After several decades of environmental reviews and scientific studies, the federal and provincial governments undertook a $400 million cleanup of the site which saw the industrial contaminants in the estuary contained through a stabilization and solidification process. Site remediation was carried out by Nova Scotia Lands Incorporated and Harbourside Commercial Park Inc., a Crown corporation formed to redevelop the site as a commercial and industrial estate. The cleanup was completed in 2013 with the opening of Harbourside Commercial Park and Open Hearth Park, which are situated on the site of the former Sydney Steel Corporation.
