Brazilian President Dilma Rousseff is demanding an explanation from Canada after reports a Canadian intelligence agency spied on Brazil’s mining and energy sector. A Brazilian TV report based on leaks from Edward Snowden given to Brazil-based journalist Glenn Greenwald said Canada targeted the communications of the former Brazilian ambassador to Canada as well as those of staff at the ministry managing Brazil’s vast energy reserves. In a Twitter post, Rousseff said, “The United States and its allies must immediately stop their spying activity once and for all.”
