Is Toronto more of a "doughnut" city or a "wedge" city?

[Docere]

Is Toronto's economic geography more of a doughnut pattern, where you have a gentrified core surrounded by a poorer ring then surrounded by more affluent suburbs, or is it more of a "wedge" pattern where you have you have more working class and more affluent sectors running out of the core and into the suburbs.

On the one hand, Toronto does have a core/periphery pattern; on the other hand the "favored quarter" has traditionally run north of the city center.
