Ontario has embarked on building a new nuclear reactor at Darlington. We explore the plan with Prof. Jatin Nathwani, Executive Director of the Waterloo Institute for Sustainable Energy; and hear why environmentalists are so divided on nuclear power. We're joined by Environmental Defence Director Keith Brooks; and Dr. Chris Keefer, President of Canadians for Nuclear Energy and Director of Doctors for Nuclear Energy. CORRECTION: On the original broadcast, Susan O'Donnell was misidentified. She is a member of the Coalition for Responsible Energy Development in New Brunswick and an Adjunct Research Professor at St. Thomas University.
