I know this seems ASB, but I think that it is possible. It is true that the USA had a large advantage. The British were busy with Napoleon, Canada had about 1/10th of the American population, and the US army was much larger and fighting on its own continent. However, Britain had some advantages. They had almost complete naval superiority and Canada used to be anti-american. (it still was for some time after the annexation). In addition, the British could have potentially exploited sentiment in New England that strongly opposed the war and even contemplated secession.
In my opinion, something has to be done to cow the powerful US military before the war. The US army in the region was much larger, and nearly as well trained as the British, with good morale. They were fighting the "second war of independence" after all. Something has to be done to weaken the morale and lower the training of the US army before the war, as the British could never have a numbers advantage.
Finally, what do you think about the plausibility of a British victory and what would be the results of that victory? Would New England have seceded? What about territorial changes? The British could have taken much of the Northwest Territory, as it was sparsely settled. What is your opinion on this?
