With just a week to go before voters head to the polls, the three main party leaders spread out across southern Ontario today in an effort to drum up votes.

Progressive Conservative Leader Tim Hudak has an event in Ottawa, NDP Leader Andrea Horwath visits Welland, Port Colborne, Niagara Falls and St. Catharines, while Liberal Premier Kathleen Wynne has two stops in Toronto.

On the campaign trail Wednesday, Wynne said if Hudak wins the most seats on June 12 but falls short of a majority, she'll do what she can to make sure a minority government functions.

But she didn't have a clear answer when asked repeatedly whether she would be willing to team up with the NDP if a minority Tory government is short-lived.

Hudak called Wynne's comments that she would let the winning party form a government an "encouraging change" but questioned her motivation.

He suggested Wynne was concerned about a public uproar if she clung to power after losing the election.

A re-elected Liberal government would bring back the Ontario legislature within 20 days of the June 12 election and re-introduce the budget that triggered the vote, Wynne said Wednesday.

Two federal party leaders waded into the Ontario campaign Wednesday.

Liberal Party of Canada Leader Justin Trudeau laid into Hudak's plan to cut public sector jobs during a Wednesday evening rally in Ottawa with Premier Kathleen Wynne.

Meanwhile, national NDP Leader Tom Mulcair made his first foray into the Ontario election Wednesday night, headlining a fundraiser for the provincial party in Toronto.

So far, the leader of Her Majesty's Official Opposition in Ottawa has been absent — at least publicly — from the Ontario campaign.

The fundraiser with Horwath was a private event, closed to the media. The party wouldn't say whether Mulcair will be involved in any more campaigning in the week remaining before election day next Thursday.
