Yes, Chair, we certainly do that in the department, although I would say the nature of the evaluation depends very much on the subject matter. In fact, all across the government, there is a requirement to evaluate the environmental costs and benefits of actions by government.
We have the privilege, I guess, of being in a position where if we develop policy advice, and it's accepted by the government and it's good environmental policy, the net benefit to the environment is going to be pretty clear. But we do in fact go through that discipline of providing government with the analysis within the context of the information and data available.
