TORONTO - Education Minister Liz Sandals says the province has reached a tentative agreement with the union representing Ontario's public high school teachers.

Sandals says the agreement resolves implementation concerns on issues such as sick leave, maternity leave, retirement gratuity, unpaid days and local bargaining.

Sandals says the details of the agreement will be shared with members of the Ontario Secondary School Teachers' Federation over the coming days.

Full details will be released once the union's approval process is complete, but until then a media blackout remains in place.

The Liberal government imposed contracts in January that froze the wages of most teachers.

The union agreed in late February to suspend its withdrawal of extracurricular activities -- sparked by the move to impose contracts.

Talks continue with the Elementary Teachers' Federation of Ontario which suspended its advice that members boycott voluntary activities late last month.
