That's an excellent point, and we have certainly heard from a number of northern operators who have in fact been, as you pointed out, retrofitting aircraft and really extending the life of aircraft that have been around for quite some time to address the issue of gravel strips in many of these communities.
The new aircraft—and not even new aircraft—that have been coming on stream over the last few years are not capable of landing on these strips. The gravel kits that used to be available for some of the aircraft that are still servicing these communities are becoming scarcer and scarcer. So, from the perspective of accessibility to many of these communities, but also from a safety perspective in the long run, it's something that I think Canada needs to address, because if these communities are to continue to be a part of our national transportation system—such that the residents of these communities are equal Canadians who can access the rest of the country in a safe, efficient and cost-effective way—we need to look at paving these runways. Obviously, from a budgetary perspective there are limits on how many you can do and how much you can do, but unless we get started on this, it is simply a problem that's just going to keep on getting pushed further and further down priority lists.
