Bruce Power’s “Nuclear Fish City” is really a giant fish trap.
If you read the publicity around Bruce Power’s April 22 “Nuclear Fish City” live stream event, you might think the company has created something positive: a warm-water refuge where fish gather and thrive beside industry.
That is the image being sold. The reality is much harsher. An area of the water, called a thermal plume, has been heated through the nuclear power production process and released back into the ecologically sensitive Lake Huron. Fish are drawn to this warmer water, especially in colder conditions. But being drawn in does not mean they are safe. It can mean the opposite.
A member of the public only needs to walk along the shore north of Bruce Power and see it littered with thousands of dead fish to raise questions about the message Bruce Power is trying to sell. What is being marketed as a spectacle of abundance, is actually a giant fish trap.
That reality was made brutally clear during last year’s catastrophic gizzard shad fish kill associated with Bruce Power. By the company’s own reporting, close to five million fish were killed.
Five million dead fish is not evidence of ecological success. It is evidence of an industrial system that can attract fish and kill them on a massive scale. No amount of branding can change that.

For us, the Saugeen Ojibway Nation (SON), this is not an abstract environmental debate. Fish are central to SON’s way of life, to food systems, and to cultural relationships that go back generations. These waters have sustained SON since time immemorial. What happens to the fish matters directly to the people.
SON’s concerns are grounded in lived experience, long-term observation, and science. SON fishers and knowledge holders have watched these waters change over generations. Their work combines traditional knowledge with scientific study to understand what is happening to the fish populations.
What that knowledge shows is troubling.
Bruce Power’s heated discharge does not create natural habitat. It creates an artificial gathering point. Fish are drawn to the warmer water and then face risks such as being pinned against intake screens, pulled into cooling systems, or trapped in channels they cannot easily escape. Even lake sturgeon, a threatened and culturally significant species, have been caught in Bruce Power’s system. This is a serious concern.
A place that attracts fish is not necessarily a place that is good for them.
The harm also goes beyond what is visible. Warmed water can change fish behaviour, disrupt natural patterns, and alter local ecosystems. Eggs and larvae can be killed in the cooling-water system long before they ever appear on a camera.
There are also broader warning signs. Invasive species like grass carp have appeared and species like gizzard shad are moving into new areas. These shifts suggest an ecosystem under stress.
This is why fish on camera are not proof of ecological health. A live underwater feed may show fish gathering near a water discharge, but it cannot show what is happening out of view. It cannot show fish pinned against screens, pulled into plant infrastructure, or lost in early life stages. It cannot show the effects of altered water temperatures or the attraction of invasive species. It shows concentration, not health.
That is the problem at the heart of the “Nuclear Fish City” narrative. It asks the public to mistake attraction for habitat, concentration for abundance, and industrial disruption for environmental success.
That matters not just for our First Nations, but for anyone who believes environmental claims should be judged by real impacts, not carefully framed imagery.
SON has not stood aside. We have worked with Bruce Power to reduce some of these harms. But public relations cannot erase a basic truth: when a massive industrial facility changes water temperature and fish behaviour, it needs to take responsibility for ensuring attraction does not become injury or death.
Lake Huron is not an aquarium for corporate storytelling. It is a part of Anishnaabekiing, part of a natural system already under pressure.
What is needed is not better branding, but real change. That means reducing the artificial attraction of fish to dangerous intake and discharge areas, stronger monitoring of what is happening in and around the plant, and real accountability for the harm that has already occurred.
A true environmental success story would not be measured by how many fish gather near the plant. It would be measured by whether the plant stops drawing them into danger in the first place.
If the public wants to watch fish on a camera, they need to ask a harder question: why are those fish there, and what is the camera not showing?
The answer is clear. “Nuclear Fish City” is not a window into nature thriving beside industry. It is a carefully framed glimpse of fish drawn into an industrial system that has already shown it can kill them by the millions.
