CSIS did not observe any violent extremist plots targeting the Muslim community last year, while multiple plots against Jewish people were foiled.

The Canadian Security and Intelligence Service (CSIS) says various evolving forms of violent extremism are becoming increasingly difficult to address and even understand, with secret and anonymous online radicalization challenging investigators’ ability to keep pace.

The agency’s annual report released Friday said violent extremism “continues to pose a significant threat to Canada’s national security and remains a critical operational priority for CSIS,” noting such extremism is “motivated by an increasingly diverse range of beliefs and convictions.”
