Threats

It is dirty.  There are currently 40,000 tonnes of high level radioactive waste at reactor sites in Canada.  This waste remains deadly for a million years – a threat to human health and the environment.   Canada’s stockpile of radioactive waste will double if  Canada's reactors are not permanently closed over the next 15 years  -- a nuclear nightmare for future generations.   Canada’s nuclear stations release radioactive pollutants into the air and the water of the Great Lakes.  Radioactivity can be absorbed by living things through air, water and food, and increases the risk of cancer.

It's dangerous.  Safe nuclear power is a myth. Human error, terrorist attack or technical failure could cause a meltdown at any of Ontario’s nuclear stations. A catastrophic radiation release could make large parts of Southern Ontario uninhabitable for thousands of years. As Ontario’s reactors get older, accidents become more likely.

It's expensive. Every nuclear plant in Canada has undergone massive cost over-runs and delays.   The high cost of nuclear power effectively bankrupted Ontario Hydro and every month Ontarians pay down the the nuclear industry's massive debt on their electricity bill.   Worse, there are still bills to be paid: Ontario Power Generation recently admitted that long-term management of radioactive waste would cost $18 billion.

It's unreliable.  While Ontario’s reactors were designed to operate for 40 years, Ontario Power Generation admitted in 2003 that even the best ones would need to be shut down or be rebuilt at high cost and risk after only 25-years.

It’s too slow.  It takes at least ten years to build a new nuclear reactor, and all past reactors have had long delays.   Green energy options are quicker to deploy  and over time add up to provide a  cumulative energy punch as big as any nuclear megaproject.

It undermines a clean energy future. A dollar can only be spent once and every dollar spent on nuclear is a dollar not available for green energy and conservation.
