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.

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 as open until April 1946 [p. 466].
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"
Note 5: The Don Cameron documents, 2003-08 Part 4, on file at the National Archives Canada indicate that a DF and Comm Research facility was recommended for London Ontario by the Chief of the British "Y" mission after April 1943. His recommendations began with the building a DF station at Gloucester and a communication research/DF site in London, Ontario. Later on in the files, and closer to war;'s end, reference is made to the RCN facility in Lambeth Ont. Lambeth is a neighbourhood in the City of London so it is assumed that the names Lambeth and London are being used interchangeably.
