Is hydroelectric a pathway to decarbonization?
Watch our video to understand how hydroelectricity is greenwashed by Ontario Power Generation as “clean” and “non-emitting” when there are hundreds of independent third-party studies to the contrary. Read our full submission here!

2023 Annual Acquisition Report – ORA Feedback

Big Falls, Trout Lake River
There are currently three pumped storage projects going through the planning and approvals process, that would add approximately 2,000 MW of electricity to the grid. Developing that same Installed Capacity from small hydroelectric projects would involve 200 – 10 MW proposals that would cause untold environmental damage to dozens of Ontario rivers. It is imperative the province does not rush or over-reach its targets and develop new electricity projects unnecessarily.
So What’s the Dam Problem
Well there are several problems, but we may as well start with the root of the problem, and that is a provincial government bent on building its reputation as a Green Energy leader, and attracting big business into this Province to exploit its resources and sell off Crown land to private companies. Democracy for the people and protecting our environment and natural resources isn’t high on their list of priorities. “Ontario is open for business.”
Currently there are 86 hydroelectric dam proposals going through the approvals process in the Province of Ontario, and the 2005 Hatch Acres Report lists about 600 potential sites. Many of these dams are slated for “modified peaking”, a method of holding water back for up to 48 hours in head ponds, for release during peak demand hours. So that leads us to the next on our list of problems…. Continue reading

Pimicikamak Okimawin opposed to Northern Manitoba dams

Excerpt – Read full article here.
Members of Pimicikamak Okimawin – the traditional government of Pimicikamak, an indigenous nation that includes but is not equivalent to Cross Lake First Nation – and other Northern Manitoba communities affected by flooding from the building of Manitoba Hydro dams in the past gathered at the Mystery Lake Hotel in Thompson, which is owned by Nisichawaysihk Cree Nation, on May to voice their opposition to further dam-building while the Public Utilities Board was hearing presentations from the public inside as part of the Needs For and Alternatives To Review (NFAT) of the Crown corporation’s preferred development plan.
“Hydro talks about partnerships with First Nations,” said a printed copy of remarks made by Pimicikamak vice-chief Shirley Robinson, who spoke at the gathering. “But its northern partners only make up about one-third of hydro-affected Aboriginal people in the north. For two thirds of us – in Cross Lake, South Indian Lake, Norway House, Grand Rapids, Easterville and Moose Lake – this so-called new era is just the same as the old era. It is an era of disrespect.”
“Our people have said no more dams, our elders have spoken, our women have spoken,” said David Lee Roy Muswaggon, a member of Pimicikamak’s executive council, which along with the women’s council, elders’ council and youth council make up the First Nation’s traditional government structure. “They said no more dams because in the Northern Flood agreement they said, they promised to assess the cumulative effects of existing dams today. We can’t keep building dams without knowing what damage has been done to the current river and lake system for people that do not hunt, fish or trap. Thousands of miles have been eroded. The ecosystem has been destroyed and decimated. Spawning grounds, everything. Our fish are no longer healthy. Our animals are no longer healthy. People need to understand that hydro is not clean and green.” Continue reading

American Eel Recovery Strategy – EBR Posting 012-0405 – ORA Submission

American Eel
Excerpt:
“American Eels were once abundant in the upper St. Lawrence River, Ottawa River, Lake Ontario, and their tributaries, and in fact were so plentiful that they were an invaluable source of sustenance to First Nation communities and early European settlers, and more recently supported thriving commercial and sports fisheries. This all changed with the advent of a multitude of hydroelectric dams constructed within the historic range of the species.
Key to the American Eel’s survival and recovery is its ability to migrate to its spawning area in the Sargasso Sea, near Bermuda. This is a perilous journey that only a very small percentage ever complete due to the cumulative effects of the numerous hydroelectric facilities that have killed, maimed, and cut off migration to their spawning area. Consequently their once thriving populations have been reduced to a mere one percent of their original numbers.” Continue reading
