Thank you. I would say it's a great pleasure to be back—maybe not every day.
Obviously, that's a question that's really properly for the Canada Infrastructure Bank. I think what that demonstrates, though, is that the CIB can take different approaches, and I think that's really important. We're going to have to figure out how we're going to get a ton of infrastructure built. It's estimated that $3 trillion is the cost to transition to a clean energy future globally. That's a huge cost, and we need to figure out the different models to do that.
If you look at the program that the Canada Infrastructure Bank has for electric buses, it's actually managing to electrify buses across the country at a rate that would not be possible without the Canada Infrastructure Bank. However, as you point out, this isn't like a traditional public-private partnership. The bank clearly is looking at different opportunities in its flexibility.
One thing I want to point out is that the bank should look at doing investments in indigenous infrastructure in partnership with indigenous peoples, where indigenous peoples have an equity stake. This is a real opportunity for Canada to think outside the box. I think it's extremely important, and it was certainly important to me when I was minister.
It's interesting. I just want to point out that other countries are looking at this model. If you look at the U.K., they have created an infrastructure bank based on Canada's model, because they see it as a huge opportunity to get more infrastructure built too.
