TORONTO -- The union representing Ontario's high school teachers has reached a tentative deal with a school board north of Toronto.

The agreement between the Ontario Secondary School Teachers' Federation (OSSTF) and the York Region District School Board was reached just before 5 a.m. Saturday.

Board spokesman Licinio Miguelo says details in the contract will likely be sent to Ontario Education Minister Laurel Broten on Monday.

Miguelo says the board and the union have been in negotiations since early June.

Media reports say a deal has also been reached between the union and the Upper Grand District School Board in Guelph.

Earlier this week, the OSSTF advised its 60,000 members to begin a series of "strike actions" such as skipping staff meetings and not communicating with parents outside of school hours.

The province is facing a $14.8-billion deficit and has passed legislation freezing teachers' wages and taking away their right to strike.
