Internship Opportunities in Toronto?

First off, I'm a second year mathematics (and a little physics) student with a 3.5 GPA at a fairly reputable school in Canada and I'm looking to see what doing this business thing is like so I can make a decision about whether I want to aim for this or not. Does anyone know of any internship opportunities around Toronto? I'm staying there over the summer so it would be a nice location, though I'm willing to take a job in Vancouver as well. Problem is, the management consulting firms typically only take 3rd years, and the Canadian banks/firms only seem to like economics/business students (from what they say they're looking for at my school's Career Centre listings). Anyone know of any other firms in Toronto willing to take someone with a random background like mine? Thanks.
