One of the reasons I love Toronto. While some revues are stronger than others, it is always a great time with terrific talent. Comedy is exceptionally difficult to do well and 2nd City consistently delivers.
I completely disagree with an earlier poster about the quality of Toronto relative to Chicago. I've seen 5 shows in Chicago and would say one was head and shoulders above anything I've seen in Toronto while 3 were inferior and one was at par. It really depends on the revue or show you are seeing.
