We have some research coming out tomorrow on this, and I'd be pleased to share it with you. I believe it's New Brunswick that already takes the disability tax credit and bases its provincial disability assistance on the DTC. There is a sharing of a list there that has already happened.
I do wonder why that hasn't been able to.... Obviously there's protection of data, and there's federal and provincial jurisdiction and so forth, but they figured it out at a very basic and technical level, and I think it would be pretty interesting if the other provinces could figure out how to do the same thing.
