The land border has two sections: Canada's border with the contiguous U.S. to its south, and Canada's border with the U.S. state of Alaska to its west. The bi-national International Boundary Commission deals with issues relating to marking and maintaining the boundary, and the International Joint Commission deals with issues concerning boundary waters. The agencies currently responsible for facilitating legal passage through the international boundary are the Canada Border Services Agency (CBSA) and U.S. Customs and Border Protection (CBP).
