On the debt-to-GDP ratio as a measure, obviously there are many ways to tabulate a country's debt. We often hear the government making reference to the debt-to-GDP ratio. I think there's very good reason for that, but it's important to put on the record why debt-to-GDP ratio is the go-to, so to speak, for the Government of Canada. Maybe you can add something about the IMF in terms of your interactions with the organization. They seem to take it very seriously as well.
Why is it that particular measure as opposed to others? What does it add that others don't?
