Check your geography. Windsor is actually south of Detroit.
and clear the way for the capture of Ottowa by a company of Second Amendment Sisters.
Ottawa is four or five hundred miles from Windsor/Detroit. Much easier to just go the 60 miles north up highway 16 from the bridge over the St. Lawrence at Prescott.
(BTW, the last time the US tried to invade Canada got Washington DC burned, although Canada had British support then. Don't know that they would this time.)
