Let’s start with 1812. I know a few folks think Americans defended themselves when in fact it was American warhawks high on their revolution win, that went on the offensive.

More recently, WWI, WWII, Korean, Vietnam, Cold War, Afghan etc, we’ve been allies and very good ones at that.

American-Canadian Wars

1. The War of the League of Augsburg (King William's War) 1689-1697

2. The War of the Spanish Succession (Queen Anne's War) 1701-1714

3. The War of the Austrian Succession (King George's War) 1740-1748

4. The Third Silesian War (The French & Indian War) 1754-1763

5. The War of the American Revolution 1775-1783

6. The War of 1812 1812-1815

Of course, in four of those wars, we were English and Canada was French, and in the last two, Canada was still English. There have been no wars between an independent Canada and the US.
