File:East Coast Radar Coverage WWII.jpg

Planning for radar stations on the East Coast of Canada had started in 1940. Siting had been completed, equipment ordered and on site construction completed to enable the first stations to become active by mid 1942. The last of the stations would become operational in late 1944. The role of these stations varied depending upon the equipment at each location. They included chain home low - early warning radar (CHL), microwave early warning radar (MEW), ground controlled intercept radar (GCI) and high-fying early warning radar (TRU).
