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, the group won two seats in the Legislative Assembly of Ontario: A.A. MacLeod and J.B. Salsberg served as Members of Provincial Parliament (MPPs) from 1943 until 1951 and 1955 respectively. It has not been able to win any seats at the provincial level since then. The party continued to run under the Labor-Progressive banner up to the 1959 provincial election, after which it identified itself as the Communist Party.
