Again: what does any of this have to do with labor laws? I get that you're just responding to the comment there, but you kind of started this thread with your "you know, YC" thing, and it's still totally unclear what any of this has to do with operating a company in Canada. You can still operate YC companies in Canada!
Ah, see. Here's the problem. Yes: you misread the OP. You've misunderstood what's happening here. YC still funds Canadian startups. They don't have to move. They retain their Canadian HQ. Their operations remain in Canada.
