Ontario Premier Dalton McGuinty has announced the byelection for Kitchener-Waterloo will be held on Thursday, September 6th.

There will also be a byelection held that day in Vaughan.

The votes will be held to fill the two seats left vacant by Conservative Elizabeth Witmer and Liberal Greg Sorbara.

Sorbara resigned last week to devote himself to running the Liberals’ election campaign, while Witmer was given a plum appointment by McGuinty to head the Workplace Safety and Insurance Board.

McGuinty toured a school in Maple just before making the announcement, and says for him making sure there’s labour peace in schools is the key issue in the byelections.

The premier also says calling the byelections does not mean he has ruled out calling the legislature back in an emergency session this month to impose a new contract on Ontario teachers.

McGuinty admits governments always have a difficult time winning byelections, but says the Liberals are the only party with a plan to secure a public sector wage freeze to eliminate the deficit.
