Sure. Those considerations are paramount. If we take safety, for instance, every foreign carrier has to be certified by Transport Canada. We make sure in that process that they meet our safety requirements in order to be allowed to fly in Canadian airspace. If a foreign carrier wants to come to Canada for the first time, it will have to go through a process that Transport Canada is responsible for, which may include base inspections and various things like that, before it can get its air operator certificate. That's on the safety side.
On the security side, Transport Canada also ensures that the foreign carrier meets our security requirements. There is also a process in place to assess that, which may include base inspections. Transport Canada officials, security inspectors, would go into the other country to inspect the base to make sure they meet our requirements.
