The Canadian Security Intelligence Service (also known as CSIS) is a Tau'ri organization from Canada. Dr. Rodney McKay described it as the Canadian version of the Central Intelligence Agency. In 2007, CSIS liaised with the National Intelligence Department after McKay's sister, Jeannie Miller, was kidnapped. (SGA: "Miller's Crossing")
