User is German, asking on a Canadian instance, and on post about a Canadian news. I'd say that's pretty reasonable. Canadian is part of America, as well as the USA.
It also refers to the combined area of North and South America. This the more likely usage here, as who would ask about whether or not the USA has such regulation in a Canadian forum? That would have no relevance.
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.
The concept of ‘America’ these days does not apply to continental plates
The thing is, we keep a record of how words are commonly used, and that record tells that it absolutely does refer to a set of continents. But, I know, let's not let facts and figures get in the way of random internet nonsense.
You know what I meant
Yes, I know you meant it in jest. Nobody would actually take time out of their day to write such a comment earnestly. We can all see that.
