Well, I don't want to repeat what the Montreal Economic Institute has already articulated.
I've been studying professional associations, and there's an incredible breadth and complexity. There are a lot of differences in how they're structured. I don't know that there's a professional association in this country that wants to be called a union. When you read the academic literature, that's one of the things it talks about. They are very different entities that serve a regulatory or quasi-regulatory purpose.
The UFCW doesn't make sure how a grocery store worker stocks employees, but the Law Society focuses on how a lawyer practises law. They're very different organizations. The bar associations do the political stuff, the non-regulatory stuff.
Those are the important differences.
