2009 Ontario New Democratic Party leadership election

The 2009 Ontario New Democratic Party leadership election was held in Hamilton, from March 6 to 8, 2009 to elect a successor to Howard Hampton as leader of the Ontario New Democratic Party (NDP). On June 15, 2008, Hampton informed the party's provincial council that he would not stand for re-election as leader at the next party convention in a year's time.[2][3] While a leadership vote was held at each biennial convention of the Ontario NDP until and including the last regular convention in 2007, there is normally not a contested vote unless there is a vacancy, therefore, the 2009 vote was the party's first leadership convention since Hampton was elected in 1996 to succeed Bob Rae.
