The majority of the community is an Indian settlement of the Fort McKay First Nation (FMFN).The smaller portion of the community, known as Fort MacKay before 2018, is located adjacent to the FMFN lands to the south within the Regional Municipality (RM) of Wood Buffalo.[4][5][6] The community was named in 1912 after Dr. Williams Morrison MacKay, the first president of the Northern Alberta Medical Association.[19] The economy is centred on the development of the Athabasca oil sands to the immediate south and north.Motorists travelling north on Highway 63 pass through oil sands developments en route to the community.
