Without the French winning the Napoleonic Wars it seems implausibe. The Bahamas Bermuda and Newfoundland are islands and the Royal Navy would be in the way. The most plausible outcome would be American gaining a few parts of Canada maybe just north of the Great Lakes and New Brunswick. If it relied on French support then Quebec will be back under French rule and a lot of Candians were loyalists not to mention a new influx of black loyalists who wouldn't want to be handed back to plantation owners. A redrawing of the border and maybe freer hand in what became Btritish Columbia
