Ontario Power Generation Inc. (OPG) is proposing to redevelop three hydroelectric generating stations located on the Upper Mattagami River: Wawaitin and Sandy Falls generating stations located within the City of Timmins and Lower Sturgeon Generating Station located north of Timmins (The Proposed Undertaking).

The project is subject to the requirements of OPG's Class Environmental Assessment for Modifications to Hydroelectric Facilities under the Ontario Environmental Assessment Act. In addition, a number of environmental permits and approvals may be required including approvals from the Ministry of Environment and the Ministry of Natural Resources.

OPG is committed to an open and transparent consultation process with the respective First Nations, government agencies, the public and other interested stakeholders that may be potentially impacted by the proposed project through out the Class EA Process. Input and comments have been considered and included in the preparation of the Environmental Assessment Report. Two Public Open Houses were held in Timmins at key stages of the process to allow the parties the opportunity to speak directly with representatives of OPG and its environmental consulting team.

OPG has recently completed its environmental reports and is issuing its Notice of Completion and 30 day Public Review period. The Notice can be found on the Notice/Decision page. The environmental reports can be found on the Supporting Documents page.
