First elected as Member of Parliament for Sudbury in 1988, Diane Marleau has served as Vice-Chair of the National Liberal Party Standing Committee on Policy Development and Chair of the Ontario Liberal Caucus.
Appointed Health Minister in 1993, Ms Marleau made a name for herself as a strong advocate and passionate defender of the Canada Health Act. She has also held the posts of Minister of Public Works and Government Services, Minister for International Cooperation and Minister Responsible for La Francophonie.
In May 2003, Ms Marleau introduced the first-ever Older Adult Justice Act in the House of Commons.

A tireless voice for Sudbury, she has worked with her colleagues in the Northern Ontario Caucus to strengthen FedNor and to see increases in regional development funding. In February 2004, she introduced a motion in the House of Commons calling on the government to develop a strategy that halted the centralization of jobs in larger urban centres.
Re-elected as Vice-Chair of the Standing Committee on Foreign Affairs and International Trade in February 2004, and also serves as a Member of the Standing Committee on the Environment and Sustainable Development.
