Sure, Trudeau was a ski instructor. You will also note that I neglected to mention that Poilievre had a paper route; that's because paper routes aren't professional experience.
Trudeau was also a secondary school teacher, acted in a tv movie. He also reputedly worked as a bouncer and worked in various (heavily politically affiliated) non-profits. He had a career before politics.
That said, my primary point is that Poilievre hasn't been a particularly effective politician, and his reputation is largely that of a blowhard who's main appeal is that he is not Trudeau.
