The CNO Aesthetic Services guidelineexplained by a Nurse Practitioner

The College of Nurses of Ontario published a practice guideline on aesthetic services in July 2026, and if you are a nurse working in aesthetics you should read the document itself. This page is what it looks like to a practising Nurse Practitioner: what the guideline is, what it actually asks of you, what genuinely changed, and which parts are still open.

The short version is that the guideline creates no new licence, no new certificate and no new permission. It takes expectations that already applied to every nurse and states them in the setting where nurses in aesthetics actually work. That sounds modest. It is not, because expectations that are written down are expectations you can be measured against.

What a practice guideline is, and what it is not

A practice guideline explains how existing standards apply in a particular context. It does not create new law.

CNO issues practice standards, which set out mandatory expectations, and practice guidelines, which help nurses apply those standards to specific situations. The Aesthetic Services guideline is the second kind. It sits alongside the scope of practice standard, the guidance on directives, and the general practice standards, and it should be read with them rather than instead of them.

So nothing in it changes the Regulated Health Professions Act, 1991, the Nursing Act, 1991, or the controlled acts framework. There is still no injector licence in Ontario. No body certifies injectors. Your nursing registration remains the only licence involved.

Why CNO issued it

CNO issued the guideline because aesthetic nursing grew quickly in settings with little of the structure that surrounds nursing elsewhere.

Most nursing happens inside an organisation with policies, chart audits, a clinical educator and colleagues who notice. A great deal of aesthetic nursing happens in a small business, sometimes a business the nurse owns, sometimes a business owned by someone who is not a regulated professional at all. The standards always applied. The scaffolding that helps nurses meet them often did not.

That is the gap the guideline addresses. It is aimed squarely at the nurse working alone in a treatment room with a client, a product and a consent form nobody else has ever reviewed.

What the guideline asks of you

The guideline asks for six things, and none of them will surprise a nurse who has read the general standards.

Competence for the specific intervention. Not aesthetics in general, and not what you were competent in two years ago. The specific product, the specific site, this client.

A valid authorizing mechanism, where one is required. For an RN or RPN injecting, one is required.

Informed consent as a conversation. Realistic outcomes, foreseeable risks, alternatives, cost, and the option of doing nothing, discussed with someone who has the capacity to decide and is not being rushed.

Emergency preparedness proportionate to the risk. You can recognise the complications your treatments can cause, you have the supplies and the plan in the room, and you know your escalation route.

Documentation. Assessment, consent, product, lot, site, volume, technique, outcome, follow-up and anything that went wrong. Written as though someone else will read it, because someone else might.

Restraint in advertising. No guarantees of outcome, no comparative claims, no misleading impression of your qualifications or authority.

The regulatory position, stated plainly

In Ontario, an RN can administer a neuromodulator injection but cannot initiate it independently.

Injecting a neuromodulator or a dermal filler involves two controlled acts under the Regulated Health Professions Act, 1991: administering a substance by injection, and performing a prescribed procedure below the dermis. An RN requires an authorizing mechanism, such as a direct order or a directive, from an authorized provider such as a Nurse Practitioner or physician. (College of Nurses of Ontario, Aesthetic Services practice guideline, published July 2026.)

Two points that most coverage of this subject gets wrong are worth stating explicitly.

First, neuromodulators are prescription drugs in Canada. Dermal fillers are not. Health Canada regulates fillers as Class III medical devices, and as Class IV where the filler is permanent. The authority requirement for fillers therefore flows from the controlled acts, not from drug scheduling. A nurse who reasons that fillers are unregulated because there is no prescription to write has drawn the right conclusion about drug law and the wrong conclusion about their own practice.

Second, a course certificate is not an authorizing mechanism. A certificate is evidence of competence. Authority is a separate thing that comes from an authorized provider. The guideline does not change this, and it makes the distinction harder to fudge.

What actually changed, and what did not

Very little changed in law. A great deal changed in visibility.

What did not change: the controlled acts, the requirement for an authorizing mechanism, your accountability for your own competence, the absence of any injector licence, and the protected titles under the Nursing Act, 1991.

What did change: those expectations are now written down for aesthetics specifically. A directive written against a general understanding of the standards may not obviously fail, but it will look thin next to a document written against the guideline. Consent forms that list risks without recording a conversation now look thin too. If you have been practising carefully, the guideline is a confirmation. If you have been practising on inherited paperwork nobody has reviewed since you were handed it, this is the prompt to review it.

What it means for RNs, RPNs and NPs differently

The guideline applies to all three classes, but it lands differently on each.

Registered Nurses

An RN needs an authorizing mechanism to initiate, and the guideline gives you a clearer basis for asking whether yours is adequate. Read your directive against the six expectations above. Does it name the specific interventions you actually perform? Does it say what conditions must be met and when you must stop and consult? Is it current? If your director cannot answer those questions quickly, that is information.

Registered Practical Nurses

An RPN is in the same position on authority, and the guideline puts more weight on client selection. Your education is oriented toward clients whose conditions and outcomes are more predictable, so the question of whether this particular client is appropriate for you is a live clinical judgement each time, not a category you settled once.

Nurse Practitioners

An NP is an autonomous provider and can assess, diagnose, prescribe, issue orders and author directives. The guideline therefore lands on you twice: once as a practitioner, and once as the person other nurses are relying on.

If you author directives, the guideline is effectively a specification for them. It is also a reminder that authorship is ongoing. A directive is only live while the authorizing provider stands behind it, which means reviewing it, revising it when the nurse’s practice changes, and being reachable when a client does not fit.

One related change worth noting, because it affects how NPs are described: on 1 July 2026 CNO moved to a single Nurse Practitioner classification. The specialty certificates, Primary Health Care, Paediatrics and Adult, stopped being protected titles, and existing NPs transitioned without further examinations. An NP who trained in primary health care is still that, but the correct current styling is simply Nurse Practitioner.

Consent and emergency response

Consent for an elective cosmetic procedure carries a higher bar than consent for treatment somebody needs.

There is no medical necessity to fall back on. The client is paying, they have usually formed an expectation from photographs, and their satisfaction is bound up with an outcome you cannot fully control. The guideline expects the conversation to cover realistic outcomes, the foreseeable risks including the rare serious ones, alternatives, cost, and doing nothing at all. It expects the client to have capacity and to not be under pressure. Record the conversation, not merely the signature.

Emergency response is expected to be proportionate to the risk you have introduced. The practical test is uncomfortable but useful: if the worst foreseeable complication of the treatment you are about to perform happened right now, what would you do in the next ninety seconds, with what, and who would you call? If the answer involves fetching something from another building or looking something up, you are not prepared, and the fix is not a certificate.

Advertising: what a nurse may not say

The guideline places real limits on how a nurse advertises aesthetic services, and those limits bind you personally, not just your employer.

You may not guarantee an outcome. You may not use comparative claims that position you as better than other practitioners, which removes the entire category of best injector, top clinic and leading provider. You may not create a misleading impression of your qualifications or your authority, which is where the phrase certified injector becomes a problem: it implies a certification that no Ontario body issues. And you may not use the language of clinical necessity to sell an elective service.

This applies to what you post as much as to what you print. A nurse’s social media account is advertising.

The open question

CNO has said it continues to consult with health system partners and to actively review how authorizing mechanisms, including directives and delegation, are used in this area of practice.

That sentence is the most important thing on this page for anyone planning a business. It means the position is not settled. The current arrangement, in which most aesthetic nursing runs on directives authored by an authorized provider, is under active review by the regulator, and the outcome of that review is not knowable from here.

It is worth being precise about the two mechanisms, because the review names both. A directive authorizes you to perform a controlled act that is already within your profession’s scope, once the conditions are met. Delegation transfers an act from outside your profession’s scope to you. For a nurse injecting, both controlled acts are already within nursing scope, so the ordinary route is a directive.

The practical response is not to guess. It is to keep your documents in a state where they can be reissued quickly, to work with an authorizing provider who is watching for changes, and to be sceptical of anyone selling you a permanent solution to a question the College has openly said it is still considering.

Where to check, and where we fit

CNO Practice Support answers practice questions from nurses directly, and for anything specific to your own situation that is the right place to ask.

Obligations also differ by regulator. A physician who delegates is governed by the College of Physicians and Surgeons of Ontario; a Nurse Practitioner who authorizes is governed by CNO. Do not assume that a requirement you read about one applies to the other. Confirm the specifics rather than inferring them.
