In relation to your question about the Auditor General's role as a protector versus being backward-looking in terms of the audit function, I would say it is consistent with the traditional model of agents of Parliament generally in Canada, as they actually focus on compliance with broad policies. The Auditor General acts within a legislative mandate. The Commissioner of the Environment and Sustainable Development actually has a key role with respect to sustainable development strategies and tracking those and reporting on progress against implementation against those.
There is a debate out there too about the extent to which the audit function is only backward-looking. I've been involved in a lot of audits during my public service career with the Auditor General, and while you do look back in terms of what actions have been taken, the recommendations that are put out actually have, very often, a very significant change in terms of how you move forward.
So I don't think it's quite a black and white issue in this application.
