Getting a second degree?

[blackni]

Hi,

I'm studying in a top20 school in the states now but would like to come to Canada to enjoy the life and study CS. I major in Math and Political science, and probably minor in history. Will it be a good idea to get another Bachelor degree in Canada, or I should just do another major in CS (I can get a BA in CS, but not BS because I need to do Math and Polici at the same time. If I'm doing a CS major, I would not be able to take any history classes and I'm quite upset about this) and apply to a master program? Will having a BA hurt my chance of getting to a good master program?

I know UBC has a 2-year BCS program. This suits me a lot because I don't really want to spend another 4 years in college. Do any other schools have similar programs?

Thanks!
