The British couldn't be bothered taking any US territory since the War of Independence had proved that the US was ungovernable. Besides it was a small deal to them, at least compared to what was going on in France at the time.
But on a military level it was a very sound defeat. The US couldn't make headway in 2 years against much smaller numbers. And once British troops were free to really response, the only thing that the US had which resembled a victory happened after they sued for peace.
Cheers,
