Giving you a rating may be difficult, but let me tell you that over the last six years, for sure, we have looked in detail into their sustainable development strategies, so that's what it looks like. It's the department's game plan to move on a sustainable path with respect to its mandate. We have come out with pretty good marks over time. For an auditor, a department will never be perfect, but NRCan has done a lot of work to move on a sustainable path.
I will let Neil tell you a little more, because he's the expert in the SDSs.
