71% without any gap is really good. You shouldnt worry. I have also applied for concordia but in Mech and Aerospace Dept, and fall intake. I would suggest you one thing. When you get acceptance letter tell them to send via express service, I guess you can use courier service to pick up the package for you from Concordia and send. May is like 3 months away, so you shall get letter soon and apply for CAQ, as CAQ also takes some time to come.
Other way is to defer admission, as concordia receives many applications, they take long time, and some people defer their application, just because they have less time for Visa and CAQ. When did you apply btw?
