The latest Snowden leak was an exclusive to Canadian Broadcasting:

"The briefing notes, stamped "Top Secret," show the U.S. turned its Ottawa embassy into a security command post during a six-day spying operation by the National Security Agency while U.S. President Barack Obama and 25 other foreign heads of government were on Canadian soil in June of 2010...
An NSA briefing note describes the American agency's operational plans at the Toronto summit meeting and notes they were "closely co-ordinated with the Canadian partner."
