I worked it out with friends, and the funding actually isn't that different when calculated by semester. I really want to work for the federal government after. So I'm definitely choosing NPSIA then! Thanks for the help and advice!
@Tyxce From what I hear, Balsillie offers a great education. It's a very well-funded program. That being said, as to whether or not it beats out NPSIA (in your case) depends on your vocational goals. If you aim to work for the feds after graduating, I don't think NPSIA can be beaten; the location alone would suggest that. If you're more interested in NGO work, I don't think it matters AS much where you go to school, just that you develop tangible skills and a network. Personally, I'd go with whatever lessened my debt burden the most drastically.
But maybe I'm just cheap
