Butthurt guy whines about Canada's warship names

[Malthus]

There is also this: Quebec aside, the Canadian colonials were simply not very different from the Americans, right up to the War of 1812. There was a population of United Empire Loyalists it is true (who had fled the US on losing the Revolution), but the majority of colonists were not; many in Upper Canada were in fact American-born, not UELs, who had moved to Upper Canada pursuing economic interests. In any event, the ethnic make-up of English-speaking Canadian colonists was more or less identical to those in the US.

Indeed, at the beginning of the War of 1812, there was a widespread expectation in the US (and fear on the bart of the British authorities) that the colonists would support the invaders.

What changed all that was the war itself, particularly in Niagara, which was one of the hotspots. In particular, mutual perception of atrocities (the Brits supporting the Indians was a big US grievance) led to an escalating cycle of abuses aimed at the general population - the US burning and pillaging of Newark and York, for example, which led to retaliation burnings and pillagings across the border in revenge, the most famous of which being Washington itself. This had the effect, as it often has done in other places, of heightening or creating differences and nationalistic feeling, even when none had previously existed. [Note that the burning of Newark was alleged to be the fault of "Canadian" volunteers serving with the US forces]. 

The War was very significant in creating this feeling of incipient nationalism. It did not lead to nation-formation at that time exactly because it was not aimed at the Brits: Canadians felt their interests were best served by inclusion within the powerful British Empire.
