Hmmm, looks like I guessed your interest! Okay, so PLEASE consider what I’m about to say. Do your undergrad and med school in Canada. You qualify as a permanent resident there to go to any school there, at resident rates. If you can get into McGill, go there. Otherwise, go to the best school you can get into in Canada. Then go to the best medical school you can get into in Canada. You’re looking at under 100K total for undergrad and med school, maybe under 50K, depending upon your provincial residency, vs as much as 750K total for undergrad and med school in the US.
Unless you come from some incredible family wealth, and are an only child, there is no argument you can make that outweighs possibly 700K difference in the cost of your education. There are many brilliant US students who would KILL for the chance to go to McGill undergrad and McGill med at Canadian resident rates.
It’s not a bad thing to finish in 3 years, if you don’t have college level education available to you at your high school. But overall, admin committees in the US are going to think, “Hmmm. 16. Is this kid ready for college? Why is he leaving high school early?” Whereas from what you say it’s no big deal in Canada. In the US, no one thinks, “Oh, he’s SO smart that he finished high school in 3 yrs!” They think, “Does this kid have a social problem that he’s escaping - family troubles? Outcast in high school?”
At the very least, make reach, match, and safety options for yourself in Canada, and then for the heck of it, if you want to, throw in a few applications in the US at schools you might want to go to, which might give you substantial merit aid (unless you are incredibly wealthy and don’t need to consider money).
Your backstory is interesting. Your extracurriculars are interesting, but achievement at the middle school level is not what they’re looking for, and not in archery. There is nothing in your application that helps an admissions committee to rank you against your peers academically. Small rural Canadian school, and you’re not first in your class, or top 3 there. No standardized test scores. No competitive exam achievements.
I have a feeling that an admissions committee would see you as an academic mystery. Top schools would pass on you, and less competitive schools that award merit money might admit you, but not award merit money.
If you are absolutely one thousand percent determined to go to the US for college, I would say you should prep hard for the SAT or ACT, get a stellar score, and apply next year. Meawhile, take online high-level classes through something like the Center for Talented Youth at Johns Hopkins, or via online classes at the most highly respected, known Canadian college you can get them at, or self-study for some AP classes and get 5’s on them this spring, so that you can give an admin committee for next year some hard data points so that they can assess you academically.
