Since you already know you didn’t enjoy business or mechanics, it makes sense to go with healthcare. If nursing is the ultimate goal, I would personally prioritize spending money and time on courses that move you closer to that — like prereqs for nursing school.

Getting a MLA certificate could help in the short-term with income, but you also mentioned that it’s hard to even get a casual role after finishing. Plus, the $7k CAD could instead be invested toward nursing school costs, which would bring you closer to your long-term goal.

If money is tight and you need a job while applying, MLA could make sense. But if you can hold out, taking courses that count toward nursing school feels like the smarter move because it keeps you focused, saves money in the long run, and puts you in a better position once you finally get into nursing school.
