The 1929 Ontario general election was the 18th general election held in the Province of Ontario, Canada. It was held on October 30, 1929, to elect the 112 Members of the 18th Legislative Assembly of Ontario ("MLAs").

Campaign

Every party, including the Ontario Prohibition Union and the English Language School League, issued their own manifesto during the campaign, to the extent that the Press called it the "battle of the manifestos". The Liberals continued to use their strategy from the previous election of coordinating their efforts with other pro-temperance forces in order to minimize vote splits. Only the Conservatives fielded candidates in all ridings, and eight of them were returned by acclamation. In 21 two-way contests, the Liberals declined to field a candidate in favour of an ally considered more likely to gain votes. There were only 16 three-cornered races and 2 four-way battles.

Outcome

The Ontario Conservative Party, led by George Howard Ferguson, was elected for a third consecutive term in government with an increased majority in the Legislature. The Ontario Liberal Party, led by W.E.N. Sinclair, lost one seat, but continued to form the official opposition. Conservative gains came at the expense of the Progressive Party and the United Farmers of Ontario. Earl Hutchinson of Kenora is the sole Labour MLA elected.
