Can Canadian students apply for USA medical schools?

I am a Canadian university student and trying to apply for medical schools in USA. Is it possible for me if I have not learned any university courses in US before?

I assume that you are a citizen of Nepal. US medical schools have an extremely limited number of spaces for international students. Competition for these spots is intense, more so than for US students. Also there would be little or no funding.

The same would apply if you are a Nepalese who did their undergrad in he US.
