Absolutely.
Let me just start by saying that our initial assumption was that we wouldn't be touching too much on infrastructure, because that would have been outside the scope of transportation. However, as we delved more deeply into this and looked at what other jurisdictions have done in their management of transportation policy, infrastructure was very much a part of how they positioned themselves.
In the north, we would define infrastructure, basically, as the basic building blocks on how you move people and goods. That would involve ports, airports, roads, and rail. But, obviously, in the north rail and roads aren't as prevalent, so in the north it would be more ports and airports, but more particularly airports.
In the case of the north and airports, unlike a lot of other northern jurisdictions, we found that in Canada with our user-pay model and practice over the years, we have northern communities that still rely on gravel airstrips for access. It's their only form of access in and out of those communities. The reason we felt that infrastructure was a key component of any look at northern transportation was that for many of these communities, those gravel strips have a very finite lifeline just because the aircraft servicing them are getting very old. We're getting to a point where there are no replacement aircraft of similar size that are capable of landing on gravel strips. Without addressing the fundamental infrastructure issues that are present, particularly in the north, we didn't feel that any transportation study would be complete.
