 After finishing University, he worked on an oil rig in the Beaufort Sea.In 1997, Hooper was tasked to fly to Lima, Peru to bribe Peruvian security agents to protect the Canadian embassy, and also carried out missions in Afghanistan, Uzbekistan and Yemen during his 22-year career in CSIS.In 2007, as part of the investigation into government foreknowledge of the torture, it was revealed that Hooper had sent an earlier memo on October 10, 2002 that included the reference "I think the United States would like to get Arar to Jordan where they can have their way with him", which was the first conclusive evidence that CSIS, and not just the RCMP, knew that a Canadian was going to be tortured at the request of the United States.
