LOL, I love this, I am even surprising Canadians with Canadian issues.

They had past the legislature when I was in highschool...it was a pretty big deal, I am surprised you didn't know. Maybe it was at the provincial level only (thus, for certain, in Ontario), although I thought it was federal. If you have been to Toronto you will see these nasty ladies walking the sidewalks completely topless. Honestly, the first time I saw one I thought it was a man.

But, I can't say it's common, I see one a summer max. Too much, I'd say.
