Progressive Conservatives are calling on Premier Wynne to come clean on the cost of the MarS real estate deal.
The Tories released documents last week they claim show the Liberals secretly signed off on a $317-million bailout for the Toronto real estate project.
Critic Vic Fedeli says Wynne should disclose all documents related to the deal before tomorrow's leaders' debate.
The Liberals, meantime, say the inspiration of PC leader Tim Hudak's platform comes directly from the extreme-right Republican movement in the U.S.
The Liberal have released documents of their own, claiming Hudak met with leading Republican and Tea Party strategists during his trip to Washington in April 2012.
They say part of the meeting included media training with a firm who's also worked with Minnesota Congresswoman Michelle Bachman.
New Democrats have released new ads in their campaign to end the scandals at Queen's Park.
The ad, entitled “I’m voting Andrea,” features a number of people who say they voted Liberal in the last election, but will be switching their vote to the NDP.
The NDP have also set up a website for other voters to comment on why they plan switch their vote.
