Learn about the extraordinary American Eel!
It’s a lizard, It’s a snake, It’s one of the most unique fishes in the world: the American Eel!
Known for their elongated bodies and short fins, these fish which were once very common in North American waterbodies, are now endangered. This is largely due to the presence of hydroelectric dams, which block their natural migration routes, making them unable to reach their breeding grounds in the ocean.
Learn more about their impressive migrations, extraordinary life cycle, and current conservation efforts through this short video.
ERO-019-6647 – IESO Pathways to Decarbonization Study

Greenhouse Gas Emissions from Reservoirs
The ORA will never be in favour of streamlining the regulatory, approvals and permitting processes as they were put in place to protect our natural environment and communities, and have already been significantly undermined.
Instead, we need strong and rigorous environmental assessment and robust public, Indigenous and stakeholder consultation if we are to build climate resilience into our air, land and freshwater resources.
I will briefly address my rationale and the dangers of streamlining the regulatory regime of hydroelectric facilities in particular, as it is commonly claimed by governments and industry to be ‘clean’, ‘green’ and ‘non-emitting. However, this is misleading the public at a pivotal time when we should be following the science.

Hydroelectric is not a Pathway to Decarbonization or Net Zero

Dear Ministers Guilbeault, Wilkinson and Champagne,
ORA understands the urgency in fulfilling the vitally important commitment the government has made to cut GHG emissions to 40-45% below 2005 levels by 2030; however, we will present evidence from independent third-party peer-reviewed studies indicating that an effective path to decarbonization is not through hydropower.
ORA’s first Youth Engagement event!
ORA collaborated with Engineers Without Borders (UW Chapter) to host a youth engagement workshop for 35 grade 11 students in St. Aloysius Gonzaga Secondary School on March 31st. The group included students from the STEM Club and from the Environment Specialist High Skills Major (SHSM) Red Seal Program. ORA offered the students a Sector-Partnered Experience (SPE) focusing on real-world environmental issues to be solved. Continue reading
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.
OPG: Proposed Coniston Generating Station Life Extension Project Environmental Report

Wherever water levels have been lifted from their former undeveloped elevation must be considered the full extent of the reservoir/s. This crucial detail is not set out in the ER; however, the full extent of the cascading facilities must be considered when detecting, measuring and reporting total GHG emissions (CH2, CH4 and N2O). This cascading system creates one very large artificial and ongoing multi-level series of reservoirs that are highly regulated through the WRWMP, and likely very high in GHG emissions.
Hydroelectric and its “Pathway to Decarbonization”

Please sign and share our Petition: Hydroelectric is NOT a Pathway to Decarbonization.
The increasing role of hydroelectric reservoirs as GHG emitters and negative environmental effects has resulted in thousands of independent peer-reviewed studies laying out the facts. However, the hydropower industry and governments have done a thorough job of promoting waterpower through a powerful disinformation campaign to mislead the world into believing it is clean and non-emitting while turning a blind eye to the growing body of evidence to the contrary.
ORA strongly recommends that OPG begin the use of drone technology to detect, map and measure GHG emissions within the entire zone of influence of its hydroelectric facilities – in the upstream reservoir, turbine intake, spillway and downstream of the dam. This will ensure that those who have purchased clean energy credits from OPG are getting what is claimed – a clean and non-emitting source of electricity. All data should be placed in real-time on the OPG website and made available to researchers and the public.
In closing, the ORA requests that the Minister finally remove the label of clean and non-emitting from hydroelectric generation. Certification will mean nothing if there is no authentic and verifiable science-based method of reducing Ontario’s GHG emissions. Furthermore, it would be unethical and fraudulent to mislead the public and corporations into believing they are paying for clean and non-emitting electricity when they are actually paying to fuel climate change.
Embro Dam Class Environmental Assessment – Alternatives

There are very few thriving Brook Trout populations left in southern Ontario, and it is especially surprising to find them present as far south as London, Ontario. Brook Trout are a sentinel species – the canary in the coal mine. In southern Ontario, Brook Trout populations have seen an 80% decline in their numbers over the last 50 years. Their populations have been under increasing pressure from a warming climate as well as agricultural, urban, rural and industrial development.
Removing the Dam and headpond to create a free-flowing and healthy coldwater Brook Trout fishery would be the perfect place for a family to go for walk, play or picnic in the Embro Conservation Area. It would provide a healthy riverine ecosystem and a beautiful natural environment for the entire community to enjoy!!
