Advance Health Care Directive in Newfoundland and Labrador

What an Advance Health Care Directive Does in NL

An Advance Health Care Directive (AHCD) is your legal voice for medical decisions when you can no longer speak for yourself. In Newfoundland and Labrador, it serves two distinct functions under the Advance Health Care Directives Act (SNL 1995, c. A-4.1):

1. It appoints a Substitute Decision Maker (SDM) — the person who will make healthcare decisions on your behalf
2. It records your treatment preferences — specific instructions about the care you want or do not want

The AHCD was one of the earliest such statutes in Canada, giving Newfoundland a structured legal pathway for healthcare autonomy that many other provinces adopted later.

Critically, an AHCD covers healthcare decisions only. It does not give anyone authority over your bank accounts, property, or financial affairs. That requires a separate Enduring Power of Attorney — the two documents work in parallel but under entirely different legislation.

Who Can Make an AHCD

The threshold for creating an AHCD is lower than for an EPA:

• Age: You can make an AHCD at 16 years of age (compared to 19 for an EPA)
• Capacity: You must be competent at the moment of signing — meaning you understand the nature and consequences of the directive
• SDM requirement: Your appointed SDM must be at least 19 years old

The lower age threshold reflects a deliberate policy choice. A 16-year-old managing a serious illness should be able to document their healthcare preferences and name a trusted adult to carry them out.

The Written Acceptance Rule That Catches Everyone

This is the single most common reason AHCDs fail in Newfoundland and Labrador: the SDM must formally accept their appointment in writing.

Unlike an EPA — where the attorney simply starts acting when the time comes — the AHCD statute requires the SDM to sign an acceptance section in the directive itself. If this section is blank or missing, the appointment is legally void. The hospital will not recognize the SDM's authority, and the medical team will fall back on the statutory default priority list of relatives.

Many families complete the directive, have it properly witnessed, file it away — and never ask the SDM to sign the acceptance. They discover this gap during a medical crisis, at which point the maker may no longer have the capacity to execute a new directive.

Execution Requirements

An AHCD must be signed in the presence of two independent witnesses (one more than the EPA requires). Neither witness can be:

• The appointed SDM
• The SDM's spouse

If the maker cannot physically sign due to a disability, another person can sign on their behalf in the maker's presence. This substitute signer cannot be the SDM or their spouse, and both witnesses must observe the signing.

What Happens Without an AHCD

When a patient loses the ability to make or communicate healthcare decisions and has no AHCD, the attending healthcare professional activates Section 10 of the Act. This triggers a statutory default priority list:

1. Spouse or cohabiting partner (must have lived together in a conjugal relationship for at least one year)
2. Children
3. Parents
4. Siblings
5. Grandchildren
6. Grandparents
7. Uncles and aunts
8. Nephews and nieces
9. Any other relative
10. The healthcare provider themselves

The default proxy must be at least 19, willing to take on the role, and must have had contact with the patient within the preceding 12 months. If the contact requirement cannot be met, an urgent court application is required to waive it.

This system works tolerably well for patients with a clear, available, willing next-of-kin. It breaks down when the highest-ranking relative is unavailable, estranged, or disagrees with other family members about care decisions. An AHCD eliminates this friction by naming the decision-maker directly.

What the SDM Can and Cannot Do

The SDM's authority is structured in a specific hierarchy:

1. Follow the directive's explicit instructions first — if the AHCD says "no ventilator after 14 days," the SDM must honour that
2. Apply the maker's known values and wishes when the directive is silent on a specific treatment — previous conversations, religious beliefs, and expressed preferences guide the decision
3. Use the best-interests standard only when the maker's wishes are completely unknown

The SDM cannot consent to:

• Medical Assistance in Dying (MAiD), unless the directive explicitly authorizes it
• Non-medically necessary surgeries like living organ donation, unless explicitly authorized
• Any procedure that is illegal under Canadian law

Revoking or Updating an AHCD

A maker can revoke their AHCD at any time while they still have capacity:

• By executing a newer directive that explicitly revokes all prior versions (signed with two fresh witnesses)
• By drafting a separate signed revocation document, also witnessed by two people
• In an emergency, by physically destroying the document with clear intent to cancel it

Once the maker loses capacity, the directive can no longer be changed by anyone — it stands as written.

The Newfoundland and Labrador Power of Attorney Kit includes the AHCD alongside the EPA, with the mandatory SDM acceptance section built into the document and a separate execution checklist for the two-witness signing process.
