I've been involved in many aircraft introductions, and it's been made very clear by Transport Canada certification that they are not certifying the aircraft for any individual carrier; they're certifying it for the people of Canada.
We generally don't become involved in the discussions on the certification side. They come to an agreement on the certification of the aircraft. Boeing produces the manuals, Transport Canada produces their supplement, and we use that information and determine how we're going to operate our aircraft.
