Current York undergrad: I also received an offer from York mid-Feb. (but turned it down for another offer). Their funding for the M.A. level minimally covers tuition + fees, and a little change left over. This obviously also depends on whether your asking about the M.A. or doctoral and for which program, and if your domestic or international. The Philosophy department at York recently received a very generous donation which has resulted in relatively competitive funding offers, compared to the other departments (my brother is currently doing his PhD in Phil. at York). So, certainly a school to consider if you get an offer from there (assuming you haven't heard already).
Good Luck!
