I would agree with you on that. From my perspective, going through public reports, I can count no less than eight CSIS annual reports provided to the government and Parliament that outlined foreign interference as a major concern for the agency.
In fact, the 2009-10 annual report states:
Canada has also traditionally been vulnerable to foreign interference activities. Foreign powers have engaged in covertly monitoring and intimidating various communities. In many cases, these activities are designed to support the political agendas of foreign governments, a cause linked to a “homeland conflict” or to unduly influence Government of Canada policies.
Could you perhaps point to one or two examples from the Harper era that responded to the concerns brought forward by CSIS?
