Thank you for your question.
I have to say that state actors aren't specifically the ones that try to promote terrorist acts, including seriously violent acts. It's more radicalized individuals who live abroad or, in some instances, in Canada and who represent religious groups. They mainly promote incidents online, in chat rooms, some of which are encrypted and can't always be detected. So it isn't specifically state actors that are behind this, but rather large and small terrorist groups that like to proselytize.
