CBC News has published documents related to a story showing how the United States and Canada worked together to eavesdrop during the G8 and G20 in Toronto in 2010.

CBC News believes in transparency and showing supporting documents to its journalism. It held back on publishing the U.S. material until discussions with the U.S. government had been completed over the weekend.

The material is sensitive and CBC News has removed, at the request of the White House and the U.S. Director of National Intelligence, information that may identify individuals who could be at risk if the material was released.
