Ms. Pupatello and Ms. Wynne emerged as the front runners early in the race. But Ms. Pupatello’s insistence on getting a seat before recalling the legislature put her at odds with many of her rivals. She retired from provincial politics in 2011 after 16 years as an MPP. Other contenders were anxious to re-open the legislature, which has been prorogued since mid-October.
The fact that Ms. Wynne has a seat in the legislature, and her policies focusing on eliminating the deficit while leaving nobody behind, played a role in the third and fourth place finishers endorsing her.
“I’m trying to send a signal that we want to get the house back as soon as possible,” Mr. Sousa told reporters. “We’re in a minority situation. I believe the public is looking for leadership on that score.”
Mr. Kennedy told reporters that Ms. Wynne’s desire to help the vulnerable and restore labour peace with the province’s teachers resonated with him.
“I was trying to win right up to half an hour before the [second ballot] vote was announced,” he said. “I realized that my path was pretty much in jeopardy.”
Mr. Kennedy, a former MPP and cabinet minister, said he has not yet decided whether to run in the next election, at which point Ms. Wynne leaned over and said, “if you want to know whether we have a spot in cabinet, yeah we do.”
She said she is delighted with the endorsements of three of her rivals, including Eric Hoskins.
“We’re going to form a great government,” she said.
Ms. Pupatello won the support of 39.4 per cent of delegates on the second ballot, giving her a three percentage point lead over Ms. Wynne.
Ms. Pupatello picked up an additional 218 votes, leaving her with 817. Ms. Wynne added another 153, bringing her tally to 750.
Mr. Kennedy trailed a distant third with 281 votes, Mr. Sousa with 203 and Harinder Takhar, who pledged his support to Ms. Pupatello after the first ballot, took just 18.
The two front runners each picked up the support of a lower-placed candidate minutes after finishing a hair’s breadth apart in the first round of voting.
Results of the first ballot had Ms. Pupatello with 599 votes, just two ahead of Ms. Wynne, with 597.
As soon as the first ballot results were announced, supporters of the remaining candidates began chanting “We want Eric!” Mr. Hoskins and advisors huddled in his booth, as delegates gathered on the convention floor below, shouting his name.
Health Minister Deb Matthews, one of Ms. Wynne’s campaign co-chairs, was spotted in his booth. Shortly after, former premier David Peterson, standing near Mr. Hoskins, turned to give Ms. Wynne what appeared to be a thumbs-up. Mr. Hoskins, however, kept everyone guessing by walking halfway across the convention floor before turning around and leading his delegates to Ms. Wynne. She walked halfway down the staircase leading to her booth and the pair embraced.
Just minutes later, Mr. Takhar took everyone by surprise by crossing over to Ms. Pupatello, even after his own staff insisted he wasn’t going anywhere. His change of mind came too late to remove his name from the second ballot.
Party insiders said Mr. Takhar’s sudden move was motivated by Ms. Wynne’s “momentum changing” speech. Many speculated that he had cut a deal with Ms. Pupatello, who was anxious to regain a wider lead over her chief rival.
“People have their own motivations,” said one of Ms. Wynne’s supporters.
Ms. Pupatello denied to reporters that she offered anything to Mr. Takhar in return for his support.
Mr. Takhar, for his part, said it was Ms. Pupatello’s focus on jobs and the economy that lead him to endorse her.
The convention’s more than 2,000 delegates are made up mostly of representatives elected by party members in each of the province’s 107 ridings, plus 419 party brass.
Outside, thousands of protesters, most of them teachers and public-sector union members, protested Mr. McGuinty’s move to impose contracts on teachers earlier this month.
And after Ms. Wynne’s victory, the opposition was quick to warn that the road ahead would be difficult.
In a statement, PC leader Tim Hudak said he looked forward to meeting with Ms. Wynne on Monday to discuss eliminating the province’s deficit.
New Democratic Party Leader Andrea Horwath said in a statement she looks forward to Ms. Wynne recalling the legislature without delay.
“Now, more than ever it’s time to roll up our sleeves and get to work on the challenges facing Ontario families,” she said.
