The Canada Border Services Agency says the Chief Mountain port of entry will be open for the summer season on May 15 through Sept. 30.
The international border crossing is located along Highway 6 in Alberta on the boundary of Waterton Lakes National Park in southern Alberta and Glacier National Park in Montana.
The Chief Mountain international border crossing has the highest elevation of any border crossing in Canada and is also one of the most scenic.

With an elevation of more than 1,700 metres (5,649 feet), it is the highest of all border crossings in Canada and is considered one of the country’s most scenic ports of entry.
Due to harsh winters and its elevation, it only operates for the summer season.
