I will start, but Mr. Patrice might want to add some elements in there.
We can come back with that regional breakdown.
On the sustainability costs, you're quite right that there are savings. It comes fairly close to cost-neutral when you do all of the math. There's still a cost, but certainly with the investments up front you get a lot of savings over time.
On the issue of the Parliament Welcome Centre, I mean, that really is about balance. It's a significant security enhancement for the precinct. It provides secure screening outside of the footprint of the buildings for the first time on the Hill, and that's fundamental. It very much is a significant security feature that is balanced with creating an open and welcoming environment for visitors to come in, more than doubling the capacity for Canadians to be able to engage into the buildings. That's something we heard from public opinion research as well.
Go ahead, Michel.
