Take a look at the requirements to get into Canadian medical schools (if Canada is your starting point). Evaluate yourself where you stand in relation to those criteria. Talk to admissions at the schools. Im guessing these days theres no shortage of applicants that all exceed the requirements, so you'll need to now what youll need to have a competitive chance.
If Canada doesnt work out, or America, the other option is to go to foreign country with lower standards and get a degree there. As an example:
The University of Ghana School of Medicine and Dentistry
