In 2009, Cauchon indicated he was interested in re-entering politics and running in his former riding of Outremont, which was then held by New Democratic Party (NDP) Deputy Leader Thomas Mulcair. The Liberal Party's Quebec Lieutenant Denis Coderre, who was tasked with finding Quebec candidates for the next election, announced that the riding was closed off to Cauchon and was being reserved for a female candidate.
