To be fair, I was focusing on completion rates. The different structure didn't seem to matter as much as I thought it would have a priori, so if there are good reasons for that regional variation, it doesn't seem there's too much cost in terms of completions. Certainly, my results don't speak to saying we should move to a single system.
Red Seal is in place, as Andrew said, so that does allow somebody who qualifies, say, in Nova Scotia, to then go further and get the qualification that allows them to move throughout Canada. Presumably, a single program would do that in one step, in some sense, but I don't think the Red Seal is a particularly large cost on individuals. Again, if there are differences in regional economies that would suggest differences in programs, then moving to a single program could be costly.
