Following on from the earlier post on Canadian SIGINT sites past and present, here is a list of the current Canadian SIGINT sites, including links to additional information on some of the sites.

• CSE headquarters campus (map/air photo): Edward Drake Building (map/photo) + Sir Leonard Tilley Building (map/photo) + Insurance Building (map), Ottawa, Ontario
• CFS Leitrim (map/air photo/photo) and CFIOG headquarters, Ottawa, Ontario
• CFS Alert (photo), Nunavut
• CFS Leitrim Detachment Gander (photo), Gander, Newfoundland
• CFS Leitrim Detachment Masset (photo), Masset, British Columbia
• Canadian Forces Electronic Warfare Centre, Ottawa, Ontario
• Cryptologic Support Element, AIRCOM headquarters, Winnipeg, Manitoba
• Cryptologic Support Element, MARLANT headquarters, Halifax, Nova Scotia
• Cryptologic Support Element, MARPAC headquarters, Esquimalt, British Columbia
• 2 Electronic Warfare Squadron, Kingston, Ontario

Canadian personnel are also located at the following U.S. sites (and possibly some others):

• NSA headquarters (map/air photo), Fort Meade, Maryland
• Kunia Regional SIGINT Operations Center (map/air photo/photo), Schofield Barracks, Hawaii
• Medina Regional SIGINT Operations Center (map/air photo), San Antonio, Texas
• Naval Security Group Activity Whidbey Island (?) (map/air photo), Oak Harbor, Washington state
• Naval Security Group Activity San Diego (?), San Diego, California
  
• Naval Security Group Activity Norfolk (?) (map/air photo), Norfolk, Virginia
  

(The listings for Washington, California, and Virginia sites are speculative, based on the questionable assumption that the posting locations listed in DND's description of the 291 trade are accurate and up-to-date.)

Canadian personnel also are located at

• GCHQ (map/old air photo/new air photo), Cheltenham, United Kingdom

Not included on the list are the covert intercept sites reported to operate in some Canadian embassies and consulates.

Update 22 May 2006:
According to the History of Canadian Signals Intelligence and Direction Finding, there are no longer any Canadians at the San Diego and Whidbey Island sites, but there are some now at the Gordon Regional SIGINT Operations Center, Fort Gordon, Georgia.
