Just for clarification, do you mean you were astounded by the amount of ads in Toronto? Or in the US?

> I don't know much about the current status in the U.S., but Ontario at least seems to be completely infected by gambling ads.

I just live in a small farm town, so I'm not really exposed to ads or billboards in my daily life. Online gambling ads aren't in our local newspapers yet, at least.
