Can I take sciences as elective with my undergraduate degree in Social sciences major in criminology?

Can I take sciences as elective with my undergraduate degree in Social sciences major in criminology? I have only taken grade 11 biology, and I was wondering if I would still be able to take science classes (specifically Biology, Biochemistry, organic chem, and chem) as some of my electives without having done grade 12 sciences? I am wanting to go to medical school after, and I need these courses. Is it possible that the school would have introductory courses that I could to take to lead into the actuals courses in 2nd and 3rd year?? I am going to the University of Ottawa.
