Massé was born in Montreal, Quebec in 1940 and graduated from McGill University and Pembroke College, Oxford (as Rhodes Scholar in 1963). He served as Clerk of the Privy Council in 1979 during the government of Prime Minister Joe Clark. In his distinguished public service career, he also served as President of the Canadian International Development Agency, on two occasions; was undersecretary for external affairs; and represented Canada as its executive director at the International Monetary Fund, World Bank and Inter-American Development Bank.
Massé's career in elected politics began when he ran as a candidate for Jean Chrétien's Liberal Party in the 1993 federal election. He was elected to the House of Commons of Canada as Member of Parliament for Hull—Aylmer.
Following the election, he was appointed to the Canadian Cabinet as Minister of Intergovernmental Affairs, President of the Queen's Privy Council for Canada and Minister responsible for Public Service Renewal.
Massé was re-elected in the 1997 election, but retired from Cabinet in 1999 and resigned his seat in the House of Commons.
In 1985, he was made an Officer of the Order of Canada.
After the Liberal Party of Canada's leadership convention in December 2006 he was asked to join the transition team of newly elected leader Stéphane Dion. He served as Dion's Principal Secretary in the Office of the Leader of the Official Opposition for a period after Dion's selection as leader. He later left the post for health reasons.
