Movements for the United States annexation of Canada

Various individuals and movements within Canada and the United States have campaigned in favour of U.S. annexation of parts of or all of Canada or have predicted it without endorsing it since their common origin as parts of British America. Before the United States even declared its independence, there were efforts to have parts of what is now Canada join the Thirteen Colonies in their complaints against Great Britain.
