My status changed from review in progress to recommended for assessment this afternoon too!
I too had some difficulty with GSPIA, but it just seems like they are very slow to update Infoweb. Despite what Infoweb said, there actually ended up being no problem with my application.
I don't know very much about Munk, but I know a little bit about BSIA. I didn't apply because I am interested in the public service and I would like a change from Waterloo after doing my undergrad here, but I have had many classes with profs affiliated with Balsillie/CIGI and I have gone to events and panels put on by CIGI. The campus is beautiful and the faculty are great. I know a few people who are currently attending and they all seem more than happy. Waterloo is not the most exciting city, but at least it is pretty cheap there! If you are considering it, you should definitely find the time to visit.
