It's vitally important. We all understand that Canada is a huge country, and the aerospace dimension of Canada is even larger as it extends to seaward. We would be hard pressed with our fighter aircraft to be able to achieve the NORAD mission without refuelling support from tankers. That is a critical element of the NORAD mission, just to be able to cover the geography.
That again is another advantage of working inside this NORAD agreement with the United States. We're able to share our tanker resources with the United States when they require them, but also we're able to draw on U.S. tanker resources for NORAD missions.
