That's probably a question better answered by some of the individual business players in the transportation sector.
One of the other challenges we hear—and this is particularly arising in western Canada right now—is that it's hard to keep people in the transportation sector when the energy industry is so attractive and offers longer periods of time off, longer holidays, and better pay. There are challenges around the attractiveness of the industry, so flexibility.... It may be that it's from a rational point of view that people are choosing other sectors for what, at the individual level, are good reasons.
At the same time, the transportation sector offers some very interesting work, and it's much less likely to be labour-intensive. There are new technologies that make the jobs more interesting, so hopefully they'll attract new people.
