With the Parti Québécois forming the government, Blanchet became parliamentary assistant for the Minister of Labour.
She decided not to run again in the 2003 election, and the riding was won by Michèle Lamquin-Éthier of the Liberals.
After her time in the National Assembly, Blanchet returned to banking, serving as a teller at the Caisse Desjardins in Saint-Eustache Deux-Montagnes from 2005 to 2013.
When Lucie Papineau resigned her position as chief of staff for Nicole Leger, the Ministry of Families as a result of the Charbonneau Commission, Blanchet stepped in to take her place.
