Which state is known for bordering Canada?

Maine is known for bordering Canada as it shares a considerable stretch of its northern border with the Canadian provinces of New Brunswick and Quebec. This geographical feature is significant, as it highlights Maine's location in the northeastern United States, making it an essential part of the region where the U.S. meets Canada.

Other states mentioned do not share a direct border with Canada. Texas is located in the southern part of the U.S., Arizona is in the southwest, and California, while it has extensive coastlines along the Pacific Ocean, is located further south and does not extend to the Canadian border. This distinction allows Maine to be correctly identified as the state that borders Canada.
