The 49th parallel of north latitude forms part of the United States-Canadian Border from Manitoba to British Columbia on the Canadian side and from Minnesota to Washington on the U.S. side, or from the Lake of the Woods to the Strait of Georgia. Its use as the international border is a result of the Anglo-American Convention of 1818 and the Oregon Treaty of 1846.
