Article content OTTAWA — Canada’s digital spy agency responded to more than 2,000 attacks on the federal government and its critical infrastructure partners last year, according to a new report, amid heightened concerns over the use of cyber warfare tactics by foreign actors. In its annual report, the Communications Security Establishment (CSE) said it provided assistance to the Government of Canada or its critical infrastructure partners 2,206 times, including 84 incidents “affecting Canada’s health sector.” It is the latest in a number of recent reports detailing the higher frequency of cyberattacks being directed toward Canada, including a recent report by the Canadian Security Intelligence Service (CSIS) that found “espionage and foreign interference activity at levels not seen since the Cold War,” mostly carried out by Chinese and Russian-backed actors.
