Which state borders Canada?

Washington is the state that borders Canada, specifically along the northern section where it shares a boundary with the Canadian province of British Columbia. This border is notable for its proximity to major cities like Seattle and for its natural features, including the Cascade Mountains and the Puget Sound.

In contrast, Utah, located in the western United States, does not share a border with Canada; instead, its boundaries are defined by other U.S. states such as Colorado, Wyoming, and Arizona. Idaho does share a border with Canada, but it is important to recognize that Washington is often the more commonly associated state due to its larger urban centers and significant border crossings. Oregon also shares a border with the Pacific Ocean to the west, and while it has a close geographic relationship with Washington, it does not directly border Canada itself.
