The Rotman school in Toronto did a really wonderful job looking at the economic benefits of accessibility. I think it's called “Unleashing....” I can't remember, but it was done back about 10 years ago, and it looked at the economic benefits that come from increased accessibility.
It was, I think, a really well-done methodology, and I think it was very clear. The other thing is, what's the cost of the barriers now? The costs are extraordinary in terms decreased productivity, reliance on social assistance and things of that sort. The costs are tremendous now. I think the economic benefits are really quite important.
