I'm not an AVN tech, but I did do the structures program at SAIT in Calgary.
SAIT was absolutely excellent, with top notch equipment, instructors, and facilities. A lot of the instructors were ex-military too, which should help. I paid for the program out of my own pocket, and it was worth every cent.
I can't speak highly enough about them.
I've done a lot of qualifications at a lot of different schools, and I can definitely say that out of the 6 colleges, universities, and medical schools I've been to, the aviation program at SAIT was the one who had their act together the most.
My 2 cents.
