It went ok, first I went to the Calgary intl airport hoping it would save me a lot of time. The paper indicated that "if you are in Canada go to the international airport" so I did. The immigration officer there was, like: you are the second person in the last hour who shows up and wants to land but we do not do landing here". So I had to drive to the Canadian/US border the next day, about 3.5 hours. At the border it took me maybe 30 min to land. No questions asked. I consider myself luck as I think getting a PR in 9 months is pretty fast!
