I'm hoping its different for each person. The guy told me it should be no more than 20 days for mine. I'm also going to Concordia for a MA. I'm from the states so I am able to apply for the Visa at the Canadian port, so the CAQ is my last thing to wait for. Good luck with everything!Ohh!! Congratulations!!
Keeping your time frame in mind the wait is for 40 days.
Can I ask as to which universities you guys have all applied to? Can be of further help going ahead with the Visa applications.
FYI, I myself got accepted into Concordia University for the MBA program.
