The 1943 Ontario Liberal Party leadership election was held on April 30, 1943, at the King Edward Hotel in Toronto to choose a new leader of the Ontario Liberal Party. The convention was won on the first ballot by Harry Nixon, who succeeded Gordon Daniel Conant as party leader and subsequently became Premier of Ontario.
The leadership contest followed the resignation of former premier Mitchell Hepburn, who had left office in October 1942 after a period of internal conflict within the Liberal government and party. Hepburn was succeeded as premier by Conant, who had served as attorney general. Because the Liberals were still in government, the leadership race also determined who would become premier.
Conant initially sought to remain leader and premier, but he withdrew from the race after suffering a collapse shortly before the convention vote. With Conant hospitalized, Thomas McQuesten was serving as acting premier on the day Nixon was elected leader.Conant Suffers Collapse, Quits Leadership Race Toronto Daily Star April 30, 1943Nixon's Ontario Premier But Question Is When?

Background
The leadership contest took place during the final months of the Liberal government first elected under Mitchell Hepburn in the 1934 Ontario general election. Hepburn resigned as premier in October 1942 and was succeeded by Gordon Daniel Conant, who had served as attorney general in Hepburn's government.Gordon Daniel Conant https://www.ola.org/en/members/all/gordon-daniel-conant Legislative Assembly of Ontario May 31, 2026
Although Conant became premier, the question of the permanent party leadership remained unsettled. A leadership convention was called for April 1943, less than four months before the 1943 Ontario general election. Because the Liberals were still in office, the convention would also determine who was expected to become premier.Nixon's Ontario Premier But Question Is When? Toronto Daily Star May 1, 1943
