In answer to your first question, there's no impact to the standing roles and missions of the F-18 in the Royal Canadian Air Force. Our NORAD commitments are met and both of these deployments fall within our expeditionary capability with redundancy. That's actually an area that I'm responsible for day-to-day, so I can say that quite confidently.
With respect to the length of time of this Baltic air policing mission, our block that we signed up for finishes at the end of this year, and the plan right now is that our F-18s will return shortly thereafter.
