What courses should I take in high school to prepare myself for Med. school?

I have to pick my Gr. 11 courses, for next year, next week. I know Im going into med schooI, and Gr. 11 is the year that counts the most. I just wanted to run my course selections by someone who has been through the system to see if Im on the right track:

Chemistry

Advanced Placement Biology

Physics

Gr. 11 Math

Advanced Gr. 11 Math (Second Semester)

English

Canadian Law

Child studies

Also if anyone is familiar with how the medical school system works in Canada and could explain it in a way that is easy to understand. Everywhere I look, I read something different and more confusing. Im just wondering what I need to take as a pre-med student before applying to med school, then how the Majoring and Minoring works from then on throughout the system. Also if anyone knows what the most helpful course is to major in, I would love some input. Im drifting towards specializing in pediatrics waaay way way in the future, so if anyone has any info, I would seriously appreciate it. Anyways, thanks so much in advance!
