SUMMARY OF CANADIAN SIGNALS INTELLIGENCE STATIONS
Using a list originally compiled by Bill Robinson and found on BLOG: Lux Ex Umbra, this is a summary of Canadian SIGINT stations past and present. Additions and refinements to the base data are provided by Doug Stewart, Jerry Proc and references from "History of Canadian Signal Intelligence" by Lynn Wortman and George Fraser. The intent of this document is to list those stations under complete Canadian control. The table does not show Canadian SIGINT detachments who are currently deployed with U.S. Naval Security Group sites. Naval Security Group Headquarters is now the Naval Network Warfare Command Information Operations Directorate, Fort Meade, Maryland. Bill also states some dates for the World War II sites tend to be uncertain,  so further refinement is undoubtedly needed.

FOOTNOTES

Note 1: Direct SIGINT support to MARLANT  and MARPAC began during 1982 on an adhoc basis. It was in 1988 that a memorandum of understanding between concerned authorities thereby sanctioned direct support to Fleet units. This program continues and is ever expanding in its field of operations and support facilities.

Note 2: The war diary for #4 SWS indicates the station continued to have 2 or 3 on staff until 1946. The book "Scarlet to Green" also has #4 SWS listed the station as open until April 1946 [p. 466]. The book "History of Canadian Signals Intelligence and Direction Finding " by Fraser/Wortman indicates that the station was only open from April to July 1944.

Note 3: Winnipeg took over from Forrest in 1942.

Note 4: From  "A Nation’s Navy"  by Michael L. Hadley: "The first RCN built and operated station, at Harbour Grace, Newfoundland became operational in July 1941"
