Not necessarily the most "world renowned," because those are only few (Van, Toronto, Montreal, Edmonton). Where exactly would you want to live? What city do you believe has the most admirable attributes (least crime, pollution, best educational system, health care, etc)? Of course most of us have not been to or even know of the standards in some of these world class cities, so feel free to opine.
