and not really because of Trump’s tariffs, but rather the very high taxes, regulations, and lots of wasteful government spending

Oooh you're really going to have trouble on here as a Conservative. I won't even argue; you'll get enough of that.

I will say our economy is roughly static right now, not falling, because that's relevant to your decision, and easy to look up if you don't believe me.

However, I did hear that the automotive mechanic trade is pretty recession-proof (because people will still need their cars fixed even in a recession and will be less likely to buy a new car).

Goes for any emergency repair-type business, really, so keep that in mind. Low-end stuff also benefits during a recession, and anything maintenance-based should hold steady, including first responders or (relevant for Canada right now) the military. What suffers a lot is luxuries, new projects and basic industries that feed into many other things that are slowing down.

Is there another reason you want to do automotive? You spend too much time at work to pick something that doesn't hold your interest at least a bit.

I just thought that taking the Automotive Technician would really improve my chances of getting into the trade because I just don’t have any previous work experience.

Yes, it would. Canada is actually the most educated country in the world by far, and has a bad credentialism problem. Almost any industry is going to covet more education, and you'll see people doing the exact same job for a lot more because they have some kind of diploma.

On the other side, I know tons of people with a degree they're never going to use, or at the very least aren't going to use for that actual field.
