Nuclear reactors in Canada

Greenpeace fights nuclear power because it poses a serious threat to the environment and humanity. The expansion of nuclear power must be halted and nuclear plants shut down so that we can develop a clean energy future. That's why we are working to stop Darlington in Ontario and protect electricity consumers from a new round of nuclear debt.

The current provincial government wants to spend $36 billions to rebuild aging reactors and build new one at the Darlington nuclear station. Ontario can't afford to spend billions on nuclear power and not foster renewabile energy, which is our hope for long term growth. That’s why we say Don’t nuke green energy. This is the wrong path for Canada.

Every dollar governments and the nuclear industry spend repairing old reactors and building new ones reduces our chance to build Canada's future on sustainable energy.

How Greenpeace fights nuclear energy

  • Challenging industry claims: We produce material that shows the true costs and the threats of nuclear electricity, which the industry wants to hide.
  • Pressuring politicians: Through actions and interventions at hearings, we take on politicians and regulators to force them to tell the public the truth about nuclear costs and risks.
  • Informing the public: We reach out to Canadians through actions, activities and news events in an effort to inform them of the costs and threats of nuclear energy and of the real solutions to the climate crisis.

Greenpeace's "Don't Nuke Green Energy" campaign is working for energy systems that fight climate change and improve our economy. We want an Energy [R]evolution with clean, renewable energy — wind, water, solar and local generation — that will transform our economy for the better.

Our campaign exposes the subsidies and sweetheart deals for the nuclear industry that undermine the growth of green energy.
