The Ghettoization of "Toronto the Good"?

The "elephant in the room" during discussions of most any socio-economic and demographic trend relating to Toronto is the growing geographic, ethnocultural, and skin colour (white, non-white) polarization of the city.

Is Toronto creating its own version of ghettos? If so, they will not be American style ghettos. Those arose from U.S. specific historical circumstances and at a different time.
