Yes indeed, I have my full Permanent Resident Status, and married to a Canadian girl. I lived in Canada for nearly 4 years where I started my Aviation training, and have a Canadian PPL, New Zealand PPL and a JAA ATPL with B757/767 and B737-300 to -900 type ratings.
Moving over here is not a decision I'm making lightly, but one I am very much interested in.
For anyone else interested in the answer to where Westjet base their pilots, I just got off the phone to a nice lady in the recruitment department who told me that all pilots are based in Calgary, but many pilots commute at their own expense.
