A tentative agreement has been reached to avert a strike by school bus drivers in central Ontario that was due to begin today.

Unifor says the agreement covers drivers with First Student Canada in the Owen Sound-Wiarton and Port Elgin-Kincardine areas.

Debbie Montgomery, the president of Local 4268, says the union achieved improved wages and working conditions "despite a difficult round of bargaining."

However, the details of the new contract will stay under wraps until members vote on it in the coming days.

Unifor had issued a strike notice last Friday.
