Its because VAC is closed and they cannot ask for a passport request for printing. Even in the second stage they will simply not refuse your Visa, they will ask for further documents etc. Be grateful that Canada is doing so much incoming students. Unlike the US who was planning to kick out students who are already there.I don't understand .... if people (like the person who got their visa in this thread) have submitted complete applications, why on earth would they bother with this AIP stuff and not issue them the final approval? It's not like any more documents are required as the biometrics and medical are done.
