belonged to the Ginger Group, and some members of the League for Social Reconstruction (LSR), the CCF was formed, making J. S. Woodsworth the de facto leader, and giving responsibility for organizing Ontario to Agnes Macphail of the UFO. Macphail, as president of the Ontario Provincial Council, persuaded her fellow delegates at the December 1932 UFO convention to affiliate with the CCF provincial council. After the 1933 Regina convention, the name of the party was introduced as the Co-operative Commonwealth Federation (Ontario Section) – The Farmer-Labor Party, though the shorter Ontario CCF was the most commonly used name. Macphail served as the first chairman of the Ontario CCF from 1932 until 1934. As a UFO Member of Parliament (MP) in the Canadian House of Commons, she was forced to resign from the CCF after the UFO withdrew from the party after alleging communist influence in it. Consequently, the UFO's two candidates in the 1934 provincial election, including longtime MLA Farquhar Oliver, ran under the UFO banner rather than with the CCF. Oliver was elected and later joined the Liberals. Macphail later served in the Legislative Assembly of Ontario as the CCF Member of Provincial Parliament (MPP) for York East from 1943 to 1945 and again from 1948 to 1951. Samuel Lawrence, an Independent Labour Party member of Hamilton City Council, was elected to the Ontario legislature as a CCF MPP in the 1934 provincial election, the first Ontario election contested by the CCF. The party received 7.1 percent of the vote and, with Lawrence's election in Hamilton East, won its first seat in the Ontario Legislature. The Ontario CCF failed to win any seats in the 1937 election. He was elected Ontario CCF president in 1941. and served as Mayor of Hamilton from 1944 to 1949 leading a CCF slate in that city. Alderman John Mitchell of Hamilton was elected the first Ontario CCF president in 1934 as part of a reorganization of the party after its provincial council had been suspended by federal leader J. S. Woodsworth for suspected communist infiltration. The reorganization created a new provincial council and central party executive and centralized what had been a loose structure of affiliate organizations and riding clubs. It was accompanied by a purge of party clubs and affiliates suspected of having been infiltrated by Communists and the removal of suspected Communists from senior party positions. The reorganization was prompted by
