Try looking directly on the College/University website of the place you're applying to. There can be some pretty odd/diverse ones. I know that, for example, at
Queen's there is (or at least was) a sizable scholarship awarded to the person who goes to their high school prom in a duct tape suit/dress with their date doing the same. The scholarship/bursary page of your College/University should also have more information about how they deal with financial aid for those who require it.
http://www.scholarships.com/ is also a good place to look.
Finally, many departments offer entrance bursaries; check the department website for whatever school you're applying to.
Good luck.
