How to Appoint a Proxy in Prince Edward Island

A healthcare proxy in PEI is the person who makes medical decisions on your behalf when you can no longer communicate your own wishes. The appointment is made inside your Health Care Directive under the Consent to Treatment and Health Care Directives Act — but PEI adds a step that most other provinces don't require, and skipping it renders the entire appointment void.

The Mandatory Acceptance Signature

In PEI, naming someone as your proxy on paper isn't enough. The proxy must physically sign the Health Care Directive to accept the appointment. This isn't a recommendation or a best practice — it's a hard statutory requirement. If the proxy doesn't sign, their appointment is legally invalid.

This catches families off guard regularly. A maker might complete their directive, name their adult daughter as proxy, file the document with their doctor, and assume the job is done. But if the daughter never signed the directive, she has no legal authority to make medical decisions when the time comes. The hospital would default to PEI's statutory hierarchy instead.

Who Can Serve as a Proxy

The eligibility bar is straightforward:

• Age: At least 16 years old (matching the Health Care Directive's minimum creation age)
• Willingness: Must agree to the appointment in writing before you lose capacity — in practice, by signing the directive
• Capacity: Must be capable of making the treatment decisions they will be asked to make

The 10-year criminal-offence bar in the Powers of Attorney and Personal Directives Act applies to financial Attorneys and personal-care Agents, not to a healthcare Proxy appointed under the Consent to Treatment and Health Care Directives Act.

You can appoint multiple alternate proxies in case your first choice is unavailable, unwilling, or unable to act when the time comes. Each alternate must also accept the appointment in writing.

Choosing the Right Person

The legal requirements are simple, but the practical decision takes more thought. Consider these factors:

Geographic proximity. An out-of-province proxy is legally valid, but a medical crisis at the Queen Elizabeth Hospital in Charlottetown or Prince County Hospital in Summerside may require an immediate in-person decision. If your first-choice proxy lives in Toronto or Calgary, name a local alternate who can respond within hours.

Emotional resilience. Your proxy may need to authorize the withdrawal of treatment or confirm a comfort-care-only approach. Not everyone can make that call under pressure, regardless of how much they care about you.

Understanding of your values. The best proxy isn't necessarily your closest relative — it's the person who genuinely understands what quality of life means to you and will advocate for your preferences even if other family members disagree.

Willingness to disagree with family. If your proxy chooses comfort care and your siblings want aggressive treatment, the proxy's decision has legal authority. Choose someone who can handle that conflict.

What Happens If You Don't Appoint a Proxy

If you become incapable of making medical decisions and you haven't appointed a proxy — or your proxy appointment is invalid because they never accepted in writing — PEI law establishes a default hierarchy of substitute decision-makers under the Consent to Treatment and Health Care Directives Act. After a named proxy, the clinician proceeds in this order:

1. A guardian, if they have authority to give or refuse consent to treatment
2. Spouse (this does not include a person living separate and apart under the Divorce Act)
3. A son or daughter, or a parent, or a person who has assumed parental authority (these sit in the same class)
4. A brother or sister
5. A trusted friend with close knowledge of the patient's wishes
6. Any other relative

A later class is used only if the higher-ranking person is unavailable, unwilling, or themselves incapable. If no one on that list is available, willing, and capable — or if people in the same class disagree about treatment — the Public Guardian and Trustee may make the decision. That adds delay, involves a government office in your family's medical decisions, and can result in fees charged against your property.

Appointing a proxy eliminates this chain entirely. One person has clear legal authority, and the statutory hierarchy never activates.

The Proxy's Decision-Making Standard

Your proxy isn't free to impose their own preferences. PEI law requires the proxy to follow the instructions you've written in your Health Care Directive. If your directive doesn't address a specific situation, the proxy must make the decision they believe you would have made, based on your known wishes, values, and beliefs.

This is why the directive itself matters so much — a vague or incomplete directive gives your proxy less guidance and more room for uncertainty. Specific instructions about resuscitation, ventilation, artificial nutrition, and organ donation give your proxy a clear framework to work from.

How to Formalize the Appointment

1. Draft your Health Care Directive with your proxy's full name and contact information
2. Name alternate proxies in order of succession
3. Have each proxy and alternate physically sign the directive to accept — this is non-negotiable
4. Deliver a copy to each proxy so they have it on hand during an emergency
5. Give a copy to your family physician and ask for it to be entered into your clinical EMR file
