Liberal Leader Dalton McGuinty's record was the subject of choice for party leaders vying for voter attention in the last weekend before the provincial election.

Progressive Conservative Leader John Tory accused McGuinty of misleading the public about the costs around building a hospital in Sarnia. On Saturday afternoon he brought up a newspaper article which cited information the hospital could cost double what the Liberals originally said it would.

Tory said it could be grounds for an audit or criminal probe.

"If you want an example of how badly Dalton McGuinty mismanages the projects he invests your tax dollars in, look no further than right here in Sarnia," Tory said.

NDP Leader Howard Hampton also took shots at McGuinty Saturday, saying voters are still uncomfortable choosing him to lead the province for a second term.

"They know he will say and promise anything and that all those promises mean nothing the day after the election," Hampton told reporters while campaigning in Toronto.

According to recent polls, McGuinty has a comfortable lead with over 40 per cent of the votes. Tory trails behind with just over 30 per cent support, and Hampton is expected to receive about 18 per cent of the votes.

Tory and Hampton tried hard to stay away from the controversial Conservative promise to fund faith-based schools, a topic that has dominated most of the campaign.

McGuinty on the other hand, was happy to speak about his party's position on the topic during a campaign stop in Markham, where he spoke to a crowd of Asian-Canadian supporters.

"Any issue that affects two million students I think is pretty powerful," he said when asked why he keeps talking about the issue. "You reach a lot of homes when you start talking about the future of publicly funded education and the great thing about this election and this campaign is people now have a very clear choice."
