On November 7, 2025, the provincial government proposed a consolidation of Ontario’s 36 conservation authorities into 7 large regional authorities. Under this proposal, a new Northeastern Ontario Regional Conservation Authority would be created by merging four existing conservation authorities — Nickel District, North Bay-Mattawa, and Sault Ste. Marie. This new regional conservation authority would span a large geographic area forming a single fragmented organization stretching from Sault Ste. Marie north to Timmins and southeast to Mattawa and include 19 municipalities.

On November 27, 2025, the Province of Ontario passed Bill 68 created the Ontario Provincial Conservation Agency to oversee conservation authorities and transition to a regional watershed based framework for conservation authorities in Ontario.

On October 31, 2025, the Ontario Ministry of Environment Conservation and Parks announced plans to create a provincial board-governed agency, the Ontario Provincial Conservation Agency, to provide leadership, governance, and strategic direction to Conservation Authorities (CAs).

During the upcoming transitional period, the MRCA will continue to operate without disruption and continue to work toward our mission of leading the conservation and protection of the Mattagami Watershed. We remain committed to watershed protection at the local level.
