Innovative equity investment in the Darlington New Nuclear Project
On October 23, 2025, Ontario Power Generation (“OPG”) President and CEO, Nicolle Butcher, the Premier of Ontario and the Prime Minister of Canada announced that OPG entered into equity commitment agreements with Canada Growth Fund Inc. (“CGF”) and Building Ontario Fund (“BOF”), pursuant to which CGF and BOF will make equity investments in the Darlington New Nuclear Project (the “DNNP”). Under these agreements, CGF and BOF committed to invest up to C$2 billion and C$1 billion, respectively, each taking minority ownership positions in a special purpose vehicle that will carry out the DNNP.
The DNNP, which will be majority owned and will be operated by OPG, will see the construction of four grid-scale commercial SMRs — a first among G7 nations — that, when completed, are expected to deliver up to 1,200 MW of reliable, affordable, and low-carbon electricity, enough to power 1.2 million homes.
OPG expects to complete construction of SMR 1 by the end of the decade and connect it to the grid by the end of 2030. Construction on SMRs 2-4 is expected to be completed in the mid-2030s.
This transaction helps OPG de-risk the construction and operation of the first SMRs and paves the way to spur private sector and Indigenous investment in the DNNP over time.

OPG is a climate change leader and the largest, most diverse electricity generator in the province of Ontario.
CGF is a C$15 billion arm's-length investment vehicle designed to attract private capital to build Canada's clean economy. It uses investment instruments that absorb certain risks to catalyze private investment in low-carbon projects, technologies, businesses, and supply chains.
BOF is a board-governed Crown agency with a mandate to catalyze investment in revenue-generating infrastructure projects across Ontario. Backed by $8 billion in funding from the province, BOF supports transformative projects in five priority sectors: affordable and student housing, long-term care, energy, transportation, and municipal and community infrastructure.
