The Canadian military felt snubbed by the RCMP and CSIS after the civilian security agencies began investigating navy spy Jeffrey Paul Delisle without telling them, according to secret documents obtained by CBC News. The documents paint a picture of a shattered military security system, scrambling to catch up with an outside investigation into one of its own, former Sub.-Lt. Delisle, one of Canada’s most prolific spies.

The military’s fears were well-founded, given Delisle had access to terabytes of some of the Western world’s most closely guarded secrets. He operated a computer system called Stone Ghost, which links the intelligence services of the Five Eyes: the United States, Britain, Canada, Australia and New Zealand.
As a threat assessment officer for the Canadian navy, Delisle was responsible for drafting daily reports on anything a Canadian warship operating on foreign waters might encounter. That gave him access to everything from weather reports to the movement of terrorist cells and organized crime gangs.
Delisle used an external disk to transfer gigabytes of secret information from the Stone Ghost computer to a non-classified computer. He would then transfer the information to a thumb drive. Once a month, he emailed the sensitive Five Eyes information to his Russian handlers.
