“B.C. Hydro’s plan is to flood our farm and destroy it. My grandpa chased the BC Hydro people away when they asked him to sell the farm decades ago to make way for Site C. I look out every day and see the same view that my grandpa saw when he was here. That sort of thing is priceless.”

Site C Dam

Y2Y is working with partner organizations to stop the $8.75-billion Site C dam on British Columbia’s Peace River.

Y2Y is working with partner organizations to stop the $8.75-billion Site C dam on British Columbia’s Peace River. 


The British Columbia (B.C.) government has approved construction of a third dam, Site C, on the province’s scenic Peace River. Construction of the $8.75-billion dam and reservoir is expected to begin in 2015 and they will be operational in 2024. Site C will flood more than 62 miles (100 km) of wildlife-rich valley bottoms, including some of B.C.’s best farmland, and it will force families from their homes, and farmers and ranchers from their land.

Environmental Impact

Approval of the dam was made despite the conclusions of the Joint Federal-Provincial Review Panel, which examined Site C’s environmental impacts. It stated that the effects of Site C will be so significant that only an “unambiguous” need for power can justify the dam’s construction. It also said that BC Hydro had not fully demonstrated the need for more electricity.

The review panel noted that Site C will destroy wetlands that support migratory bird flocks and will have “significant adverse effects” on fish and fish habitat. Specifically, they said the dam threatens the survival of three distinct groups of mountain whitefish, bull trout and Arctic grayling.

Impact to the Yellowstone to Yukon Vision

Site C and its massive reservoir is situated in Y2Y’s Peace River Break (PRB) priority area and located at the narrowest point in the entire Yellowstone to Yukon region. From Y2Y’s perspective, the project jeopardizes key wildlife populations and threatens our vision.

Site C will form yet another barrier to wildlife movement in a region where industrial development is expanding so rapidly that it exceeds the pace of development in Alberta’s oil sands. And according to a Y2Y-commissioned expert report by biologist Dr. Clayton Apps, construction of Site C will threaten the future survival of several wildlife populations in the region. Read the full report.


Six court cases have been launched against federal and provincial governments to try to stop Site C. If the cases are successful the dam will not proceed.

  • Four Treaty 8 First Nations (Doig River, Prophet River, West Moberly and McLeod Lake bands) launched a Federal case and one against BC Hydro.
  • Alberta’s Mikisew Cree First Nation and Athabasca Chipewyan First Nation filed two lawsuits in Federal Court regarding Site C impacts on downstream ecosystems. 
  • Landowners in the Peace River region launched challenges in both B.C.’s Supreme Court and federal court.

Y2Y is the leading voice for raising awareness for the impacts of the dam on the region and wildlife.

Among other initiatives we have:

  • Commissioned a report and presented to the Joint Review Panel a scientific assessment of the impacts of Site C on wildlife habitat and movement;
  • Successfully nominated the Peace River to be declared B.C.'s Most Endangered river by the B.C. Outdoor Recreation Council;
  • Funded and supported our partners, who are also raising awareness to stop the dam.

We continue to collaborate with First Nations, environmental groups, outfitters, farmers, researchers, Peace Valley landowners and other concerned individuals to challenge construction of the Site C Dam. Currently we are actively supporting many of the legal cases challenging the dam.
