Didn't they burn down the capital? So there was a fight. I'm off to google some info about this.

Considering its historical significance to Canada it is surprising that so few stamps have been issued to commemorate the War of 1812. A by-product of the Napoleonic Wars that preoccupied most of Europe at the beginning of the 19th century, the War of 1812, declared by the United States on Great Britain under President James Madison on 18 June 1812, is a source of pride to Canadians as many inhabitants, principally of Upper Canada, fought alongside the Regular British Army and Indian allies to thwart American plans to capture what were then the British colonies on their northern flank.
The war was primarily caused by the British Navy's boarding of American ships to forcibly enlist any sailors of British origin and its attempts to prevent the United States from trading with France. In addition, the Americans, who were encountering strong resistance from Indians in their push westward, believed that Great Britain was encouraging Indian opposition.
The United States planned to take over Upper Canada (the basis of modern-day Ontario) and Lower Canada (the basis of modern-day Québec) in a single mass attack. The invasion was to occur at four strategic locations: across from Detroit, in the Niagara area, at Kingston, and south of Montréal. If they succeeded, they would isolate and then capture the stronghold of Québec City, thereby cutting off any further British troop movement up the St Lawrence River and into the Great Lakes.
There were wins and losses on both sides during the two years that the war lasted, with no clear victory for either of the warring parties (the Treaty of Ghent signed on 24 December 1814 maintained the status quo). The British colonies, however, remained independent of the United States and their inhabitants would continue to forge what would become some fifty years later the new Canadian nation.
Only three Canadian stamps featuring themes related to the War of 1812 have been issued: one commemorating the birth of Sir Isaac Brock, "the Hero of Upper Canada," one commemorating Laura Secord, and one in honour of Lieutenant-Colonel Charles-Michel de Saleberry. Tecumseh, who was an important ally, has never been portrayed on a Canadian stamp. He has, however, been honoured by Guernsey in a 1996 souvenir sheet that was produced for CAPEX 96.
