Would the War of 1812 happen without Canada?

Would the War of 1812 still happen if Canada were not part of the British Empire?

Probably, because strong anti-British assumptions in early United States foreign policy could still drive a confrontation.

The War of 1812 could still occur even if Canada were not part of the British Empire. A major current in early United States foreign policy treated Britain as the principal adversary and favored measures that opposed it. Canada supplied a convenient land objective, but it was not the only source of conflict. The counterfactual separates the war's immediate theatre from the political hostility that could still produce confrontation.
