@CathyMik Hey! I've lived in a few areas of Toronto and I've got friends all over it. Not super familiar with the area up by Yorkdale (that's the one, right?) but I've heard good things about Yonge & Eg, Keele station (though in winter it's a slog!), the annex (though it's a lot of student housing / rich people right now), and the west end around the Dundas car.
I'm most familiar with the downtown core, though it's super expensive now, so you kind of have to pick your battles. The gaybourhood is still great, and there are lots of new condos and apartments going up all the time, as well as more Ryerson residences.
Good luck with your potential move!
