Not quite. Late in the war, the British Navy landed British troops who burned the White House.

About 85% of all Canadian militiamen remained at home when called up in 1812. In 1812 and 1813, British regulars and Indigenous warriors (from both the U.S. and Canada) invaded Michigan and Ohio, but didn't get any further than that before the U.S. counter-attacked.
