>Oh, we have our share. Toronto is a mecca for both illegal and legal immigrants. There was a news story just today that said that over 50% of all Torontonians were born outside of Canada (and only a very small percentage of those are from the U.S.). The actual City of Toronto is right around 50%. And I'm loving it.

It is not comparable in many ways. I recommend reading this:
