Several Ontario First Nations indigenous groups are set to become owners of a new nuclear power plant after striking a commercial partnership with the federal and provincial governments.

Ottawa and Ontario are providing loan guarantees of CAD700m ($491m, €433m) to the seven Williams Treaties First Nations* northeast of Toronto that will turn into equity for one of the four small modular reactors (SMRs) that are being built at the Darlington nuclear site by Ontario Power Generation (OPG).

OPG is already building the first unit of the Darlington BWRX-300 SMR project. Darlington is being developed as a four-unit SMR site to provide low-carbon electricity and support growing demand in Ontario.
