Canada government of William Lyon Mackenzie King, which, Hepburn argued, was insufficiently supportive of the war effort. The battle between Hepburn and King split the Ontario Liberal Party and led to Hepburn's ouster as leader. It also contributed to the party's defeat in the 1943 election, which was followed by the party's long stint in opposition. The Liberals declined to a right wing, rural rump. The "Progressive Conservatives" under George Drew established a dynasty which was to rule Ontario for the next 42 years. Opposition during the Post-War boom Ontario politics in recent times have been dominated by the Progressive Conservatives, also known as the Tories. The Liberals had formed the Government for only five years out of sixty years from 1943 to 2003. For forty-two years, from 1943 to 1985, the province was governed by the Tories. During this period, the Ontario Liberal Party was a rural, conservative rump with a southwestern Ontario base, and were often further to the right of the moderate Red Tory Conservative administrations. In 1964, the party changed their name from the "Ontario Liberal Association" to the "Liberal Party of Ontario". In September 1964, the party elected Andy Thompson as its leader. While the leadership election garnered some attention, it looked like Thompson would have a hard time winning an election. The Liberals had held office only three times for 13 years since 1900 and the party caucus was not that much different from the time between 1959 and 1963. They failed to get a popular candidate, Charles Templeton, elected in a by-election. They also lost another riding to the PCs when Maurice Bélanger died in March 1964. Thompson would last only two years as leader before resigning due to stress-induced health problems. Throughout the 1960s and 1970s, the Liberals were almost shut out of Metropolitan Toronto and other urban areas and, in 1975, fell to third place behind the Ontario New Democratic Party (NDP) under Stephen Lewis. With the NDP in ascendancy in the late 1960s and 1970s, it appeared that the Liberals could disappear altogether. The Liberals remained more popular than the Tories among Catholic and Francophone voters, due to the party's support for extending separate school funding to include Grades 11–13. The Tories opposed this extension until 1985, when they suddenly reversed their position. This reversal angered traditional Conservative voters, and may have contributed to their defeat in the 1985 election.
