CSEC is "Strategic Partner" of Special Collection Service
More evidence of CSEC's covert collection activities at Canadian diplomatic facilities: This slide from a March 2011 presentation on the Special Collection Service, the joint NSA-CIA organization that oversees SIGINT collection in U.S. diplomatic facilities, shows that CSEC is one of the Second Party agencies with which SCS has "Strategic Partnerships". Although not listed by name on the slide, CSEC's role is confirmed by the illustration, which includes the logos of four of the Five Eyes agencies: NSA, GCHQ, DSD (now ASD), and CSEC.
The 2011 presentation, one of the documents leaked by Edward Snowden, was published last week by Der Spiegel.
Earlier reporting by Der Spiegel confirmed that CSEC operates collection sites in unspecified Canadian diplomatic facilities and that the U.S., U.K., and Australia do likewise in their own facilities. The installations are known as STATEROOM sites by the Five Eyes.
The absence of GCSB from both documents suggests that New Zealand's agency, which is much smaller than the other Five Eyes agencies, does not operate its own embassy collection sites.
