This guide is general information, not medical advice. Your provider should assess you and explain the options and risks that apply to you.
What it is
Dermal fillers are injectable gels. Most are made of hyaluronic acid, a substance that occurs naturally in the skin. Clinics use them to add volume or change shape in areas such as the lips, cheeks, chin, jawline or under the eyes.
In Canada, fillers are regulated as medical devices and must be licensed by Health Canada. Health Canada has said that needle-free “hyaluron pen” devices, which push filler into the skin under pressure, are not authorized in Canada.
Who can perform it in Ontario
Filler injections involve controlled acts under Ontario’s Regulated Health Professions Act. Physicians (CPSO) and nurse practitioners (CNO) can assess and inject.
Registered nurses (RN) and registered practical nurses (RPN) can give these injections only when a physician or nurse practitioner has authorized it. From 1 March 2027, the College of Nurses of Ontario requires a client-specific order for each patient, issued after the authorizing provider has assessed you in person or by video and set a plan of care. Read what changes in 2027.
- Dentists in Ontario can’t inject fillers outside the mouth for cosmetic reasons (RCDSO position).
- Estheticians and laser technicians can’t inject fillers.
Ask for the injector’s full name and registration number, and look them up yourself on the public register: the CPSO register (opens in a new tab) for physicians and the CNO register (opens in a new tab) for nurses and nurse practitioners.
Typical GTA price range

- Clinic-reported, from 12 clinics.
Most GTA clinics price fillers per syringe, often 1 mL. How many syringes you need depends on the area and what you discuss at your consultation.
Ask whether the price includes a review visit, and whether dissolving filler, if ever needed, is charged separately.
Sessions and maintenance
A treatment is often a single appointment, sometimes with a review a few weeks later. Hyaluronic acid fillers break down in the body over time. How long they last varies with the product, the area and the person, so ask your provider what to expect.
Common side effects and risks
Your provider should explain the risks that apply to you before you consent. Commonly reported effects include:
- Swelling, bruising, redness or tenderness, often for a few days.
- Small lumps or unevenness.
- Less commonly, infection, or filler moving from where it was placed.
Rarely, filler can block a blood vessel. That can damage the skin and, very rarely, affect eyesight, and needs urgent treatment. Ask what the clinic would do if it happened, and whether it keeps the medicine that dissolves hyaluronic acid filler on site.
Questions to ask at your consultation
- Who will inject me, and what is their registration number?
- If a nurse is injecting, who is the authorizing physician or nurse practitioner, and will they assess me first?
- Which filler will you use, and is it licensed by Health Canada?
- How many syringes do you expect, and what will the total be, including the consultation fee?
- What would you do if filler blocked a blood vessel? Do you keep the dissolving medicine here?
- How do I reach you after my treatment, including after hours?
A clinic that welcomes these questions is easier to trust. You can take this list with you.
