Hivon was first candidate for the PQ in 2007 but lost to then-health minister Philippe Couillard in the riding of Jean-Talon.

The premier at the time, Pauline Marois, named her Minister of Social Services and Youth Protection.

In the 2014 Quebec general election, Hivon was again re-elected to the National Assembly but as a member in the opposition rather than in the government.

On December 1, 2015, the Quebec Superior Court suspended the Act Respecting End-of-Life Care, declaring it unconstitutional.
