Yes, we have a funding protocol with Treasury Board that's called our national investment strategy. With that, we assume that 4% of the inventory should be off-line every year for retrofit. And from that, we apply a factor of around $1,800 per metre to carry out the retrofit of the assets. That translates into, for our crown-owned facilities, about $200 million a year that we have available for capital improvement and capital upgrades to the assets themselves.
Part of our challenge is that the national investment strategy didn't come into effect until the mid-1990s. We're still dealing with a huge backlog of deferred maintenance. We just haven't had the opportunity to get caught up to that level.
The other issue is that it's not price-protected. Although there's a formula in place, every year your spending dollar gets eroded by the impact of inflation.
So that's been our challenge.
