Windsor-Tecumseh candidates are getting last minute campaigning in before Thursday’s byelection.

A poll released by Campaign Research Wednesday shows NDP candidate Percy Hatfield has 52 per cent support for Dwight Duncan’s old seat. The PC candidate, Robert De Verteuil and the Liberal candidate Jeewen Gill trail with 22 per cent and 16 per cent respectively.

Other candidates in the riding include Adam Wright for the Green party, Lee Watson for the Family Coalition, Dan Dominato for Libertarian and Andrew Brannan for the Freedom party.

The results of the fire provincial byelections won't change the fact Ontario has a minority Liberal government.

Other than Windsor-Tecumseh, votes are being held London, Ottawa and two Toronto ridings to replace five Liberals who quit this year, including former premier Dalton McGuinty.

Like all the party leaders, Premier Kathleen Wynne downplays expectations for the byelections, saying they are always challenging for governments.

The Progressive Conservatives hope people use the byelections to register protest votes against the Liberals for the $585 million spent to cancel two gas plants prior to the 2011 election.

Opposition Leader Tim Hudak says it's a chance for voters to look at the scandals and say they want a change in government.

NDP Leader Andrea Horwath says voters know the minority Liberal government's budget was full of New Democrat proposals such as cutting auto insurance rates.
