The Williams Treaties First Nations committed CAD700 million (USD492 million) to Ontario Power Generation's Darlington New Nuclear Project, marking a material Indigenous investment in Canada's nuclear sector. The investment supports the construction of a BWRX-300 small modular reactor at the Darlington nuclear site in Ontario, with a capacity of 300 MWe. The project benefits from CAD1.2 billion in loan guarantees from federal and provincial programs, including support from the Canada Infrastructure Bank and the Ontario Financing Authority. Expected to commence operations in the early 2030s, the BWRX-300 reactor will be the first of its kind in Canada, enhancing grid stability and clean energy supply. The deal underscores the growing role of Indigenous communities in large-scale energy infrastructure while advancing Ontario's decarbonization goals. Regulatory approvals and Indigenous consultation processes are ongoing, with financing structured to ensure long-term project viability.
