We would raise the matter with the Office of the Auditor General. I can only assume--and as this is hypothetical, I will--that the way it would need to be addressed is that the office would look at that particular audit, and if there were a need to do another one or to redo some of the work to actually provide that level of assurance, I'm quite sure they would.
