Career
Champagne worked as a teacher in French and history from 1964 to 1971 at the secondary level Before her political career she was the political secretary for Champlain MNA Yves Beaumier from 1997 to 2003. She ran as a Parti Québécois (Province of Quebec) candidate in the district of Champlain in the 2003 election (on April 14), which resulted in a tie vote.
A subsequent by-election was necessary to break the tie, and it gave Champagne, who became the 45th Province of Quebec MNA to the new assembly, the victory over Liberal candidate and former MNA Pierre-A. Brouillette by 642 votes.
She was defeated in the 2014 election.
