Machines sold as diagnostic instruments that cannot diagnose anything — what is claimed for them, what testing shows, and what Canadian regulators have and have not done about them.
Every page in this section ends at the same place: a regulatory record with almost nothing in it. If you have seen one of these devices advertised, been offered a scan, or paid for one, there are four federal routes and one provincial route open to you — and they are not equally useful.
How to complain, and to whom →
Current contact details for the Competition Bureau, Health Canada's enforcement branch, the Canadian Anti-Fraud Centre and the Minister of Health, verified July 2026, with an honest account of what each body can and cannot do.
The other case-file sections on this site are organised around people. This one is organised around hardware.
There is a reason for the distinction. A device outlives any individual practitioner. It gets rebranded, resold, imported through a different channel, and taken up by a new cohort who have never heard of the last regulatory action against it. The Vegatest of the 1990s is the electrodermal screening system of the 2020s under another name. Documenting the machine, and the paper trail attached to it, is more durable than documenting whoever happens to be operating one this year.
Read one at a time, each machine below produces the same shrug — unproven device, some regulatory noise, no consequences. Set side by side, the gap is in the same place every time. Across five devices, two countries and thirty years, every occasion on which one of these machines has been reached by the law, it was reached through some other handle: unlicensed practice, false advertising, elder abuse, import control, a title offence. Nobody has been convicted for selling a diagnosis that does not work. And it is not a limit of the law — a man in South Dakota got nine years for posting people a fake cancer result, and the Competition Act produced $70,000 against a slimming machine in 2006. Start here.
Three tables — the argument of this whole sectionThe same record as a chart. Everything the promoters did on one track, everything the regulators did on the other, from 2001 to 2026. The upper track runs the full width — mobile clinics, a front-page objection, an article that ran inside the hospitals, a radio broadcast, full-page advertising, a clinic advertising today. The lower track is essentially a single week in November 2012, a restatement in 2017 that added no new measure, and then a nine-year stretch marked on the chart as empty. It also sets out plainly the one chart we could not build: a year-by-year count of Canadian clinics, and why the data to draw it honestly does not exist.
One axis, twenty-five yearsElectroacupuncture according to Voll and its commercial descendants — Vegatest, Dermatron, Interro, BioMeridian, ZYTO, Asyra and the rest. Six marketing claims set against the record, including the two double-blind studies that tested the Vegatest directly and found it could not separate allergic from non-allergic subjects. Covers the 2002 suspension of four Vega licences, the Ontario physician disciplined in part for Vegatest use, and the anonymised Ontario letter of counsel that is the only naturopathic outcome on record.
Four Health Canada licences suspended, 2002Digital infrared thermal imaging sold as breast cancer screening. Seven claims against the record, the November 2012 week in which Health Canada, the CBSA, two provincial health ministers and Quebec's medical college all moved at once, and the thirteen years since in which no Canadian enforcement proceeding has followed. Includes the distinction the marketing depends on blurring: these cameras are licensed in Canada to measure skin temperature, like a thermometer. For how it was sold to the public, see the newspaper record and the 2006 broadcast; for who sells it in Canada today, see the clinic network; and for what the laboratory at the far end of that network published about the evidence, see the reading laboratory's own review. For the best current scientific case made for the technique, and why it does not support what is being advertised, see the best paper they have.
Not licensed in Canada to screen for breast cancerHulda Clark was born in Rosthern, Saskatchewan. Her two devices were pleaded as devices in a 2003 United States federal complaint, brought under Operation Cure.All — a campaign Health Canada had publicly joined and was thanked by name for assisting. Health Canada itself never named her, never named either machine, and the consumer refunds the settlement produced were for Americans only. Her Canadian division was sold on in 2005 and still offers Syncrometer testing.
No Health Canada action on recordA radionics box claimed to test thousands of substances against the body in seconds, built by a man who left the United States rather than face charges and manufactured it from Budapest. Priced around $13,000 in 2002, with more than three thousand reportedly sold worldwide. American authorities barred it in January 2008 by import alert, a numbered public document anyone can read. It is widely stated that Health Canada barred it here in February 2009 — and every trail leads back to two CBC broadcasts. No departmental instrument has ever surfaced. Seventeen years on, the Canadian position on a machine sold in Canada rests on a television programme.
Canadian ban asserted everywhere, documented nowhereA drop of blood, a microscope and a screen the patient can watch — the most persuasive performance in alternative medicine, because it appears to be happening in front of her. The stacked cells are largely an artifact of the glass and the passing minutes; the theory behind the practice was published in 1925 and superseded. Two blinded specialists agreeing at a kappa of 0.35. A prospective study in which it failed to detect cancer. Three criminal convictions abroad, including two under a 1939 statute and a five-year-eight-month prison sentence in California in May 2025. In Canada, no proceeding of any kind.
Convictions abroad — nothing on the Canadian recordCanada's only accredited naturopathic degree programme does not teach any of this — so where did practitioners learn it, and how did the hardware enter the country? A vendor-sponsored education channel operating from British Columbia since 1972; a supplier network that states in writing that its products carry no Health Canada or FDA registration; and a Canadian website retailing electrodermal instruments today at listed prices from $1,635 to $7,595 — including the exact model named in a QuackeryWatch complaint to the College of Naturopaths of Ontario. Also answers the two enforcement questions directly: Health Canada has seized and prosecuted over unlicensed devices, and has raided a clinic over unauthorised drugs, but has never been recorded taking a diagnostic device out of a licensed practitioner's office.
Primary sources — observed July 2026Breast thermography in Canada is not a scatter of independent local operators who each happened to buy a camera. It is a network run from a single Toronto office, with clinics listed across five provinces and in four other countries, mobile units visiting small Ontario towns that have no cancer centre, and a business opportunity page for anyone who wants to join. Technicians certified by private associations capture the images; one man in Toronto reads them and issues the reports. At no point does the file pass a physician, a radiologist, a hospital or a regulator — and there is no requirement that it should. The same arrangement was already running under a different company in 2001. For what a reading laboratory of exactly this kind has published about the evidence, see the next page.
One reporting hub, clinics in five countriesThe clinic takes the picture; somebody else reads it. In 2013 the principal of the American laboratory that reports for network partners in the United States and Canada published a two-part review of the breast thermography literature in the field's own journal. It states that the technique cannot consistently tell a malignant lesion from a benign one, that an abnormal image is an indication for a follow-up examination and nothing more, and — in the abstract — that there is little reliable, publicly available evidence on its effectiveness. It also observes that private clinic websites misuse the one study they most often cite. Twelve marketing claims are set beside his own pages, including the sensitivity of 28.3 per cent, and the positive predictive value of 0.7 per cent, that his own table gives for predicting a cancer five years ahead. For the strongest recent paper on the other side, and what it actually endorses, see the next page.
The industry's own reader, in the industry's own journalSince June 2025 the clinics have had a new citation: a review in an indexed oncology journal arguing that radiologists wrote breast thermography off too early, and that the position statements against it are overdue for revision. It is a real paper, openly licensed, by publicly funded authors who declare no commercial interest — and read carefully it is not on their side. What it asks for is adjunctive use only, computer analysis of the measured temperature of every pixel, prospective trials that have not been run, and a reporting standard that does not exist. What it says about clinics that sell thermography as a replacement for mammography, and that grade colour images by eye, is that they are one of the main reasons the technique has no credibility. Its own pooled specificity of 71.8 per cent would mean roughly 280 healthy women in every thousand told their result was abnormal. And its largest study of asymptomatic women with dense breasts — the group the advertising targets hardest — returned a sensitivity of 58.3 per cent, and missed five cancers that mammography found.
The strongest paper for it argues against the clinicsNineteen clippings from Canadian newspapers and the hospital trade press between 2002 and 2019 — front pages, wire briefs, health features, a naturopath's own bylined column, letters to the editor, a full broadsheet page of paid advertising, and an advertorial signed by a chiropractor. The finding is the interval: the medical objection to selling breast thermograms ran on the front page of a small Ontario daily in June 2002, ten years and five months before Health Canada's advisory, and the advertising continued for three and a half years after it. When the advisory finally came, the wire story ran for two days and no paper appears to have gone back through its own advertising log.
19 clippings — 2002 to 2019Nine years before Health Canada's advisory, the founder of that Toronto network set out the whole case for breast thermography on a late-night internet radio programme hosted by a self-described psychic, who spoke more than four times as much as the guest he had invited on. The argument he made that night — that a tumour visible on a mammogram has been growing for nine or ten years, and that he may see it at year one — is the same claim being advertised in Waterloo Region in 2026. Also records the hedges he offered, which the current advertising has dropped, and reads the public register of the physician whose wellness centre stood next door.
Primary source — 11 June 2006The same programme, three weeks before, with the physician from next door as the sole guest. The page opens with a verification table setting out, timestamp by timestamp, which passages were checked against the recording and which were not — because a transcript of a twenty-year-old internet broadcast is only as good as its provenance. What follows includes a two-and-a-half hour homeopathic intake described admiringly, a patient said to have gone ten years with untreated breast cancer, and the host's own on-air disclaimer that he is not licensed to do any of this. Read it beside the June programme: the operator's case and the physician's case, three weeks apart, on the same show.
Primary source — 21 May 2006Five reference tables. Every provincial naturopathic regulator, province by province, and what each has done about registrants using these devices. Every Health Canada device action — licence suspensions, advisories, the CBSA border alert, MDALL and establishment licensing. The other Canadian bodies that did act, including the ones with no jurisdiction over naturopaths at all. Whether anyone has ever been fined. And what the insurers and public payers who assess tests for a living concluded, the earliest of them in 1984. The headline finding: across six provinces with regulated naturopathic colleges, no published discipline decision naming either device could be located.
Reference tables — corrections wantedSellers of other unapproved medical devices have gone to prison — twelve years in one South Dakota case, which also put a distributor from Ontario in an American cell while Canada did nothing. For breast thermography specifically, the published records of the FDA, the Department of Justice and the state licensing boards contain no criminal charge at all. What they do contain: six FDA warning letters between 2011 and 2019, one of them to a well-known osteopathic physician and publisher, and a single chiropractic licence surrendered in California in 2023 on allegations that were almost entirely about breast imaging.
No conviction anywhere on recordFour federal routes with current contact details, verified July 2026 — the Competition Bureau, which is the strongest on the evidence and the only one that ever produced a penalty; Health Canada's Regulatory Operations and Enforcement Branch, with the consumer device form built for exactly this; the Canadian Anti-Fraud Centre, which is a data repository rather than an investigator and is listed with that caveat stated; and the Minister of Health, which is political pressure and not a complaint mechanism. Plus the provincial colleges, which the federal bodies cannot reach, and the access-to-information step that turns a year of complaints into a publishable number.
