We're looking at some of the international benchmarks, so, for instance, right now Canada is spending less than 0.3%, and we're talking about beginning at 0.7% of GDP and moving up to 1%. A target could be achieved by—I'm just looking at my notes because the numbers in my head are not the easiest—increments of $1.5 billion annually.
It's not going to all happen in the first year, we understand that, and the system needs to grow. It will be a significant investment, as Paul said, but it does, I still say, pay for itself and beyond.
