I was in the same exact situation since I used all of my late-drop credits at Penn State, but it never was never a factor throughout the application process/interviews. Like seeingeyeduck said, they care about your work, first and foremost.
I would choose Purchase personally. I was very close to applying to their MFA/MA program but saw somewhere that the person I wanted to study with (John Lehr) was going to be on leave in 2015. Even then, the rest of their faculty is top notch, and they seem to have a very strong concentration of artists & musicians studying there.
I guess it also depends on specifically which Canadian school you get into.
