Canadian Security Intelligence Service
The Canadian Security Intelligence Service (CSIS) was founded by an act of the canadian parliament, Bill C-157 , "an Act to Establish the Canadian Security Intelligence Service (CSIS)" to be a replacement for the errant and floundering Royal Canadian Mounted Police Security Service.
CSIS's mission statement is as follows: "The people of CSIS are dedicated to the protection of Canada's national security interests and the safety of Canadians". As per this statement CSIS does not have an active foreign intelligence department, but solely acts as a kind of "internal security" to protect Canada from internal and external threats. This means CSIS officers and surveillance personnel do not officially work outside the border of Canada's borders.
Some of the tasks included in this mission, known as 'Operational Programs' include:
Counter-Terrorism
Counter-Proliferation (eg. preventing the spread of weapons of mass destruction)
Counter-Intelligence
Security-Screening
Research, Analysis and Production (eg. creating strategy for the implemention the Operational Programs )
Enviromental Scanning (eg. monitering the global flow of information)
Facing Technological Challenges
CSIS has come under repeated criticism for some highly publicized failures, such as the seeming fumbling of the investigation into the 1985 Air India bombing.
