I can ask Mr. Flageole to talk more about it, but, again, we haven't done a lot of follow-up work. We did more work on the enforcement more recently. We did some work on the medical screening, where we did note that there appeared to be improvements. But the new law was just coming in, which would have seemed to have addressed that, so when we did that last audit, in 2003, it was still too early to adequately assess whether the law was having the impacts. This is one of the questions we would like the committee's comments on: Which areas do you think are the most critical for us to begin re-auditing? Is it going back and doing a follow-up of some of that work, or are there new issues we should be looking at?
I don't know if Richard would like to add anything more, perhaps.
