If I might, I think there are a lot of areas where it's certainly impossible to draw that bright line with respect to research. Gary mentioned clinical trials and the use of the information by pharmaceutical companies to get the word out to physicians about clinical trial work. I think we'd all agree that clinical trials are health research. So where do you draw the line there? Where do you draw the line when you're talking about providing information and education about particular products and services to the health profession groups?
So I think it's difficult in many cases to distinguish between purely commercial purposes and research purposes. And the other thing we have to remember, of course, is that in Canada these days much of the health research that's conducted, on pharmaceuticals in particular, is conducted by the private sector.
