A report from CBC News based on newly leaked secret document by former U.S. security contractor Edward Snowden reveals that Canadian spy agency was spying on the passengers who used free WiFi service in airports.
The Communications Security Establishment Canada (CSEC) is prohibited from spying on Canadians without a warrant. However, they have collected metadata about all travelers passing through Airport including Canadians.
The document presented to the CBC shows the captured information from travelers' devices was then helped the spy agency to track them for a week or more as their wireless devices connected to any other Wi-FI hot spots in locations around Canada and event at US airports.
According to CBC, the leaked document suggests that operation was a trial run of a new software developed by CSEC with the help US's National security Agency(NSA).
Two largest Canadian airports - Toronto and Vancouver - and Boingo, a largest independent WiFi services supplier at other airports, have denied the involvement in providing any information of WiFi users.
