TORONTO (AP) -- A secret document leaked by U.S. whistleblower Edward Snowden shows Canada's electronic spy agency used information gleaned from a free internet service at a Canadian airport to track the wireless devices of thousands of airline passengers.
The Canadian Broadcast Corporation said Friday that the report indicates the Communications Security Establishment Canada was given information taken from wireless devices using the airport's Wi-Fi system over a two-week period.
It's not clear which airport was involved.
The spy agency is supposed to collect primarily foreign intelligence by intercepting overseas phone and internet traffic. It is prohibited by law from targeting Canadians without a judicial warrant.
The agency's spokeswoman Lauri Sullivan says no Canadian or foreign travelers were tracked or targeted and no information was collected or used.
