Disadvantages of applying to US med schools as a Canadian?

What I do know (at least what I think I know) so far:

• Limited choices for schools because many only take US residents
• Financial aid pretty much out of the question
• Canadians are viewed favorably over other International applicants

That being said,

• Are Canadian applicants placed in a separate pool?
• Considering I get good enough stats for a certain school, are those numbers given an asterisk, or would I be held to the same standard as domestic applicants?...
