His children are Tyler Page, Jesse Page and Chelsey Page. Tyler was killed in 2006 at the age of 20 after being struck by a train while walking home along a railway line near Perth, Ontario, and there is now a bursary in Tyler's name at Algonquin College's Perth campus.
Before being appointed to the position of Parliamentary Budget Officer, on March 25, 2008, Kevin Page had for twenty-seven years worked as a civil servant in the Canadian government with experience in central agencies and line departments including: Finance Canada; the Treasury Board Secretariat; the Privy Council Office; the Department of Fisheries and Oceans; Agriculture and Agri-Food Canada; and Human Resources and Social Development Canada.
In 2017, Page received an Honorary Doctor of Law from Lakehead University.
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."
