In Ontario, med spa advertising is regulated by the College of Physicians and Surgeons of Ontario (CPSO) under the Medicine Act, 1991, with additional oversight from Health Canada under the Food and Drugs Act. Med spas are physician-led medical aesthetics practices, and the physician (or delegated nurse practitioner) bears regulatory responsibility for all advertising. Physicians may not use testimonials or endorsements, may not make superiority claims or guarantee outcomes (especially for cosmetic procedures), may not use misleading before-and-after photos, and may not promote off-label uses of Health Canada-approved devices or drugs. The safest, most effective way to market a med spa in Ontario is educational content — answering patients' and clients' questions — which is fully compliant and also what ranks in local and AI search.
Who regulates med spa advertising in Ontario?
The CPSO — not the Canadian Medical Association (CMA) or Ontario Medical Association (OMA), which are professional associations, not regulators. The CPSO sets and enforces the advertising standards Ontario physicians must follow, grounded in the professional-misconduct provisions of the Medicine Act, 1991. Health Canada provides additional oversight for medical device claims (such as lasers used in aesthetics) and drug/product claims under the Food and Drugs Act. This dual regulation makes med spa advertising the most complex of any specialty in Ontario.
What Ontario med spas cannot do in advertising
- Use testimonials or endorsements. The CPSO prohibits publishing testimonials, endorsements, or patient reviews on a practice's own website, social media, or any advertising the practice controls.
- Use misleading before-and-after photos. Photos must not be digitally altered, cherry-picked to misrepresent typical results, or presented without appropriate context. This is the most scrutinized area for cosmetic practices.
- Make superiority or comparative claims. "Best med spa," "#1 in Toronto," or claims that one practice is superior to others are not permitted without verifiable evidence — which is effectively impossible for such claims.
- Guarantee outcomes. This is especially important for cosmetic procedures given their elective, commercial nature. Creating a false impression of clinical outcomes is prohibited.
- Promote off-label uses of treatments. Advertising treatments outside of Health Canada-approved indications for devices or drugs is not permitted.
- Make unapproved drug or device claims. Health Canada regulates what can be claimed about medical devices (lasers, injectables delivery systems) and drugs used in aesthetics.
- Use pressure tactics or inducements. Tactics designed to pressure patients into elective cosmetic procedures are prohibited.
- Misrepresent who performs procedures. Advertising must be clear about which procedures are performed by physicians versus nurses versus aestheticians. Claiming procedures are performed by qualified staff when they are not is prohibited.
What Ontario med spas can do
- State factual information: procedures offered, physician credentials, technology used, clinic hours, location.
- Publish educational content about cosmetic procedures, skincare, what to expect during and after treatment, and recovery timelines.
- Share general information about treatment options that helps patients and clients make informed decisions.
- Provide accurate descriptions of the technology and approaches used in the practice.
- Use representative before-and-after photos with appropriate context, provided they are not digitally altered, not cherry-picked to misrepresent typical results, and include relevant disclosures.
The grey areas everyone asks about
Google reviews
The same pattern as other CPSO-regulated specialties: you cannot solicit testimonials, cannot repost patient reviews into your own advertising, and must take reasonable steps to disable testimonial features on channels you control. You generally can't stop patients from independently leaving a Google review — that's their speech on a platform you don't operate — but you must not incorporate those reviews into your marketing or a review widget on your own site.
Before-and-after photos
This is the biggest grey area for med spas. Before-and-after photos are not outright banned, but they are heavily restricted. Photos must be representative of typical results, must not be digitally enhanced or altered, must not be cherry-picked to show only the best outcomes, and must include appropriate context (such as the specific treatment, number of sessions, and realistic expectations). Misleading before-and-after imagery is prohibited by both the CPSO and Health Canada advertising standards. When in doubt, err on the side of more context and disclosure.
Delegation and staff qualifications
Advertising must be clear about which procedures are performed by physicians, which by nurse practitioners or registered nurses, and which by aestheticians. The delegation rules require that the supervising physician takes responsibility, and advertising should not create the impression that unqualified staff are performing medical procedures.

How to market a med spa in Ontario without breaking the rules
The tactics that are compliant — consistent, accurate, educational content — are also the ones that win local search and AI recommendations. A med spa that publishes clear answers to the questions patients and clients actually ask ("what to expect after Botox," "how laser skin resurfacing works," "recovery timeline for microneedling") builds visibility the compliant way, while a practice leaning on testimonials, doctored before-and-after photos, or off-label claims risks complaints from both the CPSO and Health Canada for no durable SEO benefit.
The dual regulation from CPSO and Health Canada means med spa advertising requires more care than most specialties. But the compliant path — factual, educational, genuinely helpful content — is also the one that performs best in search.
