TORONTO -- More elementary school teachers will stage one-day strikes today

They started yesterday in the Stratford and Timmins area and spread today to Niagara and Keewatin-Patricia in northwestern Ontario.

Elementary teachers in Ottawa-Carleton, Lakehead in Thunder Bay and Hastings-Prince Edward will walk out on Wednesday.

Teachers at three other school boards -- York Region, Trillium Lakelands and Renfrew -- plan to participate in the rotating job action on Thursday.

Premier Dalton McGuinty said Monday that the teachers are striking over money.

But their union maintains it is trying to roll back a new anti-strike law that gives Queen`s Park the power to impose a new collective agreement.

McGuinty also said the one-day strikes by elementary teachers are a "small price to pay" to protect gains in education.

He said his government won't intervene in the rotating strikes, but it's a small sacrifice to protect full-day kindergarten and smaller class sizes.
