They are also far too slow. We understand that these new nuclear reactors would not come online until 2040 2048. That means more than 20 years of construction, cost overruns, and continued reliance on polluting gas. By contrast, new wind and solar projects can be built in 6 months 2 years, reducing emissions and lowering bills quickly. OPG is considering purchasing American-designed reactors from GE-Hitachi or Westinghouse. These reactors would require Ontario to import enriched uranium from the United States to fuel them. Does that seem like a good idea given the current political ...

From: J Houston Sent Date: Thu May 7 13:16:44 2026 To: Ontario Region / Region d'Ontario (IAAC/AEIC) CC: Subject: Impact of New Nuclear Power Plants To Whom It may concern, I would like to voice my opposition to the proposed new reactors to be installed in Ontario. Nothing about this plan makes sense to me. Firstly as an OPG customer this will adversely affect my hydro rates. Why has this plan been given priority over alternative energy, an option that would be up and running in half the time at 1/4 of the cost to ratepayers. Then there is the environmental factor. We have the issue of shipping the waste to a largely unwilling host on a highway that has already been deemed unsafe for public use due to the present load of transport traffic and the inadequacies of the highway to handle it. I would ask the government to at least consider the options to this expensive risky option. James Houston <personal information removed>

The most disheartening sentences in this document occur in Section 2.8.3 Alternatives to the project: IAAC will rely on the proponent’s Initial Project Description demonstrating that there are no alternatives to the project that are technically and economically feasible to meet the need for the project and achieve its purpose. The selection of electricity generation technologies and the broader energy supply mix in Ontario are matters determined through provincial energy planning and policy processes, including Ontario’s Integrated Energy Plan. It will not reassess provincial energy policy or determine the appropriate electricity generation mix for the province. On this basis, the information provided in the Initial Project Description is considered sufficient to address alternatives to the project for the purposes of these Integrated Guidelines, and no additional information is required.

I live in Northumberland County and am surprised by the number of people I talk to who haven't heard about this megaproject, notwithstanding all the OPG and government publicity . One reason could be residents are not aware of the tiny hamlet of Wesleyville, nor the history 50 years ago of an abandoned gas plant that ultimately wasn't needed. Instead of Wesleyville, what should the proponent or the IAAC call this project? Port Hope? The biggest nuclear power plant in the world will impact at least the 50 km radius of its emergency preparation zone. Anyone who knows this area will know the impacts of this project, should it be approved and actually proceed, will be profound throughout Northumberland County and beyond. The factors highlighted in OPG's promotional material mention most of them. Therefore the host community, which is more than merely a label, should be at least Northumberland County.

In the attached document It is identified that the Federal government has an obligation to take all risks into account through the Assessment Act. I have illustrated 19 examples that the current Ontario Government is not acting in the Public Interest. The proposed Nuclear plant application indicates there is no alternative to this project, which is false. When coupled with the 19 items of concern this government has shown these statements cannot be taken seriously as "truth" and the Assessment Act needs to be complied with, that is, an assessment of the renewable energy sources must be considered as part of the Assessment.

I am deeply concerned about Ontario Power Generation’s proposed Wesleyville Project nuclear power plant, but at this time, I will focus only on describing my concerns about the Draft Public Participation Plan. The Draft Public Participation Plan states that public participation “is meaningful” (page 6), but it does not define what meaningful participation might be. Does “meaningful” participation mean only that community members are free to say what they want and that they are provided with opportunities for doing so? Or does it mean that the concerns of community members will be considered by the IAAC and the Government of Canada and used to decide whether the Wesleyville Project goes ahead? The Draft Public Participation Plan must define what meaningful participation is in order to be a “meaningful” document.

Thank you for the opportunity to comment on the draft Integrated Tailored Impact Statement Guidelines for Ontario Power Generation’s New Nuclear Project at Wesleyville. I am concerned that the Guidelines do not provide a cost comparison between nuclear power generation and other options for power generation, including estimates for the lifelong stewardship of the power generation waste products. For reference, the World Nuclear Industry Status Report 2025 (https://www.worldnuclearreport.org/IMG/pdf/wnisr2025-v2.pdf), states: “Two recent authoritative, comparative assessments of the Levelized Costs of Energy (LCOE), i.e., the costs per kilowatt-hour over the lifetime of a facility, show a clear advantage of solar and wind power generation over traditional competitors.

The project description assumes the only alternative that will be considered is a nuclear plant and nuclear technologies yet to be determined. Does this mean that no other types of generation will be considered? If this is the case, I am immediately very disappointed with the IA process. (We have renewable technologies available, less expensive, faster to build, will begin reducing GHG emissions much sooner and don't leave a legacy of waste that will need to be safely stored for thousands of years.) It is not clear to a person not familiar with all the names for steps in your process how long these various phases may last (weeks, months, years?) It seems that in Phase 1 and 2, a lot of time is spent educating people about the IAAC/CNSC process which is definitely important. But what efforts will be made to educate surrounding communities about the project itself over it's full lifecycle (100+ years by the time decomm and ...

Since the potential adverse effects of nuclear can be mitigated by considering alternatives (solar, wind) it is hard for me to understand how the impact assessment can be conducted in a 'nuclear echo chamber'. The costs of nuclear - both from an economic and health perspective - are too high. Solar and/or wind generation (with storage) will cost Ontarians less and solar and/or wind will cost fewer lives. Having spent the day reading on the economics of nuclear vs. alternatives, and the health impacts of nuclear vs. alternatives, it is clear to me why OPG does not want to be required to justify nuclear vs. alternatives. The only benefits of nuclear seem to be: it takes less space, and it will provide jobs, and the waste is small in volume. Balanced against much higher cost, more deaths and illnesses, and the absence of a storage solution for waste that will be deadly for 1000s of years - I can see why OPG doesn't WANT to have to assess nuclear vs. ...

This project is too costly, too risky and too short sighted. The world's largest nuclear plant does not need to be built. And certainly not in our community, where so many are concerned about the inevitable risks. There are environmentally better options - better for the land, for the water, for the wildlife and for the surrounding communities. By the time this plant is built, nuclear will be irrelevant. Why not think to the future? Why not look to other nations who are creating green energy and follow their lead? I am disappointed and disheartened by the lack of foresight and planning. The damage done will be irreversible. We need our land to remain fertile, our lakes clean and our communities safe. As many have pointed out, young families will leave. Communities will be devastated. We urge you to reconsider and think to a brighter, smarter, cleaner future.

The Draft Integrated Tailored Impact Statement Guidelines specify that the “IAAC will rely on the proponent’s Initial Project Description demonstrating that there are no alternatives to the project that are technically and economically feasible to meet the need for the project and achieve its ...

We already have some solar and wind power which could and should be used as they do in Europe. We need to invest much more heavily in this renewable resource. Prior to the approval of this project, there should be a full environmental assessment that details disclosure of the total land footprint not just the reactor site, water sourcing and discharge, agricultural and environmental impacts, independent studies of the hydrogeological assessments and economic impact on agriculture vs energy jobs. We need to rethink nuclear power as the way to go for the entire planet not just our local corner of the globe.

As an organization grounded in the Model of Health and Wellbeing and the social determinants of health, CHCN values the direction the Guidelines take in expanding the impact assessment beyond biophysical effects to include the conditions that shape population health, equity, and wellbeing.

I am against this proposal for many reasons. First, I live in that area and am very aware of how good farmland is at risk here. Ontario loses 319 acres of good farmland A DAY, and once it's gone, it's gone. I am also very concerned about how this giant facility will impact nearby wildlife habitats and wetlands, and how much water it will use up. Our local water systems are often taxed by multiple months of drought, wells go dry, Baltimore community water system is suffering, farmers often don’t have enough ground water for their crops and livestock, and we have water use restrictions for months. We had a 6 month drought in 2017 and last year the drought lasted months. A nuclear power plant and its construction, cooling pools, and the electricity generation itself will take enormous amounts of water 24/7/365. We do not have enough water here for our agriculture, and existing homes and businesses so there certainly is not enough for the ...

To allow the construction of the world's largest nuclear power plant just over an hour east of Toronto at the proposed Wesleyville site is to place the most vulnerable in our community--children, animals, and the diverse ecosystem native to the Great Lakes Watershed--in perpetual, existential danger. The site itself would pose an ongoing, chronic risk to all life, as a nuclear power plant of such epic proportions ("the world's largest") is necessarily a threat to both national security (as a potential military target), and ground zero for conceivable, watershed-wide catastrophic environmental contamination. As the Great Lakes watershed is the largest surface freshwater system on Earth and is entirely connected, such devastation would have local, provincial, national, and global consequences.
