The short answer is yes.
Without going into too much detail due to the sensitivity, I have had, for example, in-person surveillance conducted. I am a regular recipient of death threats. I have had regular cyber and malware hacking attempts directed from the regime in Iran and the IRGC. Again, I'm one of many—certainly not the exception—and the threat is increasing against Iranian diaspora members who are outspoken against the regime and who conduct research, particularly on the security and military intelligence apparatus.
Unfortunately, Iranian diaspora members no longer feel safe in the west. That is the sad reality, and I think that reflects the abject failure in western policy to take action against the regime in Iran, choosing instead to negotiate with it, which has really set a precedent. The regime in Iran believes that it can carry out attacks, it can intimidate and it can conduct these acts of terror without facing any consequence, and that really goes to the root of the problem.
Until the regime in Iran believes that it can't get away with this, my sad prediction is that this will only increase. Given the sizable Iranian diaspora community in Canada, I believe this is a major threat, and proscription can help mitigate against it.
