We don't have them in Canada, but I recommend that you refer to a report of the Institute of Medicine in the U.S., which was published three weeks ago. It produced a very important and interesting analysis of the waste in the U.S. health care system. Although we have to be careful in not equating things, as our systems are very different, I think there are a number of things that you will find are akin to what's happening here.
