Using the name Labor-Progressive Party from 1943 until 1959, the group won two seats in the Legislative Assembly of Ontario: A.A. MacLeod and J.B. Salsberg were elected in the 1943 provincial election as "Labour" candidates but took their seats as members of the Labor-Progressive Party, which the banned Communist Party launched as its public face in a convention held on August 21 and 22, 1943, shortly after both the August 4 provincial election and the August 7 election of Communist Fred Rose to the House of Commons in a Montreal by-election.
Parent, who was also president of UAW Local 195, was elected as the Liberal-Labour MPP for Essex North in 1945.
In January 1946, Parent announced he was breaking with the "reactionary" Liberals and sat the remainder of his term in the legislature as a Labour representative while voting with LPP MPPs MacLeod and Salsberg.
