First of all, the process is one where the assistant deputy minister of materiel at National Defence has to request it. I would send a formal letter to my counterparts in Public Works, who, as I mentioned to Monsieur Bachand, do a legal review of that. There is an evaluation of that, and they have the authority to approve or not approve it. So they will write me back.
The criterion is normally the ability to ensure that the in-service support of a key piece of equipment is done in Canada with sufficient guarantees that a Canadian firm with access to a reserve of spare parts can ensure the operation of that equipment in a time of emergency when perhaps another country would have different priorities. This is so we'd have assured support and availability of that key equipment. And that's the main criterion that we use. That's the main time we'd consider a national security exception to the agreement on internal trade.
