Name one U.S. state that borders Canada.

Maine is a U.S. state that shares a border with Canada. It is located in the northeastern part of the United States and offers a long coastline along the Atlantic Ocean. The border it shares with Canada is primarily with the Canadian province of New Brunswick, and it also has a small border with Quebec. This situates Maine at a strategic point for trade and travel between the two countries.

The other states listed do not share a border with Canada. Florida, located in the southeastern United States, is bordered by the Atlantic Ocean to the east and the Gulf of Mexico to the west, with no proximity to Canada. Georgia, situated in the southeastern U.S., also does not touch Canada, and like Florida, it has coastlines along the Atlantic Ocean but is much farther south. Ohio, located in the Midwest, does share a border with Canada along Lake Erie, but it is not as direct as Maine's. The clarity of Maine's position along the U.S.-Canada border makes it an easy and direct answer to the question posed.
