Wanting, and actually getting in are two completely different things. I have to agree with @lookingforward and @parentologist, it is a holistic process. Spending upwards of over $300k for undergrad, for something that is not guaranteed, seems pointless when you have stellar options in Canada. (You won’t qualify for massive loans for medical school if you’re not a US citizen.)
It doesn’t matter if you go to the US for undergrad. There are some spots in medical school that have Canadian students, but the percentage is very, very small.
Also, making excuses that your school is underfunded to take you on a few math club trips, isn’t helpful. This is an issue that faces thousands of high schools in the US. What those schools do is they funraise. Since money no object to you, I’m surprised that your parents haven’t stepped in to help with the funding of these types of extracurriculars. That’s what parents do in the US; they’re the first point of donations.
As an international candidate and “over represented minority” (ORM) it will be very rough to get into any medical schools because it is a very competitive process and most of those spots are reserved for US citizens.
Agree that it seems all or none. Are you and your family trying to get you to immigrate into the US? I see no other reason when your options in Canada are so much better. @WayOutWestMom can give you more information on your chances.
