A memo said CSIS's internal security investigated leaks of classified spy agency information and documents that led to a series of media articles beginning in November 2022

OTTAWA — Canada’s spy service tracked the flow of its intelligence reports across government and studied how other agencies handled them as part of an investigation into leaks of classified information about foreign interference, a newly released memo shows.

The Canadian Security Intelligence Service described the “tireless efforts” in the memo prepared for staff who were keen for an update on the probe into unauthorized disclosures to the media.
