No Option Nationale candidates were elected in the ensuing election; Aussant lost his seat to a Coalition Avenir Québec candidate. On June 19, 2013, Aussant left his role as leader of the party. He stated "family and personal matters" as the official reason. In August of the same year, he announced that he would be leaving Quebec to work once again with Morgan Stanley Capital International in Britain. He noted that he had not received job offers from Quebec employers and speculated that his involvement in the Quebec separatist movement may have been the reason. Aussant rejoined the Parti Québécois, and ran as its candidate in the 2018 election in the riding of Pointe-aux-Trembles. However, he was defeated.
