Documents obtained from whistleblower Edward Snowden reveal the joint spying effort.

Both the G8 and G20 summits were held in June 2010 in Canada’s most populated city. And both times, America’s National Security Agency conducted widespread surveillance that was “closely coordinated with the Canadian partner,” according to CBC’s account of a briefing note from the U.S. spy agency.

The multi-day spying operation focused at making sure meeting sites were safe, protecting against terrorist threats and “providing support to policymakers,” a NSA briefing document states, according to the Canadian news outlet.

The National Security Agency and the office of Director of National Intelligence, President Barack Obama’s top intelligence adviser, did not respond Thursday to CNN requests for comment on the CBC report.
