Part of the reason for that...
the parts of the USA that were nearest to Canada were also the least sympathetic to starting a war with Britain. Therefore local militia that warhawks were counting on did nothing, and official armed forces got much less support than they might have desired. Geographic issues like this mattered far less at sea.
