I think we're always happy to put the largest share of our budgets into the effective work, as opposed to the monitoring and scrutiny of that work, but a certain amount of evaluation is necessary to ensure you're doing the best job you can. In this case, it helps us to just put in place the best regime that we think we need in Canada. We find it very helpful to compare ourselves internationally. There are some things to help us do this in a very cost-effective fashion. In some cases, for example, more broadly, the International Energy Agency does do reviews of different instruments, such as standards and regulations, and we can use that very cost-effectively without having to do the work ourselves to compare ourselves.
In this particular situation, comparing on a North American basis, some of the metrics are very straightforward. We deal with our American and Mexican colleagues on a regular basis, so in order to draw the information together amongst the three countries would not be a particularly difficult or expensive task. We think it would be one that would pay off significantly in order that we understand the context in which our regime sits in the North American continent.
So without being able to quote you figures or amounts, I can tell you it would definitely be a fairly modest study.
