Nuclear power is one of the best ways to meet the constant electricity demands of Ontario reliably, cost effectively, and without the environmental impact of greenhouse gas and carbon emissions.
Today, approximately 60% of Ontario’s power needs are met by nuclear.
Discover how this powerful energy source has become an important tool in fighting climate change both locally and globally, and continues to be an important part of Ontario Power Generation’s generating mix.

Nuclear powered potential
Nuclear power remains one of the most misunderstood sources of energy available. As the world faces the reality of a rapidly changing climate, nuclear power is essential in the fight against climate change because of its ability to produce large amounts of low-cost power safely, reliably, and virtually without carbon emissions. Its extensive use in Ontario is one of the reasons why the province remains one of the lowest carbon intensive jurisdictions in the world.
By the numbers:
According to the Canadian Nuclear Association in Canada alone, nuclear energy:
Helps avoid 80 million tonnes of CO2 emissions per year
That’s roughly the equivalent of taking 15 million passenger vehicles off the road
That’s because nuclear power doesn’t burn fuel to make power, which produces greenhouse gas and carbon emissions.
Despite what some believe, renewable energy sources like wind and solar alone aren’t enough to reliably meet the growing needs of Ontario due to their unpredictability (calm windless nights or short cloudy winter days).
Nuclear allows for consistent 24/7/365 baseload power generation that will continue to play an important role in Ontario’s energy mix for decades to come.
In 2020, we launched our Climate Change Plan and made a commitment to being a net-zero company by 2040, and create a net-zero economy by 2050. And while these goals are ambitious, they’re not enough on their own. That's where the Climate Challengers come in. Meet the people who have made it their mission to change the fate of our futures for the better.

Did you know? No member of the public has ever been harmed as a result of a radiation emission from our nuclear power plants or nuclear by-product storage facilities.
Did you know? You receive 200 times more radiation exposure during a cross-Canada flight as you do living next to one of our stations in a full year.
Did you know? OPG’s Nuclear Power is used for more than just generating electricity. It’s also used to power lifesaving medical imaging technology and sterilize medical equipment.
Our commitment to your safety
OPG’s number one priority is to ensure your safety. That’s why our nuclear stations are designed with multiple safety systems and are staffed by station personnel who are extremely well trained.
In the more than five decades of our nuclear operations, no member of the public has ever been harmed as a result of a radiation emission from a nuclear power plant or management of nuclear by-products through their entire lifecycle. We continuously measure radiation exposure at the perimeter of our stations to ensure our communities are safe and healthy.
Our commitment to safe storage
Stewardship of nuclear by-products is an often controversial topic, but it’s an important one. Protecting the health of our communities and the environment today and in the future is a key part of OPG's Nuclear Sustainability Services division's nuclear by-product management strategy.
Unlike other energy sources like coal where its waste is released through emissions that impact the environment and air quality, nuclear by-products are small in volume, safely handled and stored. Some by-products are clean, recyclable and valuable – from copper and steel, heavy water to isotopes used for life saving medical use.
OPG has successfully transported and stored nuclear by-products for decades, and we are committed to protecting future generations through well thought out and scientifically- and expert-validated long-term solutions. That’s our commitment to you.
