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.
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.
Electroacupuncture 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 fourteen 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.
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 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 2026Eighteen clippings from Canadian newspapers 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.
18 clippings — 2002 to 2019Three 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. And the other Canadian bodies that did act, including the ones with no jurisdiction over naturopaths at all. The headline finding: across six provinces with regulated naturopathic colleges, no published discipline decision naming either device could be located.
Reference tables — corrections wantedThe Quantum Xrroid family, built by Bill Nelson and sold from Budapest after he became a fugitive from U.S. charges. Reported to have been barred from sale in Canada in February 2009 following a CBC Marketplace broadcast — a claim currently sourced only to secondary reporting, and one we would like to pin to a primary Health Canada instrument before building the page out.
