Also known as CFB Edmonton, Edmonton-Garrison or "Steel Barracks". The base was constructed by the US Army Corps of Engineers to safely accomodate vastly increasing movements at Blatchford Field (later City Centre Airport). It was taken over by the RCAF after WW2. Since about the turn of the century, only a 150 x 45m (roughly 500 x 150ft) part of runway 03/21 has been available for helicopter operations. In this view looking West, that part is at upper left, with adjacent perpendicular taxiway running straight towards the hangars with control tower.
