Unfortunately, we don't have statistics on this. That's part and parcel of the problem. It's a whole larger set of problems. It's not just about disability-related issues, although those issues are prominent. If you look at the U.S. DOT statistics, it's a treasure trove of statistics. It makes every mathematician and statistician salivate, looking at how much data they have and how much research you can do on that.
We don't have anything like that in Canada. While Statistics Canada has some data, they're not allowed to release that data because of legal restrictions.
