HAMILTON, Ont. - Unionized employees at U.S. Steel Canada's plant in Hamilton have ratified a collective agreement that the company says sends a positive message to its suppliers and customers during a court-supervised restructuring.

The agreement covers about 600 employees represented by the United Steelworkers union.

USW Local 1005 reached a tentative agreement with the company last week. It says the contract was accepted by 86 per cent of the votes cast, with 77 per cent of the membership represented.

The contract comes as the Canadian arm of Pittsburgh-based U.S. Steel operates under court protection while the company attempts to reach a compromise with its creditors.

The agreement runs until the end of March 2017, essentially extending terms of a labour agreement that expired on Oct. 15.

U.S. Steel Canada -- which owns the former Stelco operations -- employs about 2,000 people at the Hamilton Works in Hamilton and Lake Erie Works in Nanticoke, Ont.
