Toxic industrial materials are certainly the most probable threat in a CBRN portfolio that we would face, I believe, in Canada. It's the most probable.
To be more general in a response to your question, sir, CJOC isn't responsible per se for threat assessments. It is the chief of defence intelligence who does that and analyzes all of the information and offers a threat assessment, or the civilian counterparts would also do that.
It is my sense that our military threat assessments have largely been based on the previous generations of threats, which were characterized by intentions and capabilities. Given the unpredictable nature of the current situation and the adversary, the factor of vulnerability is an interesting one from an operational perspective. It's not only considering from the adversary's perspective, their capability and intent, but perhaps from our perspective considering vulnerability and somehow rolling that in. I don't know that we've taken that to the level where it's useful yet.
