The 1982 Ontario New Democratic Party leadership election was held in Toronto, Ontario, on February 7, 1982, to elect a successor to Michael Cassidy as leader of the Ontario New Democratic Party (NDP). The convention was necessary because Cassidy resigned after the party's poor showing in the 1981 election. Bob Rae was an overwhelming favourite and this continued into the convention which Rae won on the first ballot. Rae went on to lead his party to their first election win in 1990.
