The Toronto Star had an interesting article on the top six "mother-tongue" languages as reported in the 2001 Census for the GTA in the Saturday paper. Apparently in Mississauga, where I live, Polish is second after English closely followed by Chinese. I have an Italian friend in Vaughn where it is reported that almost 23% list Italian as their mother tongue. The demographics are quite interesting: I had the impression that certain nationalities gathered in certain regions and this article clearly demonstrates I wasn't mistaken.
