His approach of questioning government estimates and issuing reports that are at odds with official government forecasts has created controversy. "There are former parliamentarians saying I should be held in contempt of Parliament and should be fired, but I’m okay with them saying that. That’s just part of the debate." He has been unapologetic about his Desire to give the Parliamentary Budget Office a significant role in informing Parliament and Canadians about government finances, saying "I went to the OECD, and they said the Americans have the best budget office, bar none. Why can't we be the best in five years? If that's overstepping my mandate, then I'm earning my money."
