I've been with the office for 10 years now. Like my colleagues, I've led several audits, including major work on toxic substances, which implicated Natural Resources Canada quite significantly; a big piece of work on the Great Lakes, which also affected Natural Resources Canada because of its inclusion of water provisions; work on sustainable development strategies; and on a few other topics.
Also, you may not know this, but our office is the chair of an international committee of national audit offices in the business of promoting environmental audits of their national governments. We chair that work, and I lead the work in our group.
