Canada’s Deadly Secret: Saskatchewan Uranium and the Global Nuclear System is a 2007 book by Jim Harding which chronicles the struggle over Saskatchewan’s uranium mining, and demonstrates the negative impacts on Aboriginal rights and environmental health, and the effect of free trade. Professor Harding argues that nuclear energy cannot mitigate global warming and that the "peaceful atom" does not exist. Helen Caldicott wrote the foreword to the book.
