision in a tower or area control centre.
What stops people: Roughly one in a hundred applicants is accepted into training, and under half of trainees graduate. Failing a stage can mean a multi-year wait before you can reapply.
Downside: Rotating shifts for a career, relocation to wherever the opening is, and a training wash-out rate that would be unacceptable anywhere else. Not a fallback plan.
Correctional officer
A day looks like: Supervising inmates in provincial institutions; unionised with a pension.
What stops people: Must be 18, pass fitness and background checks, and get through a competitive intake.
Downside: Stressful, sometimes dangerous, with shift work and high burnout.
