CALGARY, AB, May 7, 2026 /CNW/ - The Canada Border Services Agency (CBSA) is advising travellers that the Chief Mountain port of entry will be open for the summer season from Friday, May 15, 2026, to Wednesday, September 30, 2026.

Chief Mountain is located along Highway 6 in Alberta on the boundary of Waterton Lakes National Park in Alberta and Glacier National Park in Montana. At 5,649 feet, it has the highest elevation of all border crossings in Canada and has long been considered one of Canada's most scenic ports of entry.

The Chief Mountain port of entry only operates seasonally from May to September due to its high elevation and harsh winters. During the 2025 summer season, the CBSA welcomed over 56,000 travellers at the Chief Mountain port of entry.

Chief Mountain hours of operation (Mountain Daylight Time):

May 15, 2026 – May 31, 2026: 9:00 a.m. to 6:00 p.m.
June 1, 2026 – September 7, 2026: 7:00 a.m. to 10:00 p.m.
September 8, 2026 – September 30, 2026: 9:00 a.m. to 6:00 p.m.
