Constitutional FAQ Answer #106
Q106. "I am unaware of the status of the Articles of Confederation, but for the sake of argument, if my some outside chance Canada formally asked to become part of the union, would the United States have to honor it's commitment under Article XI? Or is the article null and void at this point in our history?"
A. Under the Articles of Confederation's Article XI, the United States made an open invitation to Canada to join the new union as a state, admission guaranteed simply by asking. If Canada had made such a request, the world would be a much different place today. The open invitation, however, expired with the replacement of the Articles with the Constitution. Canada is free to request admission into the United States, as is any independent nation, territory of the United States, or other political unit, under the rules laid out in Article 4, Section 3 of the Constitution.
