The Ontario general election of 1987 was held on September 10, 1987, to elect members of the 34th Legislative Assembly of the Province of Ontario, Canada.
The governing Ontario Liberal Party, led by David Peterson, was returned to power with their first majority government in half a century, and the second-largest majority government in the province's history. Peterson had successfully managed to govern with a minority in the Legislature by obtaining the co-operation of the Ontario New Democratic Party, led by Bob Rae. It was through the NDP's support that Peterson was able to form a government, even though the Progressive Conservative Party had won a slightly larger number of seats in the previous election.
The PC Party, led by Larry Grossman, campaigned on a platform of tax cuts to stimulate the economy. Its support continued to slide, however, as voters opted for the change that the Liberal-NDP arrangement provided, with even Grossman losing his own seat. The NDP was unable to convince voters that it should be given credit for the success of the Liberal government that it had supported. Despite losing six seats, the party became the Official Opposition for the second time in the party's history. The PCs fell to 16 seats and third place in the legislature, their worst showing in an election in half a century.
