Yes. On matters of national security, there is a potential for federal pre-emption and also under “Peace, Order and good Government” and the emergency part of our federalism Constitution. Just as the Security Offences Act can make both the RCMP and the Attorney General take the lead, I think that this may be an area where Parliament could legislate a federal pre-emption.
I can't guarantee that provinces would not challenge that as an infringement on their constitutional duty under subsection 92(14) for the administration of criminal justice, but I think that's a possibility.
