The 2003 Ontario general election was held on October 2, 2003, to elect the 103 members of the 38th Legislative Assembly (Members of Provincial Parliament, or "MPPs") of the Province of Ontario, Canada. The election was called on September 2 by Premier Ernie Eves to capitalize on an increase in support for the governing Ontario Progressive Conservative Party in the days following the 2003 North American blackout. The election was won, however, by the Ontario Liberal Party, led by Dalton McGuinty.
