Civil liberties groups promise intel on Canadian spy agency

The B.C. Civil Liberties Association and the OpenMedia organization say they plan to make a "significant announcement" about one of the government's top spy agencies, the Communications Security Establishment Canada.

Details of the announcement have yet to be released, but the two groups have scheduled a news conference for 9 a.m. PT today in Vancouver.

The highly secretive spy agency, which is known as CSEC, reports to the minister of defence and describes itself as "Canada’s national cryptologic agency."

It supplies two main services: foreign signals intelligence, which means monitoring electronic communications emanating from abroad; and protecting domestic electronic information and communication.
