Certainly we attempt to look five years out. As you know, we're not funded five years out, but we always try to have an eye towards the rolling calculus. In that degree, we would rely to a certain extent on our research and statistical division, which would tell us what the trends are in things like release rates and program participation. We would attempt, based on things like the average age of a veteran, to extrapolate on use of programs today and into the future.
We'd also, though, from a sustainability point of view, look at program design and whether the needs of the veterans are evolving in a different way that would require us to change programs and change costing. For example, we're in the early stages of looking at mental health issues, because we anticipate, as we do with the Canadian health system writ large, challenges as we move forward. The physical issues that veterans face are treatable, and the costs are known. The mental impacts are tougher to quantify and therefore we're always looking at our program design from that point of view.
From the perspective of sustainability, we are always trying to attend to the needs of the veteran but up front to be more proactive around mitigating them or preventing them entirely through good things like appropriate rehabilitation and other psychosocial programs we have.
