Which US state has the shortest land border with Canada?
Idaho is a state in the northwestern region of the United States. It borders the state of Montana to the east and northeast, Wyoming to the east, Nevada and Utah to the south, and Washington and Oregon to the west. To the north, it shares a small portion of the Canadian border with the province of British Columbia.
It is a 45-mile land boundary with British Columbia which is the shortest land boundary between the US and Canada. The boundary is located north of Idaho’s narrow strip between Washington state and Montana. There are only two border crossing points within the boundary, Porthill which is commonly used by passenger vehicles and Eastport which is preferred by trucks.
Pennsylvania has the shortest boundary with Ontario, but it is within the confines of Lake Erie. The boundary stretches for 42 miles within Lake Erie and demarcates the lake share owned by both countries. Pennsylvania has no land boundary with Canada.
