Canadian SIGINT sites past and present

Here’s a list I’m working on of the main Canadian SIGINT operating sites past and present and their years of operation. The information that I’ve seen on the Second World War sites tends to be spotty, so a lot of the dates associated with those are guesses. I hope to get better information on those and other stations as time goes by. Any suggestions readers can make for additions, corrections, etc would be gratefully received!

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.

Canadians are also posted to a number of U.S. sites under the CF-USN Personnel Exchange Program. Currently, these sites include Fort Meade, MD; Kunia RSOC, HI; Medina RSOC, TX; and possibly San Diego, CA; Norfolk, VA; and Whidbey Island, WA. At various times, Canadians have also been posted to other U.S. sites under this program, including Northwest, VA; Homestead, FL; Skaggs Island, CA; Imperial Beach, CA; Wahiawa, HI; and Naval Security Group Headquarters (Washington, DC).
