MARKHAM, Ont. -- Ontario Premier Kathleen Wynne isn't ruling out teaming up with the New Democrats to form a government if the Progressive Conservatives win the most seats on June 12, but fall short of a majority.

The Liberal leader said her main focus now is working hard for the remainder of the campaign to ensure her party wins the most seats.

Once the voters decide, her party will "make that determination," she said Wednesday after visiting an elementary school in Markham, north of Toronto.

"I'm not ruling out anything except working as hard as I can over the next 16 days to make sure that we get to Queen's Park and we can implement our plan," she said.

Wynne said she's demonstrated that she can work in a minority parliament and promised to continue to do so if the Liberals fail to win a majority.

"So you need to look at what I've done over the past year and a bit, that's how I would function, but I am not going to pre-empt what the people of Ontario might decide on June 12."

Whatever the configuration of the next parliament will be, she'll bring forward her plan for the province and do everything in her power to make sure it gets implemented, Wynne said.

NDP Leader Andrea Horwath, who has called the Liberals corrupt, was tight-lipped on the subject.

"I'm going to wait until June 12, until the people of this province make a decision about what kind of government they want and regardless of what decision they make it'll be the right decision... and we'll deal with that outcome once it's upon us," she said.

The Progressive Conservatives say voters deserve to know if Wynne intends to form a coalition government if she loses the election.

"What is clear is that Kathleen Wynne is so desperate to cling to power that she will do absolutely anything to keep her job," they said in a news release.

Public opinion polls suggest it's a tight race between the Liberals and Conservatives, and there's a realistic possibility that Ontario will have another minority government.

In 1985, the provincial Liberals and NDP teamed up to replace the newly elected minority Tory government under then-leader Frank Miller. The New Democrats under Bob Rae signed an accord with Premier David Peterson's Liberal government, agreeing to support them for two years if the Liberals implemented some of their policies.
