Sixty-seven years ago today, on 8 May 1938, Minister of National Defence the Hon. Ian Alistair Mackenzie approved the creation of a "Tri-Service Wireless Intelligence Service". The road that ultimately led to the Canadian Forces Information Operations Group (CFIOG) of today included a number of twists and turns: aside from the Joint Discrimination Unit, which operated from 1943 to 1946, the separate service SIGINT organizations operated largely independently of each other until the creation of the Canadian Forces Supplementary Radio System (CFSRS) in 1966. The CFSRS then became the CFIOG in 1998. But May 8th is considered to be the official birth date of the CFIOG, so Happy Birthday CFIOG!
