I'm not proposing that you adopt a system exactly the same as the one for terrorist groups, because in the case of terrorist groups you put names on a list without receiving any evidence as to what those groups have done. I'm proposing you wait until sufficient evidence has come from Canadian criminal courts declaring groups to be criminal. Once you have that evidence before you, then Governor in Council or Parliament can put that name on a list.
