Canadian SIGINT sites past and present 3.1

Here's another update of my list of the main Canadian SIGINT operating sites past and present and their years of operation (previous version here). The major change is the addition of the RCN HFDF site that operated in Lambeth, Ontario from 1943 until ca. 1945. Thanks to Jerry Proc for tipping me off to its existence and to the Westminster Historical Society for providing further information about the station! As noted on earlier versions, available information on the Second World War sites still tends to be somewhat spotty, so a lot of the dates associated with those remain uncertain. Also, my guesswork still differs in a few places from the estimates made by Jerry and others (and maybe all of us are wrong on some dates), so further refinement is undoubtedly needed.

The list does not include the various operating sites of the Special Wireless Sections Type “A” and Type “B” in Britain, Italy, and North-West Europe from 1941 to 1945 or similar operations that may have taken place in the years since the Second World War when Canadian forces have been operationally deployed. Also not included are the covert intercept sites reported to operate in some Canadian embassies and consulates.

In addition to the personnel posted to the Canadian Special Liaison Offices (CANSLO) at NSA and GCHQ, a number of CSE personnel are posted to exchange positions inside the agencies of Canada's UKUSA partners. Canadian military personnel are also posted to a number of U.S. sites under the CF-USN Personnel Exchange Program (PEP). The History of Canadian Signals Intelligence and Direction Finding (p. 18) listed the following PEP locations as of 2005: Naval Security Group Headquarters (now the Naval Network Warfare Command Information Operations Directorate, Fort Meade, Maryland); NSGA Norfolk (now Naval Information Operations Command Norfolk), Virginia; Kunia RSOC, Hawaii; and Gordon RSOC, Georgia. The Gordon RSOC is also listed as the location of a CFIOG detachment (p. 133); these listings may refer to the same personnel. In the list above "det" is used to refer both to detachment locations and to sites where exchange personnel have been posted. Sites reported in 2009 are listed here. At various times, Canadians have also been posted to other U.S. sites under the PEP program, including Homestead, FL; Skaggs Island, CA; Imperial Beach, CA; and Wahiawa, HI. There was also at one point during the Cold War a personnel exchange program with the British Army that saw Canadian personnel serving with the 13th Signal Regiment at Birgelen, West Germany.
