Perhaps I can start. I can confirm for the committee that I didn't do any work with the federal government or with respect to the CIB during my time at McKinsey.
In my experience at McKinsey, I would occasionally do a pro bono engagement, and that would be the end of things.
As a public servant, the thing that I think we do across all of our projects is follow our procurement policy. When we need to engage external advisers, we engage with the various market participants. We reach out through an RFP or through some form of invitation, solicit feedback from the market and then select the best proposal that delivers the most value for Canadians.
Perhaps Mr. Cory could add something more to that.
