TORONTO -- The final full day of campaigning for Ontario's 41st general provincial election wrapped up with a deluge of last-minute mudslinging.
Accusations of sign tampering, voter suppression and attack literature were traded between the perceived frontrunners, the Ontario Liberals and Ontario Progressive Conservatives, after a long, tough campaign.
Polls will be open across the province Thursday between 9 a.m. and 9 p.m.
Elections Ontario has reported that turnout at advance polls was lower than in the 2011 general election.
Wynne was at a Toronto school Wednesday morning where she said she has an obligation to "contrast" her position with that of the opposition leaders, PC Tim Hudak and NDP Andrea Horwath.
"(On Thursday) we will choose one of two futures," she said. "Tim Hudak's future in which tens of thousands of people -- our neighbours, our friends, our family members are fired -- and ... health and education are put at risk. Or a future in which we create jobs and we nurture growth."
In Mississauga, PC Leader Tim Hudak accused Wynne of running a negative campaign by falsely claiming that the Tory plan would hurt children.
"When you go that far, when you go over the top that much just to hang on to your job, it's time to pack it in -- you're no longer there for the public interest, you are there for yourself," Hudak said.
A Liberal campaign flyer depicting Hudak as a Dark Knight villain walking away laughing from an exploding hospital was circulated in the riding of Vaughan.
Local Liberal candidate Steven Del Duca apologized on Twitter Wednesday after the Tories complained about the image.
"Please accept my apology. The flyer was a mistake for which I am sorry," Del Duca said in a tweet.
PC campaign manager Ian Robertson wrote a letter to Liberal campaign co-chairs David Herle and Deb Matthews demanding a public apology from them, Wynne and Del Duca.
"We are incredibly disturbed by a piece of literature being distributed by Steven Del Duca, the candidate for Vaughan. The piece depicts Tim Hudak laughing and walking away from a hospital that has just been blown up," Robertson said in the letter. "This piece of literature superimposes Tim Hudak into a horrifying scene from the movie the Dark Knight. The character, who you have depicted Tim as, is the villain from the film, a murdering terrorist."
Asked about the flyer Wednesday, Wynne told reporters it was unacceptable and insisted she has had nothing to do with the negative advertising campaigns launched by unions against Hudak.
Meanwhile, the Ontario Tories sent letters to potential voters that misdirected them to the wrong polling stations, the Liberals revealed.
"We sent out letters to the people that we hope are going to vote for the PC party to tell them what our plan is all about and to encourage them to go out and vote," Hudak said. "Sometimes, the mistakes are made because we did not have the right information and our candidates have apologized for that clerical error."
