CBC News – A top secret document retrieved by U.S. whistleblower Edward Snowdenand obtained by CBC News shows that Canada’s electronic spy agency used information from the free internet service at a major Canadian airport to track the wireless devices of thousands of ordinary airline passengers for days after they left the terminal.
After reviewing the document, one of Canada’s foremost authorities on cyber-security says the clandestine operation by the Communications Security Establishment Canada ( CSEC) was almost certainly illegal.
