According to the website of the Canadian Security Intelligence Service (CSIS), under the section “National Security Threats – Terrorism”:
“Terrorism, including terrorist travel and the radicalization of Canadians, is the most prominent threat to Canadian interests and our national security. The intelligence community has never before faced a terrorist threat of this scope, scale, and complexity.”
The CSIS text, last modified on January 27, 2017, also notes that, despite ISIS’s huge losses, “its ideology continues to hold global appeal, including among susceptible Canadians,” and Canadians with extremist Muslim views “continue to engage in a range of terrorist activity, in Canada and abroad.”
By January 2017, CSIS was aware of:
“approximately 180 individuals with a nexus to Canada who are engaged in terrorist activity abroad, approximately half believed to be in Syria or Iraq.
“The activities of these extremist travellers vary widely, ranging from planning operations, training, and logistical support, to fundraising and studying at extremist institutions.”
The number of “people suspected of travelling overseas to engage in terrorist activity” increased to about 250 by November 2017, according to Public Safety Minister Ralph Goodale.
