A lot of it can just be done by people who don't actually have training in one of the traditional or complementary health professions such as those you mentioned. Public health people are being trained in this area in departments of public health, in Canada as well as here.
There's a new name for it now. It used to be called “complementary medicine”, but it's more “partnership medicine” now. I can't remember the buzzword, but increasingly there is evidence that it's beneficial for people in the traditional areas, such as allopathic medicine and nursing and physical therapy, let's say, to be working in a broader context, in partnership with people from chiropractic and naturopathy, and things like that.
So, sure, I think that's the wave of the future.
