CYOO added a $15 landing/touch and go fee, and lots of rules about curfews/long weekend flying and seems to just hate that GA operates there. Buttonville has closed down lowering options.
YTZ has a severe shortage and has operated as a MF on long weekends due to controllers not showing up, no complaints about the school but over $300 an hour for dual in a 150!
Nav Canada refuses to let planes transit the zone, bans IFR practice approaches by NOTAM on weekends and other busy days, and effectively says you're on your own.

There are so many obstacles that haven't really existed in the past, I wonder what people are doing to get their licenses?
