Mr. Chair, I'll speak to that initially.
If we do find that there's a situation where we feel that there is a threat to Canadian airspace, to individuals operating within Canadian airspace or to Canadians themselves, we will liaise through a protocol with our Canadian Forces colleagues to take decisions on what may be required to address that threat. Nav Canada will be helping us inform potential areas where the threat is located, but they will also be part of our conversation to make sure that we're able to address that threat effectively.
