Canada never really "joined" the British Empire. Rather the reverse, the British Empire acquired Canada in pieces, with no volition on the part of Canadians, either the original native inhabitants, or the contingent of New France settlers in the 18th century, whom the British conquered and occupied.

The difference being that the United States separated from the Empire, in a revolution, whereas Canada more or less evolved as a distinct and sovereign country. And even the Empire evolved, world wide, into the Commonwealth of Nations, sharing the monarch, but really nothing else.
