There are also 2-3 "good" blog reviews you can find that are very clearly fake (look at the comments).
I would proceed with caution, but if you paid already, I guess you don't have much choice.
I don't want to say more since I don't have personal experience with the school.
Unfortunately I don't know any other school at Chilliwack. I have flown there a few times, though, and it's a nice airport. Definitely not as busy as Vancouver.
