"CSIS’ mandate is to act as a domestic intelligence service, surveying domestic threats and running counter-intelligence. While it has long tried to run operations abroad, Canadian courts have repeatedly stood in its way, including attempts to cooperate with the NSA to intercept communications in other countries.
Under this new legislation, CSIS would be unique amongst the so-called Five Eyes – the intelligence partnership of Canada, the US, Britain, New Zealand, and Australia – by being the only agency in the group to be empowered with domestic and foreign spying powers. In the US, a coalition of Homeland Security and the FBI manage domestic security and anti-terrorism programs, while the CIA manages foreign intelligence.
