1999 Ontario general election

The Ontario Legislature after the 1999 election.

According to a poll released on the eve of the election, the Liberal Party entered the campaign with a lead over the Progressive Conservatives. This poll's accuracy was disputed by many, however, and even Liberal leader Dalton McGuinty cast doubt on it: noting that most polling companies claim to be accurate 19 times out of 20, he suggested that this might have been the 20th. Subsequent polls taken in the early period of the campaign showed the Progressive Conservatives with a commanding lead over the Liberals, in a manner more consistent with pre-election numbers.

Harris' government had delivered large tax cuts and significantly reduced the deficit, but they had also severely cut spending in the process. They had the support of the legendary Tory political machine, bolstered by a group of American experts imported from the United States' Republican Party. They targeted Dalton McGuinty as inexperienced ("Dalton McGuinty is not up to the job" was a Tory campaign slogan), and attacked him for lacking a clear vision. This was successful due to McGuinty having a reputation for being uncomfortable and stiff in the media. During the leader's debates, McGuinty had a poor performance, being unable to explain his party's platform clearly and being compared to fictional serial killer Norman Bates by NDP leader Howard Hampton.

The extensive use of attack ads and wedge issues by the Tories was a new development in Canadian politics, and some commentators worried the election process was becoming Americanized.

The third major party, the Ontario New Democratic Party led by Howard Hampton, spent much the campaign battling the memory of Bob Rae's unpopular government in the early 1990s. Despite Hampton's efforts to reach out to labour, the NDP were substantially weakened as the major unions deserted them in favour of the Liberals, hoping to defeat the Tories by strategic voting.

The province was enjoying strong economic growth at the time which also vindicated the Conservatives' deficit-cutting measures in the public. The Liberal Party managed to recover some support late in the campaign, but it was not enough and the Tories were re-elected with a second consecutive majority government.

Among the independent candidates were slates fielded by several unregistered parties:

• 27 candidates were affiliated with the Communist Party of Canada - Marxist-Leninist. These candidates won a total of 7,194 votes.
• Three were members of the Humanist Party of Ontario.

It is possible that some independent candidates were actually members of these or other unregistered parties.

Expenditure entries are taken from official candidate reports as listed by Elections Ontario. The figures cited are the "Total Candidate's Campaign Expenses Subject to Limitation", and include transfers from constituency associations.

The official returns incorrectly list Ray as a candidate of the Ontario Communist Party, rather than the Communist League.
