I find that there a few habituated ones in High Park (near Colborned Lodge, many people feed them off the roadside barrier) as well as in the RBG area (especially the wetland trails behind the RBG - Cheery Hill Gate trail head - , also chipmunks, nuthatches, chickadees, blue jays - many of these will feed off your hand).
I'm sure others have their own spots they can relate.
