Canadian Security Intelligence Service

The Canadian Security Intelligence Service (or CSIS) was Canada's intelligence service, responsible for conducting operations against threats to national security. (Canadiology, The Toronto Files)

History
In the early 21st century, two agents from the CSIS attempted to extradite Nate from his high school transfer, but were thwarted by Evan Bertram. (Canadiology: "Serpentpedia")

When threats to Toronto became known, CSIS undercover agent Pablo was planted at Beckmore's Post-Podiums Incorporated to observe new-comer Malcom. There, it was revealed by Kosuke that Malcom had infused an Egyptian-style pedestal with a mystic trap, intended for a burial chamber. (The Toronto Files: "This Life or the Next")
