Congratulations ^^ ! and i wish you your first choice
My third choice is International Studies at Laval University, which is in french. The structure of the program is about the same as NPSIA, but I would prefer Carleton, better reputation, it's in Ottawa and it's in english.
My second choice is Political Sciences MA at Mcgill, mainly for the reputation of the school, but it isn't really a professional MA. The good point in Mcgill is that it's in Montreal, but still then, I will be extremely sad not to get into NPSIA lol
Did you apply at a lot of programs ?
