I wish I were an expert in this area. I will beg off and say I'm not sure that the new Accessible Canada Act has been compared to the regulations in detail. I presume that Transport Canada is doing that and recommending changes to the APPR to match.
I've seen the same stories that you've seen. Unfortunately, we're not a disability rights group, so I don't have better information. I'd throw it to any of the other witnesses, if they can answer it.
