Health Risks from Water Fluoridation are not just in RFK’s Head

From the Frontier Centre for Public Policy
By Lee Harding
“There is evidence that fluoride exposure has been associated with the diseases [and] disorders that RFK listed, but with caveats”
Water fluoridation has returned to the forefront of public policy debates thanks to environmental lawyer Robert F. Kennedy Jr. Kennedy is expected to have a role in the Department of Health and Human Services, giving his opinion more weight than ever.
In a post to X, Kennedy wrote, “On January 20, the Trump White House will advise all U.S. water systems to remove fluoride from public water. Fluoride is an industrial waste associated with arthritis, bone fractures, bone cancer, IQ loss, neurodevelopmental disorders, and thyroid disease.”
The post links to a High Wire video interview with lawyer Michael Connett, lead attorney in a successful case against the Environmental Protection Agency (EPA). Last September, Obama-appointed District Court Judge Edward Chen sided with Connett and mandated the EPA to more strictly regulate water fluoridation.
Chen’s ruling states, “In all, there is substantial and scientifically credible evidence establishing that fluoride poses a risk to human health; it is associated with a reduction in the IQ of children and is hazardous at dosages that are far too close to fluoride levels in the drinking water…”
Fluoride is a poisonous industrial byproduct, handled in its pure form by people in hazmat suits. Dealing with sodium fluoroacetate was an expense for the Aluminum Company of America before Edward Bernays helped turn it into a profitable venture. In the 1940s, Bernays, the father of modern public relations and nephew of psychoanalyst Sigmund Freud, used mass psychology and public health advocates to have fluoride put in drinking water. Fluoridation opponents were dismissed as kooks ever after.
The toxicology adage “The dose makes the poison” applies. Chemicals, including drugs, can benefit health in some respects but undermine it in others. Unfortunately, recent analysis suggests the “side effects” of fluoridation may outweigh its alleged benefits.
A recent analysis by Cochrane Reviews said water fluoridation may provide a slight dental benefit, but less so since the mid 70’s when manufacturers commonly added fluoride to toothpaste. Fluoride reverses or stops early tooth decay by remineralizing teeth, making them stronger. It also reduces bacteria’s ability to make acids that cause decay.
Fluoride capsules have little effect on teeth, which suggests its main positive effect is topical (meaning by direct contact). An obvious question follows: if fluoride of roughly one part per million passing over the teeth before swallowing, what is its effect during digestion or bodily storage? After all half of fluoride is passed through urine, while the remainder is stored in the body.
In 2020 The Institute of Technology and Business in the Czech Republic made a six-article issue dedicated to the mechanisms of fluoride toxicity. One explained in the abstract that “fluoride is an enzymatic poison, inducing oxidative stress, hormonal disruptions, and neurotoxicity.” The toxic effects were magnified when trace amounts of aluminum were present, and “might contribute to unexpected epidemics in the future.”
Sleeplessness, hypothyroidism, and autism to conditions linked to fluoride consumption, whether through natural sources or water fluoridation. The risks were found through statistical studies comparing health issues in water fluoridated and non-fluoridated areas, biochemical analysis, and human and animal studies.
“We concur with the conclusions of many authors over the world that fluoride neurotoxicity is a serious risk associated with elevated fluoride exposure… […] Fluoride toxicity is a slow, hidden process. Evolving evidence should inspire scientists and health authorities to re-evaluate claims about the safety of fluoride…”
In 2019, researchers from Canadian and U.S. universities tested over 500 Canadian women throughout their pregnancies for fluoride levels in their urine. Their study, published in the Journal of the American Medical Association (JAMA), found that for each milligram of fluoride per litre in the mother’s urine, IQ dropped 4.5 points in their male children tested at ages of three to four years.
Christine Till, a professor in the Department of Psychology at York University in Toronto, told CNN, “At a population level, that’s a big shift. That translates to millions of IQ levels lost.”
Ashley Malin, an assistant professor in the University of Florida’s Epidemiology Department, had similar findings in her Florida study, published in JAMA in 2024.
“There is evidence that fluoride exposure has been associated with the diseases [and] disorders that RFK listed, but with caveats,” Malin told the Virginia Mercury in a recent article.
“Aside from fluoride’s impacts on neurodevelopment, I think that there is more that we don’t know about health effects of low-level fluoride exposure than what we do know, particularly for adult health outcomes,” Malin added.
In August, the National Toxicology Program (NTP) in the United States found that fluoride levels higher than 1.5 mg/L (the highest acceptable level in Canada) are associated with lower IQs in children. The NTP said there is insufficient evidence to conclude that there are similar risks at the recommended level of 0.7 mg/L.
Montreal recently ended its water fluoridation and hopefully other cities will follow. Only a misguided nanny state would poison young minds and old bones for the sake of people who don’t brush their teeth.

Trust but verify: Why COVID-19 And Kamloops Claims Demand Scientific Scrutiny

From the Frontier Centre for Public Policy
Senior Fellow Rodney Clifton calls for renewed scientific scrutiny of two major Canadian narratives: COVID-19 policies and the Kamloops residential school claims. He argues that both bypassed rigorous, evidence-based evaluation, favouring politicized consensus. Critics of pandemic measures, like Dr. Jay Bhattacharya, were wrongly dismissed despite valid concerns. Similarly, the unverified mass grave claims in Kamloops were accepted without forensic proof. Clifton urges a return to the scientific principle of “trust but verify” to safeguard truth, public policy, and democracy.
COVID-19 and Kamloops claims dodged scrutiny – but the truth is catching up
Do we know the best way to decide if specific empirical claims are true?
Of course we do. The best way is by using the procedures of science.
Scientists critically examine the arguments and evidence in research studies to find weaknesses and fallacies. If there are no weaknesses or fallacies, the evidence enters the realm of science. But if there are weaknesses, the research has low or zero credibility, and the evidence does not become a building block of science.
In a historical context, seemingly good evidence may not remain as science because claims are continually evaluated by researchers. This scientific process is not failsafe, but it is far better than other procedures for determining the truth of empirical claims.
This powerful principle is often called “trust but verify,” and it is the idea behind the replication of scientific results.
Today, many such truth claims demand critical examination. At least two come readily to mind.
The first is the claim that the COVID-19 procedures and vaccines were safe and effective.
It is now abundantly clear that the procedures used during the COVID-19 pandemic bypassed time tested scientific protocols. Instead of open scientific debate and rigorous testing, government appointed “scientists” endorsed government-approved narratives. Canadians were told to social distance, wear masks and, most importantly, get vaccinated—often without transparent discussion of the evidence or risks.
Those who questioned the procedures, vaccines or official explanations were dismissed as “deniers” and, in some cases, ridiculed. Perhaps the most notable example is Dr. Jay Bhattacharya, the Stanford epidemiologist and economist who co-authored the Great Barrington Declaration. Despite being vilified during the pandemic, Dr. Bhattacharya is now the head of the U.S. National Institute of Health.
Five years after the pandemic began, it is clear that Dr. Bhattacharya—and many other so-called deniers—were raising legitimate concerns. Contrary to the portrayal of these scientists as conspiracy theorists or extremists, they were doing exactly what good scientists should do: trusting but verifying empirical claims. Their skepticism was warranted, particularly regarding both the severity of the virus and the safety and effectiveness of the vaccines.
The second claim concerns the allegation that Indigenous children died or were murdered and buried in unmarked graves at the Kamloops Residential School.
In 2021, the Kamloops Indigenous Band claimed that 215 children’s bodies had been discovered in the schoolyard. The legacy media swiftly labelled anyone who questioned the claim as a “denier.” Despite millions of dollars allocated for excavations, no bodies have been exhumed. Meanwhile, other bands have made similar claims, likely encouraged by federal government incentives tied to funding.
To date, this claim has not faced normal scientific scrutiny. The debate remains lopsided, with one side citing the memories of unnamed elders—referred to as “knowledge-keepers”—while the other side calls for forensic evidence before accepting the claim.
The allegation of mass graves was not only embraced by the media but also by Parliament. Members of the House of Commons passed a motion by NDP MP Leah Gazan declaring that Indigenous children were subjected to genocide in residential schools. Disturbingly, this motion passed without any demand for forensic or corroborating evidence.
Truth claims must always be open to scrutiny. Those who challenge prevailing narratives should not be disparaged but rather respected, even if they are later proven wrong, because they are upholding the essential principle of science. It is time to reaffirm the vital importance of verifying evidence to resolve empirical questions.
We still need a robust debate about COVID-19 procedures, the virus itself, the vaccines and the claims of mass graves at residential schools. More broadly, we need open, evidence-based debates on many pressing empirical claims. Preserving our democracy and creating sound public policy depend on it because verifiable evidence is the cornerstone of decision-making that serves all Canadians.

Banks
TD Bank Account Closures Expose Chinese Hybrid Warfare Threat

From the Frontier Centre for Public Policy
Scott McGregor warns that Chinese hybrid warfare is no longer hypothetical—it’s unfolding in Canada now. TD Bank’s closure of CCP-linked accounts highlights the rising infiltration of financial interests. From cyberattacks to guanxi-driven influence, Canada’s institutions face a systemic threat. As banks sound the alarm, Ottawa dithers. McGregor calls for urgent, whole-of-society action before foreign interference further erodes our sovereignty.
Chinese hybrid warfare isn’t coming. It’s here. And Canada’s response has been dangerously complacent
The recent revelation by The Globe and Mail that TD Bank has closed accounts linked to pro-China groups—including those associated with former Liberal MP Han Dong—should not be dismissed as routine risk management. Rather, it is a visible sign of a much deeper and more insidious campaign: a hybrid war being waged by the Chinese Communist Party (CCP) across Canada’s political, economic and digital spheres.
TD Bank’s move—reportedly driven by “reputational risk” and concerns over foreign interference—marks a rare, public signal from the private sector. Politically exposed persons (PEPs), a term used in banking and intelligence circles to denote individuals vulnerable to corruption or manipulation, were reportedly among those flagged. When a leading Canadian bank takes action while the government remains hesitant, it suggests the threat is no longer theoretical. It is here.
Hybrid warfare refers to the use of non-military tools—such as cyberattacks, financial manipulation, political influence and disinformation—to erode a nation’s sovereignty and resilience from within. In The Mosaic Effect: How the Chinese Communist Party Started a Hybrid War in America’s Backyard, co-authored with Ina Mitchell, we detailed how the CCP has developed a complex and opaque architecture of influence within Canadian institutions. What we’re seeing now is the slow unravelling of that system, one bank record at a time.
Financial manipulation is a key component of this strategy. CCP-linked actors often use opaque payment systems—such as WeChat Pay, UnionPay or cryptocurrency—to move money outside traditional compliance structures. These platforms facilitate the unchecked flow of funds into Canadian sectors like real estate, academia and infrastructure, many of which are tied to national security and economic competitiveness.
Layered into this is China’s corporate-social credit system. While framed as a financial scoring tool, it also functions as a mechanism of political control, compelling Chinese firms and individuals—even abroad—to align with party objectives. In this context, there is no such thing as a genuinely independent Chinese company.
Complementing these structural tools is guanxi—a Chinese system of interpersonal networks and mutual obligations. Though rooted in trust, guanxi can be repurposed to quietly influence decision-makers, bypass oversight and secure insider deals. In the wrong hands, it becomes an informal channel of foreign control.
Meanwhile, Canada continues to face escalating cyberattacks linked to the Chinese state. These operations have targeted government agencies and private firms, stealing sensitive data, compromising infrastructure and undermining public confidence. These are not isolated intrusions—they are part of a broader effort to weaken Canada’s digital, economic and democratic institutions.
The TD Bank decision should be seen as a bellwether. Financial institutions are increasingly on the front lines of this undeclared conflict. Their actions raise an urgent question: if private-sector actors recognize the risk, why hasn’t the federal government acted more decisively?
The issue of Chinese interference has made headlines in recent years, from allegations of election meddling to intimidation of diaspora communities. TD’s decision adds a new financial layer to this growing concern.
Canada cannot afford to respond with fragmented, reactive policies. What’s needed is a whole-of-society response: new legislation to address foreign interference, strengthened compliance frameworks in finance and technology, and a clear-eyed recognition that hybrid warfare is already being waged on Canadian soil.
The CCP’s strategy is long-term, multidimensional and calculated. It blends political leverage, economic subversion, transnational organized crime and cyber operations. Canada must respond with equal sophistication, coordination and resolve.
The mosaic of influence isn’t forming. It’s already here. Recognizing the full picture is no longer optional. Canadians must demand transparency, accountability and action before more of our institutions fall under foreign control.
