4 year degree then flight training
All the more reason you should get your degree in Canada - then do your flight training in the US.
Degree first then flight school in the states...Work when in school and especially the summers - put the money away so you can make a bigger downpayment on your loan.
Depending on what you make while in school I would look into putting money into a index fund. I recommend the Vanguard S&P 500.
