Canada is within America. America is exceedingly broad, with so many different jurisdictions, all with their own rules. There is no single answer as to what the rules are across all of America. Since this is a Canadian forum, Canada was a reasonable choice to narrow down to.
There is still room for you to dive into some of those other jurisdictions, if you find it pertinent, but I expect nobody here actually cares about what is going on in, say, Mexico.
