The Pentecostal Sub-Arctic Mission received its start in 1949 when Rev. Ken Gaetz pioneered a mission work in Hay River. The construction of the Hay River Pentecostal Chapel in 1950 was the first Pentecostal church to be started in the Northwest Territories. The work began to take hold as Pastor Gaetz labored and in 1952 he was ready to help establish a mission outpost in Fort Resolution. In 1953 a small nursing station was established in Hay River, the first such medical service offered by the Sub-Arctic Mission. A mission outpost was started in Fort Simpson in 1956 at the same time a Dene mission was started in Hay River.
The financial structure of the mission came into effect in 1957 when the first hospital was opened having six active treatment beds. The hospital proved to be too small and in 1959 it was expanded to twelve beds. Fort Norman came on stream in 1959 and in 1962 a mission station was established in Fort Good Hope. The town of Hay River relocated as a flood devastated Vale Island in 1963. With the relocation of the town a new twenty-two bed hospital was built there in 1965.
The first Inuit mission was started in Coppermine in 1967. This work is located on Coronation Gulf which joins to the Arctic Ocean. 1968 marked the pioneering of a work in Fort Providence. Fort Smith started a mission work in 1972, and Pine Point joined the mission work in 1974.
Again the hospital was proving to be too small. Thus a modern fifty bed hospital was opened. The government of the Territories entered into a long term agreement with the Pentecostal Sub-Arctic Mission to operate this new facility. This necessitated the Pentecostal Sub-Arctic Mission becoming chartered under the Societies Act of the Northwest Territories. After thirty-two years of ministering in the North, Rev. Ken Gaetz resigned as Executive Director of the Mission. While he pioneered the work in Hay River he established other works in the North and set up the Pentecostal Sub-Arctic Mission.
The work of the Mission is still ongoing. In 1983 a mission office was built by adding on to the existing medical clinic. A full fledged Bible College was started in Fort Smith in 1985. The Sub-Arctic Leadership Training (S.A.L.T) provides training for those desiring to minister in Canada's North. The vision of the mission is ongoing as we seek to spread the gospel to all the North.
