Chief Mountain port of entry in Alberta closes for the season

CALGARY, AB, Sept. 23, 2026 /CNW/ -- The Chief Mountain port of entry at the Canada-United States land border between Alberta and Montana is closing for the season on Wednesday, September 30 at 6:00 p.m. Mountain Daylight Time (MDT). It will reopen in the spring of 2027.

Due to its high elevation and harsh winters, the Chief Mountain port of entry only operates from May to September, annually.

During the winter closure, travellers can use the Carway port of entry, Del Bonita port of entry or Coutts port of entry as an alternative.

Chief Mountain is located south of Calgary along Alberta's Highway 6 on the boundary of Waterton Lakes National Park. At 1,722 meters, 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.
