Subsequently in 1963, the whole Canadian radar network was divided into regions and incorporated into the SAGE network. SAGE did away with manual plotting and controlling. The radar inputs came into the region headquarters from all the CADIN/Pinetree Line sites. The system was now computer based and the whole of the region could now be observed and controlled from one location. This resulted in the radar sites reducing their Operations personnel by about a half to 200 personnel and less. The sites consisted of an operations and domestic section. The operations site, always located on the highest point in the vicinity, had a main building with a search and two height finder radars. The antennas were enclosed in radomes to protect them against wind damage. There were two types of radomes, the rigid fibreglass geodesic dome and the blower constant pressure inflated rubber dome.
