OTTAWA — Leaked documents suggest Canada helped the United States and Britain spy on participants at the London G20 summit four years ago.
Britain’s Guardian newspaper says spies monitored the computers and intercepted the phone calls of foreign politicians and officials at two G20 meetings in London in 2009.
The paper says the effort included penetration of delegates’ BlackBerry smartphones to monitor their email messages and calls.
The Guardian published PowerPoint slides describing the operation, including one featuring the emblem of the Communications Security Establishment, Canada’s electronic eavesdropping agency.
It appears alongside the logos of key allies — the U.S. National Security agency and Britain’s Government Communications Headquarters — along with an icon labelled Joint Apps.
The documents were leaked to the Guardian by former NSA contractor Edward Snowden.
