It's now a three way race to find a successor to former Ontario PC party leader Patrick Brown.
Caroline Mulroney, a Toronto lawyer and the daughter of former prime minister Brian Mulroney has entered the race.
The 43 year old mother of four says despite Brown's sudden resignation she believes the Tories can come together and win the June 7th election.
Mulroney is up against former Toronto city councillor Doug Ford and former MPP Christine Elliot.
The leadership race will be decided March 10th.
