Paying for school in Canada (a US citizen)?

I was accepted at University of Waterloo for the Mathematics, Honours program for fall 2011 as a transfer student (I assume to the second year of my program, but I'm not sure yet of how my credits transferred) a week ago (I applied about a month and a half ago), and I am at a loss as to how I'm going to pay for it. I can't seem to find a loan that will allow me (a US citizen) to pay tuition at a Canadian school. I plan to defer until at least the winter term and work full-time until then to pay for an apartment, but I need to find a loan for the tuition itself. Does anyone know of any banks or anything that will loan to a US citizen to study in Canada for an undergraduate degree? Thank you!
