Ask whether a longevity clinic is regulated and you will get an answer. Ask what it is regulated as, and the answer changes at every border.

We spent this week reading the primary law in four jurisdictions: Hong Kong, Canada, Thailand and Vietnam. Not one of them has a licence category for longevity or anti-ageing medicine. The category exists commercially and, in these four, it does not exist legally. What each country does instead is pick a different point in the business and regulate that.

That is not a claim about everywhere. A dedicated longevity clinic standard does exist, in Abu Dhabi, and on the sources checked it is the only one in effect anywhere.1 These four are the far more common case: no category has been created, so a clinic is regulated by whichever instrument reaches it first.

Hong Kong regulates the premises

Hong Kong’s Private Healthcare Facilities Ordinance recognizes four kinds of private healthcare facility: hospitals, day procedure centres, clinics and health services establishments. A clinic offering longevity and preventive services is regulated as one of those four, and the one it falls into is the clinic. Nothing in the scheme is more specific than that.2

What makes this live is the timing. Clinic licensing commenced on 13 October 2025. A clinic already operating on 30 November 2018 could apply for a provisional clinic licence between 13 October 2025 and 13 April 2026, and that window has closed. A clinic that opened after 30 November 2018 applies directly for a full clinic licence.3

Exemption as a small practice clinic exists, and its test is about who owns the clinic rather than what the clinic does. The clinic must be operated solely by registered medical practitioners or dentists, with no more than five partners or directors, all of them registered practitioners.3 An investor-owned clinic does not qualify, however small it is.

Canada regulates the money

Canada’s control point is not the building and not the practitioner. It is the bill.

A provincial health care insurance plan must not permit extra-billing or user charges. Those restrictions attach to insured health services, and a service that is not insured falls outside them.4 The dividing line is insured against uninsured, not longevity against conventional.

Ontario has a statute that looks like it should reach a private preventive clinic and does not. Its licensing regime for integrated community health services centres, also called community surgical and diagnostic centres, is keyed to services for which facility costs are paid by the province.5 A service the patient pays for is outside that keying, which is a matter of definition rather than of exemption.

Ontario’s premises regime is separate again, and it triggers on the procedures performed rather than on the kind of clinic performing them. What brings a premises into it is procedures carried out under anaesthesia or sedation, and specified cosmetic procedures. A premises performing only consultations, blood testing or imaging does not require notification.6

Thailand regulates the claim

Thailand’s clinic types are keyed to the profession practised, covering medical, dental, nursing and midwifery, physiotherapy, medical technology, Thai traditional medicine and the arts-of-healing branches, together with a specialised type keyed to the practitioner’s own certified specialty and a multi-discipline type. No type is defined by longevity or anti-ageing medicine.7

What Thai law regulates most closely is what a facility says about itself. A sanatorium, the licensed facility class the clinic types sit inside, may not advertise its name, its location, its business, or the qualifications or ability of its practitioners using statements that are false or exaggerated beyond the truth, or that are likely to cause material misunderstanding about the business.8 The facility’s own name sits inside that rule.

Advertising relating to a sanatorium also requires prior approval from the licensor, beyond the name and location shown on the licence.9 That is approval before publication rather than correction after it.

For a clinic that markets itself across borders, that is a more consequential constraint than any category question.

Vietnam regulates the practitioner, on a clock

Vietnam rewrote its medical practice law with effect from 1 January 2024. A practice certificate issued before that date converts to a practising licence, and that licence is renewed every five years from the date of conversion.10

A national assessment of professional competency, organized by the National Medical Council, is being phased in. It applies from 1 January 2027 for doctors, from 1 January 2028 for physician assistants, nurses and midwives, and from 1 January 2029 for medical technicians, clinical nutritionists, out of hospital emergency responders and clinical psychologists. Doctors applying for a licence between 1 January 2024 and 31 December 2026 are not required to sit it.11

That exemption window closes at the end of this year.

Why this matters more than a category would

An operator running clinics in all four of these markets satisfies four unrelated regimes. Compliance in one predicts nothing about the next. A Hong Kong licence says something about the room. A Canadian arrangement says something about the invoice. Thai approval says something about the advertisement. A Vietnamese licence says something about the doctor, and says it again in five years.

For anyone comparing clinics across borders, “is it regulated” is not a question with a yes or no answer. The useful question is which lever that country pulls, and whether the clinic has satisfied it.

What we did not check

Canada was checked at the federal level and in Ontario only. British Columbia, Alberta, Quebec and the other provinces regulate premises and billing separately and were not examined.

Thailand’s list of clinic types was read from the Department’s published guidance and Parliament’s compilation of the Act rather than from the Royal Gazette text, so the completeness of that list is not independently confirmed. The notification carrying the advertising approval regime is cited by title and year, because the Department page that carries it did not respond when it was checked.

Vietnam’s list of permitted facility forms was read from the Ministry’s own summary of the implementing decree rather than from the decree text, and that summary introduces the forms as examples rather than as a closed list.

Cell and gene therapy, laboratory regulation and product approval were outside this pass in every one of the four, as were Hong Kong’s medical advertising rules and Canada’s rules on natural health products, medical devices and advertising.

Nothing here describes the licence status of any particular clinic.

The Atlas of the Healthspan Economy is a neutral record of organizations working on healthspan. It does not recommend any provider and does not give legal advice. The regulatory record for each market, with its issuers, instruments, dates and primary links, sits on the country page: Hong Kong, Canada, Thailand and Vietnam. Read the methodology.

A note on what this piece does not claim. Nothing here is legal advice. No operator recorded in any of these four markets is named, and nothing here describes the licence, registration or advertising status of any clinic, facility or individual practitioner. Each finding is bounded by what the pass covered, which is set out above.
