TORONTO - The New Democrats say anger over Ontario's low minimum wage and the pay hike politicians gave themselves before Christmas is going to hurt the Liberals in Thursday's three byelections.

Voters in Burlington, York-South Weston and Markham all go to the polls Thursday to elect new representatives.

New Democrat Cheri DiNovo says voters are upset politicians are now being paid 25 per cent more when minimum wage recently went up by just 25 cents.

Premier Dalton McGuinty wouldn't speculate on how his party will fare in the byelections, but says the minimum wage debate hasn't hurt the Liberals.

He says his government has increased minimum wage steadily and will continue to do so.

Political analysts say if the Liberals lose any seats Thursday, it could spell trouble for the government in October's provincewide vote.
