Short answer

A medical director agreement should set out what orders and directives the physician or nurse practitioner will issue, who assesses each client and when, how they supervise and stay available, and how adverse events, records, advertising and payment are handled. It also has to fit the director's own college rules: in Ontario, CPSO's Delegation of Controlled Acts policy for physicians and CNO's standards for nurse practitioners and the nurses who carry out their orders.

“Medical director” isn’t a licence category in Ontario. It’s a title clinics give to the physician or nurse practitioner whose authority lets nurses and other staff perform treatments that involve controlled acts. CNO’s Aesthetic Services guideline treats it as a practice-setting title, like “nurse injector”. The agreement should describe what that person actually does.

What does a medical director do in an Ontario med spa?

They are the authorizing provider. Registered nurses and registered practical nurses can perform procedures such as cosmetic injections only when the procedure is ordered by an authorized person, which under section 5 of the Nursing Act, 1991 includes a physician and a nurse practitioner. Physicians can also delegate controlled acts to people who aren’t authorized to perform them, including unregulated staff, under section 27 of the Regulated Health Professions Act, 1991 and CPSO’s Delegation of Controlled Acts policy.

Order, directive or delegation?

MechanismWhat it isTypical use in a med spa
Direct orderWritten or verbal instructions for a specific client, for a specific treatmentA physician or NP assesses a client and orders a specific treatment
DirectiveA written order that applies to any client who meets set conditionsStanding instructions for a defined treatment, with criteria and contraindications
DelegationTemporary transfer of authority to perform a controlled act to someone not authorized to do itStrict college requirements apply, and CNO is reviewing its use in aesthetics

CNO’s orders, directives and delegation FAQ explains that when a nurse implements a directive, the nurse assesses whether the client meets its criteria. CNO’s guideline says an authorizing mechanism must be clear, complete and appropriate, with appropriateness based on an assessment of the client’s health history, contraindications and a physical assessment. CNO has also said it is actively reviewing how directives and delegation are used in aesthetics, so the agreement should require both sides to follow changes when they take effect.

What must a medical directive include?

For physicians, CPSO’s policy lists what a medical directive must contain:

  • The name and description of the procedure, in enough detail for safe implementation.
  • The specific clinical conditions the patient must meet, and any situational circumstances that must exist.
  • A complete list of contraindications.
  • Who is authorized to implement it.
  • The name and signature of the authorizing physician and the date it takes effect.
  • Any administrative approvals, with dates.

How involved does the medical director have to be?

More than a name on the door. When a physician delegates a controlled act, CPSO’s policy requires them to:

  • Delegate only in an existing or anticipated physician-patient relationship, and clinically assess each new patient before delegating or, where that isn’t possible, within two business days of the delegate starting the controlled act, outside listed exceptions.
  • Be physically onsite to supervise, unless the risk is low or another physician who can support the delegate is onsite, and otherwise be available to help on short notice.
  • Make sure patients know who the delegating physician is, and can ask to speak to them.
  • Have protocols for adverse events and an ongoing system to monitor delegates, including reviewing records.
  • Not delegate when the main reasons are monetary gain or convenience.

For nurse practitioners, CNO’s guideline says NPs should be actively involved with the team carrying out their aesthetic orders, decide when their direct involvement or supervision is needed, assess whether remote or virtual prescribing is suitable, and be able to manage adverse outcomes.

What clauses should the agreement have?

Supervision and availabilityOnsite days, response times, and backup cover when the director is away
Staff competenceHow injectors’ training and competence are confirmed before they act
Products and equipmentHealth Canada-approved products only, with storage and handling rules

How should a medical director be paid?

Write it down, and have the director check it with their college and insurer. The Medicine Act regulations make it professional misconduct for a physician to share fees with a person who referred a patient, or to accept a rebate or commission for a referral (O. Reg. 856/93). They also treat some arrangements as conflicts of interest, such as renting premises to or from certain suppliers unless the rent is normal for the area and isn’t tied to the volume of business or to referrals, and selling drugs to patients at a profit outside narrow exceptions (O. Reg. 114/94, s. 16). CNO’s guideline also warns nurses against incentives tied to selling volumes of specific products or injections.

What about the director’s name in ads?

Physicians must follow rules on how their name appears in advertising: under section 9 of O. Reg. 114/94, it must be followed by their recognized specialty or the title “General Practitioner”. CNO’s guideline says nurses’ aesthetic advertising should include the name of their authorizing provider or medical director. Agree in the contract who approves marketing that names the director.
