It's unlikely the War would have gone on for 3 or 4 more years. The Brits had no particular war aims and their military policy was simply to raid and burn, preferably shipyards. They had a far more important war to deal with.
The Americans had to ask for peace, in OTL the US government was bankrupt.
By the way, yankee war aims were to stop the Royal Navy searching their ships and pressing American sailors. Officially they didn't achieve these, although unofficially it happened. As I understand it, Canada wasn't official. There has always been a sector of US public life that thinks the Canadians want to be part of the US. When the militia marched, Washington had to go along with it.
Rather than carry on a war when you can't pay any more troops, the end effect might have been that the US put all or part of the Louisiana Purchase on the market. I can't see the British would have interfered: As I said they had a more important war, but perhaps even more significant, there has always been great deal of sympathy for the "cousins" in the UK - at least until the 1950s
