Speaking for the aerospace industry, YYZ isn't that bad comparing to YUL. Safran (landing gears), Honeywell (APU), Pratt-Whitney (engines), BBD (Dash 8), and a number of software companies, just to name a few. Speaking for universities, you can work in those companies with a degree in mechanical / electrical / computer engineering. Aerospace engineering is mostly for people designing the aerodynamic structures of the aircraft.
