As I said earlier, this is a part of a suite of tools to make sure that the minister has the ability to protect the safety and security of supply chains.
In terms of a threat, it could be anything. Remember, it's a threat to safety and security, competition or national economic security, so it's one of those three factors. A threat could be, for example, that a port shut down or that a terminal operator decided that—I believe my colleague used this example when she was here last week—it was no longer going to accept goods from a country, or something like that.
I think back to COVID and protective equipment and those sorts of things. Is that a threat? I don't know, but there are lots of threats that could happen in the transportation space. I could come back to you with one. We haven't yet encountered anything in that regard.
Again, I think about natural disasters on the west coast. There could be the pandemic itself. Depending on what the threat is, again, this is a measure of last resort and not something that would be meant to be implemented or used in a light fashion; it would be used in case of an emergency.
We would need to look at the situation and the instances, the factors at the time, do the assessment, work with our colleagues to see whether or not the threat is real, assess it and give the best advice to the minister, and then take it forward. This is something that neither the department nor the minister would be advancing lightly.
