The French and Indian War (1754–1763)

King George's War (1740–1748)

The British and French colonial empires contested Canada through several wars:

The United States invaded Canada in two wars:

The American Revolutionary War - see Invasion of Canada (1775)

The War of 1812 - see Invasion of Canada (1812)

A small group of American rebels from the Hunters' Lodges invaded Canada in the Patriot War (1837-1838) and the Battle of the Windmill in 1838.

The Fenian raids, based in the United States, also targeted Canada between 1866 and 1871.

The United States developed an invasion plan known as War Plan Red in the mid-1920s. The plan was a contingency for the unlikely event of war with the United Kingdom. It was officially withdrawn in 1939.

The Invasion of Canada is also a 1980 book by Pierre Berton about the War of 1812.
