I'll pass it over to Ms. Garrett in a second.
There are just a couple of things there, and I'll branch back on the Visitor Welcome Centre to just add a piece to what Mr. Patrice said. The main part of the Visitor Welcome Centre will interconnect with the Parliament Welcome Centre as well, and that is part of making that one integrated facility, so a lot of those investments will be reused, if you will, as well, in addition to what Mr. Patrice indicated.
On the courtyards, it's important to note that those were inaccessible, unused courtyards before, so you couldn't get into them. I would see this as more of a bonus for the building rather than taking anything away.
As far as the greening of the Hill goes, that's a major part of the long-term vision and plan. In the public opinion research that Mr. Patrice mentioned, that was one issue that came back from the public as well.
I'll pass it over to Ms. Garrett to speak more about the sustainability efforts.
