An Ontario Liberal MPP has apologized to Tim Hudak for distributing flyers showing the PC leader laughing as a hospital explodes behind him.

Steven Del Duca's campaign team apparently used a Photoshopped image from Postmedia's Ishmael Daro that shows Hudak imposed over a still from the Batman movie, "The Dark Knight." The pamphlets were sent to households in Del Duca's Vaughan riding, just north of Toronto.

Liberal Leader Kathleen Wynne said Wednesday the image was "not acceptable."

A Tory staffer shared a photo of one flyer on Twitter and wondered if Grits were suggesting Hudak is a terrorist.

Deputy PC leader Christine Elliott also didn't take kindly to her leader being compared to The Joker.

She called the flyers a deliberate, "sickening" attack meant to scare voters into voting for Wynne.

Del Duca took to Twitter to apologize Wednesday morning, calling the pamphlets a "mistake."

With just 24 hours to go in the campaign, Liberals have ramped up their attack of Hudak's pledge to eliminate 100,000 public sector jobs in the first four years of a PC government. Hudak maintains his cuts won't impact healthcare.

Using some of her toughest language to date, Wynne warned Tuesday that a Hudak government could result in dire consequences for Ontarians.

"What he is proposing is dangerous for the people of this province, it's dangerous for children, it's dangerous for the people who are needing health care," she said.

Liberals have also accused the PCs of sneaky voter suppression tactics after 64 household in a southwestern Ontario riding received letters from Tories directing them to the wrong polling station.

Though the Tories say it was an honest mixup, Grits have filed a complaint with Elections Ontario.

Hudak, meanwhile, is accusing his rivals of throwing mud and doing his level best put people at ease about the notion of a PC government.

"The sun is still going to shine, cows will still give milk, the sky is still going to be blue. I know they're going really across the line to try to distort things," he said in Richmond Hill Tuesday.

"But you want to know what's going to be different come June 13 under the PC government? You're going to have hope again."

Polls suggest the Tories and Liberals are neck and neck heading into the vote Thursday.

  • UP NEXT: Federal Conservatives vs. Ontario Liberals

  • Ontario Liberal leader <a href="http://www.huffingtonpost.ca/news/kathleen-wynne/" target="_blank">Kathleen Wynne</a> has taken a number of shots at <a href="http://www.huffingtonpost.ca/news/stephen-harper/" target="_blank">Prime Minister Stephen Harper</a> and his federal Conservatives so far in her campaign. And some federal Tories are firing right back. <em>With files from The Canadian Press</em>

  • 'Stand Up' To Harper

    Wynne <a href="http://news.nationalpost.com/2014/05/04/kathleen-wynne-tells-harper-to-move-out-of-the-way-after-pm-calls-ontario-pension-plan-a-payroll-tax/" target="_blank">wasted no time</a> criticizing the Harper government in her first speech after announcing a provincial vote had been called for June 12. Wynne said the priorities of her government are increasingly at odds with Ottawa. "We need a premier who is willing to stand up to Stephen Harper," she said. "The federal government pours billions of dollars into the oilsands, but when it comes to the Ring of Fire, Stephen Harper has not acted."

  • Ontario Pension Plan? Meh.

    Just hours after the provincial election was called, Harper suggested Wynne's proposal for an Ontario Retirement Pension Plan won't be a hit at the polls. When asked if Wynne could win the election with the plan, the prime minister said <a href="http://www.huffingtonpost.ca/2014/05/02/ontario-pension-plan-stephen-harper_n_5255152.html" target="_blank">increasing taxes isn't the way to go.</a>

  • Wynne To Harper: 'Move Out Of The Way'

    Wynne then called Harper's comments about her pension plan "unusual" and told reporters she's <a href="http://www.huffingtonpost.ca/2014/05/03/kathleen-wynne-stephen-harper_n_5258030.html" target="_blank">not in the race to run against the prime minister.</a> "The first choice would have been to have an improvement and enhancement to the Canada Pension Plan, but the federal government is not interested in doing that," she said. "So quite frankly I think that if Prime Minister Harper isn't interested in partnering with us then he should move out of the way."

  • Say It Ain't So, Joe

    Finance Minister Joe Oliver joined the fray, <a href="http://www.huffingtonpost.ca/2014/05/03/kathleen-wynne-joe-oliver-ontario-election_n_5258700.html" target="_blank">ripping the budget Wynne tabled</a> a day before calling the election. The spending plan is, essentially, the platform on which Ontario Liberals are running. "This is the route to economic decline, not the route to economic growth or job creation," he told CBC Radio's The House. And Oliver made clear he's also <a href="http://www.huffingtonpost.ca/2014/05/03/kathleen-wynne-joe-oliver-ontario-election_n_5258700.html" target="_blank">no fan of Wynne's pension plan,</a> calling it a $3.5 billion tax on "workers and businesses" that will kill jobs in Ontario. "This isn't the time to do it," he said.

  • 'Nonsense'

    And Natural Resources Minister Greg Rickford <a href="http://www.huffingtonpost.ca/2014/05/03/kathleen-wynne-joe-oliver-ontario-election_n_5258700.html" target="_blank">told CBC News </a>that Wynne's comments about alleged Tory inaction on the Ring of Fire file were "nonsense."

  • Oh Really?

    Wynne didn't care much for Oliver weighing in on her budget. In fact, the Ontario Liberal leader <a href="http://www.cbc.ca/news/canada/toronto/ontario-votes-2014/kathleen-wynne-harper-taking-over-the-voice-of-tories-in-ontario-1.2630898" target="_blank">accused Harper</a> of "taking over the Conservative voice in the Ontario election."

  • Sorry (But Not Really)

    Oliver later denied to reporters he was trying to intrude on the Ontario election, but was careful to <a href="http://www.huffingtonpost.ca/2014/05/05/joe-oliver-ontario-pension-plan_n_5269500.html" target="_blank">repeat his earlier criticism about Wynne's pension proposal.</a> "It's not the time, in my opinion, to impose this type of tax when the Ontario economy is so fragile," he said.

  • Who Wants To Talk About Harper's Pension?

    Wynne then singled out Harper by saying his pension is about 10 times the maximum payout available under the CPP. "Stephen Harper when he retires is going to have about 10 times that amount in his pension," she said. "So the reality is that if he doesn't believe that the Canada Pension Plan should be enhanced, then he should move out of the way and let Ontario do its work."

  • And Then She Released This Tweet...

  • Tony GOES OFF

    Treasury Board President <a href="http://www.huffingtonpost.ca/news/tony-clement/" target="_blank">Tony Clement </a>then took the fight to Wynne during a <a href="http://www.huffingtonpost.ca/2014/05/06/ontario-election-2014-tony-clement-wynne_n_5277480.html" target="_blank">segment on CBC's "Power & Politics."</a> The former Ontario MPP didn't mince words, calling Wynne's pension plan proposal a "tax grab" meant to distract from various scandals. "She doesn't want to talk about the gas plants scandal, she doesn't want to talk about E-health scandal. She wants to divert attention from her government's terrible record on these things as well as terrible economic record," he said. "So, I'm not going to play into her campaign strategy, quite frankly."

  • Smirk-Gate?

    Wynne <a href="http://www.thestar.com/news/queenspark/2014/05/08/kathleen_wynne_says_stephen_harper_smirked_and_said_people_should_save_for_their_own_retirement.html" target="_blank">told The Toronto Star</a> that, in a private meeting in December, Harper "smirked' and told her people ought to be saving for their own retirement and not count on the government. “It was their fault and people need to pull themselves up by their bootstraps and they need to just save because there's lots of opportunities,” she recalled in the paper.

  • Not Quite, Harper Spokesperson Says

    Jason MacDonald, Harper's chief spokesperson, suggested to The Star that Wynne <a href="http://www.thestar.com/news/queenspark/2014/05/08/kathleen_wynne_says_stephen_harper_smirked_and_said_people_should_save_for_their_own_retirement.html" target="_blank">wasn't being entirely truthful</a> about her meeting with the prime minister. "Presumably she made the comments she made today to distract from her mismanagement of the Ontario economy and the fact that she can’t run on her party’s record," he said.

  • Don't Forget About Us

    In a speech delivered not far from Parliament Hill, Wynne accused Harper of <a href="http://www.huffingtonpost.ca/2014/05/08/ontario-election-2014-wynne-harper-ring-fire_n_5288618.html" target="_blank">neglecting Canada's largest province.</a> "Right now, on a number of important issues, the interests of the people of Ontario are at odds with the policies of Stephen Harper's government," she said. "In a very real way, the federal government is balancing its budget on the backs of Ontarians."

  • Clement Fires Back.. Again

    Clement didn't appreciate Wynne's digs at the prime minister and told reporters he wants Ontario PC Leader Tim Hudak to win the election. "[It's] a campaign technique to deflect attention from the disastrous record of the Ontario Liberal government, economic record as well as gas plants and shredding emails and 40 percent hikes in hydro bills," he <a href="http://www.huffingtonpost.ca/2014/05/08/ontario-election-2014-wynne-harper-ring-fire_n_5288618.html" target="_blank">told reporters.</a> "I personally want the election of Tim Hudak as premier of Ontario. I personally do, but we’ll work with anybody who forms the government, of course, in the national interest and the provincial interest."

  • No Surprises

    Wynne then shot back by saying federal Tories are "attacking" because they <a href="http://news.nationalpost.com/2014/05/09/federal-tories-fire-back-at-wynne-clement-attacks-ontario-liberals-disastrous-record-calls-for-partys-defeat/" target="_blank">don't share her government’s values.</a> "We know [Harper] doesn't like it because Tony Clement was sent out to attack today," she told a crowd in Kingston, Ont. "Not a surprise that Tony Clement and Tim Hudak would be on the same page, is it? Not a surprise at all."

  • Alberta Tory MP Weighs In

    Blake Richards, who represents the federal Alberta riding of Wild Rose, shared a story about an Ontario Liberal candidate's <a href="http://www.sunnewsnetwork.ca/archives/sunnews/politics/2014/05/20140512-214903.html" target="_blank">controversial Facebook posts.</a>

  • UP NEXT: 5 Ontario Liberal Scandals

  • An Uphill Climb?

    Kathleen Wynne is hoping Ontario voters can look past these five scandals when they cast their ballots on June 12. <em> (Information courtesy of The Canadian Press)</em>

  • Ornge

    Ontario's publicly funded air ambulance service has been under fire for almost two years over sky-high salaries, financial irregularities and corruption allegations. A legislative committee has been probing the service's complex structures and pay scales in detail, and opposition parties have been alleging wrongdoing with nearly every revelation. The auditor general has criticized the governing Liberals for failing to oversee Ornge, despite giving it $730 million over five years and allowing it to borrow another $300 million. The Liberals insist Ornge went rogue with a web of for-profit companies and questionable business deals, as well as exorbitant salaries and lavish expenses.

  • Cancelled Gas Plants

    Scandal has swirled around the government's decision to cancel the construction of two Toronto-area gas plants ahead of the 2011 election, in which the government then led by Dalton McGuinty was reduced to minority status. The cancellation costs have now been pegged at $1.1 billion, but opposition parties have accused the Liberals of actively trying to cover up that figure. Ontario's privacy commissioner has concluded that staff working for McGuinty and a former energy minister broke the law by deleting emails pertaining to the project. Ontario Provincial Police are also investigating the document deletions, seizing government computers at both Queen's Park and beyond.
