Hi,
I have done most of my flying out of Boundry Bay airport and worked with most of the schools there.
DO NOT choose professional Flight Center! The owner is on par with a used car salesman. He is in the business of making money. Period. They will try to get every cent out of you by having you fly as much as they can even when it is not necessary. Once you are there flying, they don't care about you at all. Pure money grab. STAY AWAY!
At Boundary Bay I would recommend Pacific Flying Club or Canadian Flight Center. Pacific Flying Club is a non profit organization, so they are not trying to milk you for every dollar.
My number one recommendation is Pitt Meadows. Try one of the small schools there. The owners actually care about providing quality flight instruction. The airport is closer to the practice are which means shorter flight times which saves you money. The cost of living in Pitt Meadows is also much cheaper.
I live in Osaka and did all of my flight training in Canada. Feel free to drop me a line anytime to ask any questions.
