“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. 


In September 2015, the British Columbia (B.C.) government began logging in preparation for construction of a third dam, Site C, on the province’s scenic Peace River. If completed, Site C will flood more than 62 miles (100 km) of wildlife-rich valley bottom, including some of B.C.’s best farmland, and will force families from their homes, and farmers and ranchers from their land. 

The project’s environmental assessment concluded the dam would “cause significant adverse effects on fish and fish habitat…birds and bats…rare plants, and sensitive ecosystems” and “significantly affect the current use of land and resources for traditional purposes by Aboriginal peoples.” The dam is not a done deal and could be stopped by any of several active court cases.

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.


The movement to stop Site C is growing every day. Of particular significance is the case before the Federal Court of Appeal, brought by two Treaty 8 First Nations (Prophet River, West Moberly bands). This case has the power to stop the dam; a ruling is expected in late 2016 or early 2017.

Y2Y is the leading voice for raising awareness for the ecological 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, including active support for the Treaty 8 First Nations’ legal cases.

Site C to Undergo Joint Environmental Assessment

Site C will now go through a harmonized environmental assessment, reviewed by a joint panel. Both federal Minister of the Environment Peter Kent and B.C. Minister of the Environment Terry Lake believe that by combining the provincial and federal environmental assessment, they will avoid unnecessary duplication and delays.

Site C, Yes or No? Government Never Asked Locals

BC Hydro Corp. never appears to have outright asked Peace River region residents whether that project should go ahead during a year-long, $8-million public consultation process, which some participants have accused of being biased.
