History.
The airline was established in 1966 as Vic Turner Ltd which operated a single de Havilland Canada DHC-6 Twin Otter providing air support for oil exploration activities in the Canadian Arctic. Renamed Kenn Borek Air after being purchased by Borek Construction in 1971, the company acquired the Aklavik Flying Services which was founded in April 1947 by Michael Zubko operating a single Aeronca Champion at that time. In 1975 Kenn Borek acquired Kenting Atlas Aviation which was established in 1947 as Atlas Aviation then renamed to Kenting Aviation in 1972.
The company has been operating in Antarctica since 1985.
On 26 April 2001, Kenn Borek Air used a DHC-6 Twin Otter aircraft to rescue Dr. Ronald Shemenski from the Amundsen–Scott South Pole Station. This was the first ever rescue from the South Pole during polar winter. To achieve the range necessary for this flight, the Twin Otter was equipped with a special ferry tank.
In 2009, the company was commissioned to recover a crashed aircraft in the Antarctic, and employees spent 25 days in a makeshift camp to complete the project.
The airline was used by the BBC during the filming of the documentary "Frozen Planet" (2011), which was narrated by David Attenborough, and one of its planes is seen in portions of the footage.
In June 2016 the company assisted in removing two sick workers from Antarctica during the polar winter. Two Twin Otter aircraft were used and successfully completed the mission. The crew, 
Capt. Wally Dobchuk, first officer Sebastian Trudel and maintenance engineer Michael McCrae were honoured for their heroism by Aviation Week.
Operations.
Kenn Borek Air offers a full service overhaul maintenance hangar in Calgary with routine maintenance being completed wherever the aircraft is located.
