Again, I'm not much use on legal issues, but I can tell you a little bit.
While I was in the process of transitioning, I was taking an extra professional degree, and the bathroom issue was a big issue. Classes were three hours long. I can't last that long; I'm old. There weren't any non-gender-specific bathrooms anywhere, without walking outside the building and going around the corner to a restaurant.
This was a building with five floors. On every floor there was a men's bathroom and a women's bathroom. A group of us went to the university—this was the University of Toronto—and asked if we could have one floor where you could have, instead of a men's washroom and a women's washroom, two pieces of plastic that said “all-gender washroom”, one on each washroom. All of the other bathrooms on the other floors could stay exactly the same.
After enormous debate that went on and on, they decided that it was absolutely impossible.
If we'd had this kind of legislation where we could say, “Look, the Government of Canada says you're not allowed to discriminate, and the way these bathrooms work now discriminates against us in this really powerful way; look at this document”, I believe it would have made a difference. I do.
