At an estimated $7.9 billion and growing, the proposed Site C Dam on the beautiful Peace River in northeastern B.C. has been criticized for spiralling costs, questions about whether the electricity it would produce is even needed, and concerns about the environmental and social impacts of flooding thousands of hectares of prime farmland, irreplaceable cultural sites and wildlife habitat.
