Yes, Mr. Chairman. The improvements in internal audit have absolutely contributed to better accountability in government. I believe that deputy ministers are now well served, for the most part, where there are internal audit functions, and they are also well served by their departmental audit committees. So this is clearly a success story.
What I would say, though--and Mr. Ralston perhaps might have some comments in this regard--is that the entire internal audit community in the core federal public service comprises some 400 or 500 people, who I believe are now functioning well for the most part. There are always opportunities for improvement, but it's important to keep that in the context of a core public service with over a quarter of a million people involved. So this is an important function, but it's a relatively small function, and I believe it's largely functioning well.
