I'll weigh in very quickly to leave this question with some substance.
Our goal is to create some labour mobility. If I'm a mechanical contractor doing business in Quebec, as an example, and my workers' jobs dry up a bit, my credentials should be recognized in British Columbia as the same skill set. We're trying to work towards that. We're not there yet, but we're trying to get other provinces on the same page to recognize the credentials of apprentices and journeypeople across the country.
In fact, it's even a north-south situation. We should be able to recognize Canadians going to the States and Americans coming to Canada with the same credentials.
