I might be able to briefly address Ms. Leitch's question. I think part of the issue for medical doctors is that they have their own governing bodies in each profession. In Ontario, the government has begun to do that by establishing the Ontario College of Trades. I was in the government at the time. The idea behind this entity is really to provide the profile and the central planning for the trades in the same the way it is done for the professions.
As you can imagine, it is somewhat more unwieldy, because you are talking about hundreds and hundreds of trades rather than one profession. Nevertheless, I think it is something that is needed. You need to be able to centrally plan this if you're going to have true mobility between the provinces. That has always been an issue. Ontario has begun to go that way. It is still very much in its infancy, but I can tell you that the mobility issue was one of the main reasons for doing it.
