Two seats were won by the Labor-Progressive Party on its own with the re-election of A.A. MacLeod and J.B. Salsberg. The LPP contested a total of 31 ridings under the leadership of Leslie Morris who was defeated in the Toronto riding of Bracondale. As well, the Labor-Progressive Party ran several joint candidates with the Liberals under the Liberal-Labour banner.
The Drew government called the election in an attempt to get a majority government. By exploiting increasing Cold War tensions, the PC Party was able to defeat Jolliffe's CCF by stoking fears about communism. Jolliffe replied by giving a radio speech (written by Lister Sinclair) that accused Drew of running a political gestapo in Ontario, alleging that a secret department of the Ontario Provincial Police was acting as a political police spying on the opposition and the media. This accusation led to a backlash, and loss of support for the CCF, including the loss of Jolliffe's own seat of York South. This probably helped Drew win his majority, although in the 1970s, archival evidence was discovered proving the charge.
