The Communist Party of Canada (Ontario) (French: Parti communiste du Canada (Ontario)) is the Ontario provincial wing of the Communist Party of Canada. 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.^[2]

MacLeod and Salsberg served as Members of Provincial Parliament (MPPs) from 1943 until 1951 and 1955 respectively. A third LPP member, Alexander A. 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.^[3][4] He did not run for re-election in 1948.

The party has not been able to win any seats at the provincial level since Salsberg's defeat in 1955. The party continued to run under the Labor-Progressive banner up to the 1959 provincial election, after which it again identified itself as the Communist Party.

Individual members of the party have been elected to school boards in the past few decades, but have done so as independents rather than as "Communist Party" candidates. Since 2019, the party has been led by Drew Garvie.
