Yes, but it's about some of them even getting here. There are instruments already that do these sorts of things.
If I remember correctly, the Immigration and Refugee Protection Act, for example, has been used against other countries. If I remember correctly, after what some people call the “coup” in Egypt that removed the Muslim Brotherhood, for a time, using the Immigration and Refugee Protection Act, we weren't allowing anybody who had done any military service in Egypt to come to Canada, and the Egyptian military wasn't a designated terrorist organization. Why that can't be applied to IRGC members applying to come to Canada I don't know. As I mentioned earlier, I'm not a lawyer.
You're right that in terms of activities that are done here, yes, there's a judicial process, and that could happen with or without their being.... If we find they're up to some nefarious activities here, be it money laundering or supporting terrorist organizations or whatever it might be, there are deportation measures that could be taken against them, whether or not we have listed their organization, or if they've committed crimes or broken any laws, they could be arrested and charged.
Again, I'm not sure what this adds, but there is value in the symbolic acts.
