In looking across all of our mandate and everything we are supposed to audit, first of all, we have a mandate to audit financial statements of the federal government, the government of the three territories, and crown corporations. Those financial statement audits we do every year on all of those organizations.
We have a mandate to do special examinations of the systems and practices that exist within federal crown corporations, and we have to do a special examination of each crown corporation at least once every 10 years—at least, of all those listed in the Financial Administration Act, which is most of them. We have to do that special examination once every 10 years.
There are certain things, then, that we have to do, that we are legislated to do.
In terms of our performance audits, we look across the federal government. We've divided the federal government, I suppose, into a number of envelopes, whether international affairs, the environment, aboriginal affairs—those types of things—and then we will do what we call a strategic audit plan to try to identify the risks in those areas. It's not so much about looking really at a particular department as about looking at an area and doing a strategic audit plan that looks at all of the departments within that area, looking at the types of programs they offer and the risks associated with them. Then, the ones in which we feel there is the most risk that something needs to be improved will be the ones we select for a performance audit.
