Hydro Impacts 101: The Trade-offs

We’ve been sold the idea that hydropower is a clean, green, and non-emitting energy source.
But this is far from the truth!💔🌱

Check out this eye-opening infographic and the full report below to learn more about the hidden environmental and socio-economic costs of these projects! 🌊💰

Hydro Impacts 101 – The Trade-offs


ERO-019-7598 – Proposed Regulatory Amendments to the Build More Mines Act, 2023

“Open-pit Cppper Mine – Mission Complex” by docentjoyce is licensed under CC BY 2.0.

Actually, this government does not deserve the trust of its constituents because it has eroded all of our environmental protections and public engagement and consultation in related policy and legislation over the last 5 years. Therefore, when it claims that “the intention is not to fundamentally change the underlying rules but rather to clarify their source and application”, it is unbelievable – no longer credible – trust has been lost.  Especially since this proposal and the entire Build More Mines Act, 2023 was a total gutting of the Mining Act.

While streamlining mining legislation and policies can bring about certain benefits such as increased efficiency and reduced bureaucracy if done correctly; excessive streamlining without adequate safeguards can impact the environment, communities and even the long-term sustainability of the mining industry.  It will also lead to environmental degradation, community displacement and conflicts, social and economic imbalances, and undermine public trust with the lack of transparency and accountability.

To avoid these negative consequences, it is essential to strike a balance between streamlining mining regulations for efficiency and ensuring that there are robust environmental, social and legal safeguards in place. Proper consultation with local communities, adherence to international best practices and strict enforcement of responsible mining standards are crucial for achieving sustainable and responsible mining practices. This is not the case with any of these amendments.

Consequently, ORA rejects this proposal to streamline the Regulation.

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.


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 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


Coniston Generating Station Upgrade – Life Extension Project

Hydroelectric is not emission-free or clean. A Washington State University study on the effects of damming conducted in a central European impounded river revealed that the reservoir reaches are a major source of methane emissions and that areal emission rates far exceed previous estimates for temperate reservoirs or rivers. It showed that sediment accumulation correlates with methane production and subsequent ebullitive release rates. Results suggested that sedimentation-driven methane emissions from dammed river hot spot sites can potentially increase global freshwater emissions by up to 7%.[1]  Hydroelectric facilities need to acknowledge and account for the associated GHG emissions they produce.

WWF-Canada and Nature Conservancy Support Adding Turbines to Non-powered Dams

It is challenging to understand the logic of a November 2021 CBC article that reports, “The Nature Conservancy and the World Wildlife Fund are two environmental groups that oppose new hydro dams because they can block fish migration, harm water quality, damage surrounding ecosystems and release methane and CO2. But they say adding turbines to non-powered dams can be part of a shift toward low-impact hydro projects that can support expansion of solar and wind power.” Whether it’s a new dam or an older retrofitted dam, they will result in the same negative impacts and produce the same amount of methane for 70 to 100 years or more.

Expand on Protected Areas in Ontario – Joint

Protected areas are a proven means of conserving biological diversity and mitigating the impacts of climate change, two of the greatest challenges we face as a society.  They also enjoy broad public support. For example, a 2018 national survey conducted by IPSOS found that 93 percent of Canadians believe that protected areas are necessary. Similarly, a 2019 national survey conducted by Abacus Data found that 88 percent of Ontarians support protecting or conserving more natural spaces and 91 percent supported Canada’s 2020 protected areas commitment. There is no doubt where the public interest lies on this issue.

Erin WWTP: Designation Request for a federal review under the Impact Assessment Act

West Credit River, by Steve Noakes.

The West Credit River subwatershed supports headwater tributaries of the Credit River and is considered the crown jewel of coldwater Brook Trout fisheries in southern Ontario. The entire footprint of the Project, including the network of underground sewers, will result in numerous crossings of first, second and third order streams. Additionally, the West Credit River feeds into the main Credit River at the Forks of the Credit Provincial Park. This area is part of the UNESCO Niagara Escarpment World Biosphere Reserve (Reserve), home to several sensitive fish species, including the endangered Redside Dace and Atlantic Salmon. Atlantic Salmon, historically extirpated, are being reintroduced as part of the broader Lake Ontario Atlantic Salmon Recovery Program. This Reserve is within 1 km downstream of the Project’s effluent discharge, and Redside Dace (Schedule 1, Species at Risk Act, 2002), are known to occupy the West Credit River within 4 km downstream of the effluent diffuser.
