Bad Decision: Need Advice

Hi guys:

I'm a recent University of Toronto graduate with a degree in poli sci and minor in organic chemistry. I "followed my interest" in my undergrad, thinking that once i graduate I can apply for a variety of jobs. However, this seems to be an exclusively American target school privilege. Now I'm really interested in investment banking, but because I didn't major in finance, there is no way I can get a gig in Canadian IB (also, my GPA is a bit rough). What would you suggest in my position? My GPA is 3.2, I was head of a frat, and I've had two summer industrial chemistry internships. I'd appreciate any advice? How can I leverage my background to get relevant finance experience now. Not IB, but something that I can leverage into IB later on

Btw, I know that I can do an MBA later, but without previous experience in the industry, my chanced of landing associate gig seem low.
