Aesthetician and esthetician are the same job, spelled two ways. In Canada the difference that matters isn’t the spelling. It’s which province you work in, whether you’re in a spa or a medical clinic, and which treatments need a nurse or physician in the room.
The short version
| What it means in Canada | |
|---|---|
| Spelling | Both are correct. “Esthetician” is more common in Canadian job titles and government classifications; “aesthetician” is common in the UK and in med spas |
| Occupation code | Both fall under NOC 63211, “Estheticians, electrologists and related occupations” |
| Licence | Set by each province. Regulated in Manitoba, New Brunswick and Saskatchewan per Job Bank; no individual licence in Ontario or Alberta |
| “Medical aesthetician” | A job title for working in a clinic. It adds no legal authority |
| Injectables | Never within an aesthetician’s scope. Nurses, NPs and physicians only, under provincial rules |
Where the two spellings come from
Both come from the Greek aisthētikos, “of perception”. British English kept the “ae”; American English dropped it, the same way anaesthetic became anesthetic. Canada sits in between, which is why you’ll see both on the same street.
In practice the spelling has picked up a loose connotation. Day spas and studios tend to say esthetician. Med spas and dermatology clinics often say aesthetician, because “aesthetics” is the word the medical side uses for injectables and devices. That’s a branding choice, not a different qualification. If you’re writing a job ad, use whichever spelling your local candidates search for, and put the other in the description.
What actually differs: the province
There’s no national licence for aestheticians. Each province decides, and they don’t agree.
- Manitoba requires trade certification to work in the occupation, according to Job Bank’s requirements page.
- New Brunswick and Saskatchewan list the occupation as regulated, through the Cosmetology Association of New Brunswick and the Saskatchewan Apprenticeship and Trade Certification Commission.
- Nova Scotia lists it as non-regulated, although a cosmetology association exists.
- Ontario doesn’t license the individual. Esthetics is an apprenticeable trade, but unlike hairstyling it isn’t one of the province’s compulsory trades, so no certificate is legally required to work.
- Alberta doesn’t regulate the trade at all.
Ontario regulates the place instead. A studio offering esthetic services is a personal service setting under O. Reg. 136/18. The operator has to notify the local public health unit before opening or adding a new service, record each client’s name and contact details before a service, follow the provincial infection-control guide, and expect inspections, with the results made public. Other provinces have their own public-health rules for personal services. Check with your health unit before you open, not after.
“Medical aesthetician” is a job title
You’ll see “medical aesthetician” and “medical esthetician” in clinic job ads across Canada. It usually means an aesthetician who works in a med spa, dermatology or plastic surgery clinic, doing advanced skin treatments (peels, microneedling, laser and IPL) under the clinic’s protocols, often alongside a nurse injector.
It’s a useful description of the work, but not a credential. Nothing about the title lets the holder do more than any other aesthetician in that province. Clinics hiring for the role usually ask for a provincial esthetics certificate or diploma plus device-specific training, and that’s what to look at on a résumé.
What an aesthetician can’t do, whatever the title
The line that matters most in a med spa is injectables. In Ontario, administering a substance by injection, and performing a procedure on tissue below the dermis, are controlled acts under the Regulated Health Professions Act. Only authorized regulated professionals can perform them, so Botox, fillers and PRP injections are done by nurses, nurse practitioners and physicians. Nurses usually work under an order or medical directive; our news post on Ontario’s nurse aesthetics guideline covers how that works.
Other provinces draw the line in similar places. In British Columbia, a registered nurse giving an injectable for aesthetic purposes needs a client-specific order, and the ordering professional has to be on site and available.
The “below the dermis” rule is also why needle depth matters for microneedling. If you offer it, know where your devices and protocols sit; our microneedling depth calculator lists the usual depths by area.
Why this matters if you run a clinic
For an owner, the title question turns into three practical ones:
- Who can do what. Write your service menu by role: what aestheticians perform, what needs a nurse or physician, and what needs both (a consult and a treatment). That’s also how bookings should be set up, so a client can’t book an injectable into an aesthetician’s column.
- Credentials on file. Keep each provider’s certificate, device training and, for nurses, registration and any medical directive with their staff record, and know when each expires.
- Records that show it. Every treatment record should say who performed it, with what product or device settings, and under which consent. That’s what an inspector, a college or an insurer asks for.
