I went to Toronto Airways to get my PPL. It was a pretty good school though I don't have anything to compare it to. I've flown out of City Centre airport and their school seemed a little less professional, and they're super busy with Porter. Toronto Airways is now at Oshawa Airport which is a far drive from Toronto. However when I was doing my PPL at Toronto Airways they were training China Southern pilots, not sure if they're still doing that but I'm sure they're doing something right.
