The CSIS Public Report discusses Canada’s security environment and CSIS’s national security role. It has been recognized that increased public knowledge about the defensive, domestic nature of CSIS’s mandate will help Canadians understand how the national security of Canada is safeguarded by the Service, with due respect for individual rights and freedoms. The Report also improves the understanding of the purposes and processes of the Service and addresses many of the popular myths surrounding security intelligence work.. The Report is available from the last fiscal year to 1991.
