Name one state that borders Canada?

Washington is a state that borders Canada, specifically along its northern edge. This geographic location allows for a direct boundary with Canada, including cities like Seattle that are close to the border. Washington is part of the Pacific Northwest region and has significant interaction with Canada, including trade, travel, and cultural exchange.

Oregon also borders Canada, but it is primarily through the Columbia River and is less direct compared to Washington. Nevada does not share a border with Canada at all, as it is located further south, and Montana, while it does have a border with Canada, is not the specified correct answer in this instance. Thus, Washington accurately represents a state with a clear and substantial border with Canada.
