What privileges are authorized in the US to persons holding an amateur service license granted by the government of Canada?

The United States and Canada share a special reciprocal operating agreement. When a Canadian amateur operates in the US, they are automatically granted the privileges associated with their Canadian license class. However, these privileges cannot exceed the maximum privileges allowed under US regulations, which are those of the Amateur Extra class license. This means the visiting operator must follow the rules of both their home country and the host country, taking the more restrictive of the two. They do not need to apply for a separate US license, nor are they arbitrarily restricted to just a few HF bands, making the other options incorrect.
