York South was an electoral district (or "riding") in Ontario, Canada, that was represented in the House of Commons of Canada from 1904 to 1979.
The riding is notable for the 1942 federal by-election in which newly elected Conservative leader Arthur Meighen was defeated in his attempt to win a seat in the House of Commons by the Co-operative Commonwealth Federation's (CCF) candidate (assisted by the Liberals). The election was a major breakthrough for the CCF, and ended Meighen's attempt to return to politics. In later years, it became known as perennial leaders' riding, the home district for both CCF and New Democratic Party (NDP) leaders Ted Jolliffe, Donald C. MacDonald, David Lewis and Bob Rae.
