Howard Hampton was elected leader in at the 1996 Hamilton convention, and led the party through three elections. Hampton's period as leader saw the ONDP lose official party status twice: after the 1999 and 2003 elections. He was able to regain party status the first time after the governing Progressive Conservatives revised party status requirements in accordance with that election's reduction in the number of seats in the legislature, and the second time after winning a string of by-elections in the mid-2000s. The party maintained party status after the 2007 Ontario general election and he stepped down as leader in 2009.
