Ontario’s Nuclear Ambition: A Strategic Move or a Risky Gamble?
With a significant financial commitment, the Canadian government has placed its bets on a new direction for Ontario’s energy future. The inception of four small modular reactors (SMRs) at the Darlington site, backed by a $2 billion federal investment through the Canada Growth Fund and an additional $1 billion from the provincial Building Ontario Fund, marks a pivotal moment in the nation’s clean-power strategy. This initiative aligns with Prime Minister Carney’s climate-industrial agenda, yet it raises questions about its long-term viability and impact on Canada’s energy landscape.
Historically, Ontario has been a leader in nuclear technology, primarily through its development and operation of CANDU reactors, a cornerstone of the province’s power supply and job creation. However, the decision to construct the first GE Hitachi small modular reactor represents a shift from this legacy. While some view this as a forward-thinking move, others caution that it may lead to unforeseen challenges.
The Darlington site, currently Ontario’s largest employer, supports about 15,000 jobs. The ongoing refurbishment of existing reactors promises continued employment through 2065, but the addition of SMRs introduces new complexities. The GE Hitachi BWRX-300, unlike the familiar CANDU systems, relies on enriched uranium and U.S. supply chains, requiring Ontario’s workforce to adapt to a new technology under evolving regulatory frameworks.
Project data from Bent Flyvbjerg’s extensive megaproject database indicates that nuclear builds are notorious for cost and schedule overruns. Reference-class forecasting suggests that Darlington’s first SMR, initially estimated at around $6 billion, could exceed $18 billion and face significant delays. These projections highlight the economic risks associated with nuclear projects, which often face extended timelines and increased financing costs.
Ontario is already investing heavily in making its nuclear fleet compatible with a modern grid. Yet, the inherent inflexibility of nuclear energy leads to reliance on fossil fuel plants for balance, ultimately increasing emissions. Despite the availability of cheaper renewable options, the current path prioritizes nuclear, potentially resulting in higher electricity costs and reduced energy independence.
The geopolitical implications of this decision also warrant consideration. The reliance on an American-designed reactor introduces dependencies on U.S. regulations and fuel supply, which could be subject to political fluctuations. This dependency contrasts starkly with Ontario’s historical pursuit of energy sovereignty.
At the heart of the project is AtkinsRealis, formerly SNC-Lavalin, which plays a significant role as an engineering partner. While the company has moved past previous scandals, its involvement in the SMR initiative, particularly without a leading technological role, introduces potential political risks.
Ontario’s energy strategy currently emphasizes nuclear, providing more than half of the province’s electricity. However, a shift towards flexible and renewable energy sources could offer a more sustainable path. As it stands, the focus on SMRs may hinder the expansion of renewable technologies, despite the potential for a more efficient and cleaner energy grid.
Looking ahead, the trajectory of this initiative is uncertain. While the intention is to decarbonize and enhance industrial capabilities, the reliance on imported technology and the high costs associated with nuclear energy could limit its success. The decision to pursue this path may have long-lasting implications for Ontario’s energy sector and its economic resilience.
