CFB Edmonton – Wikipedia

With time, RCAF Station Edmonton also developed severe limitations at Blatchford, and on 1 October 1955 all RCAF Squadrons and support units were transferred to the “new” RCAF Station Namao. Blatchford Field was turned over to the Edmonton municipal government and became the commercial Edmonton City Centre (Blatchford Field) Airport .
