Can Doctors Ignore an Advance Directive in PEI?

The short answer is that a valid PEI Health Care Directive carries real legal authority — but the practical answer is more nuanced. The directive's instructions aren't applied literally by the medical team. They're translated into a clinical framework, and there are specific situations where a doctor may deviate from what you've written.

When the Directive Is Binding

Under the Consent to Treatment and Health Care Directives Act, a Health Care Directive that is properly created, signed, and (if applicable) witnessed is legally valid and must be respected by healthcare practitioners. When you lose the capacity to make medical decisions, the directive and your appointed proxy become the primary authority over your treatment.

A clinical team that ignores a valid directive and provides treatment you've explicitly refused can face legal consequences — this isn't a suggestion or a set of guidelines. It's a statutory framework.

Your directive is strongest when it is specific. Instructions written in Health PEI's own Goals of Care language (R for Resuscitation, M for Medical, C for Comfort) are the easiest for clinical staff to implement because they match the terminology the medical team already uses for treatment orders.

When a Doctor Can Deviate

There are legitimate circumstances where a PEI healthcare provider might not follow a directive exactly as written:

The directive's instructions are ambiguous. "No heroic measures" means different things to different doctors. If the medical team can't determine what you intended, they need to interpret — and interpretation means clinical judgment, not blind compliance. Vague directives give doctors broader discretion, which may not align with what you actually wanted.

The clinical situation wasn't anticipated by the directive. A directive might address terminal cancer but say nothing about a treatable condition that emerges alongside it. If you develop a completely separate, curable medical issue that your directive didn't contemplate, the medical team faces a gap in your instructions.

The proxy is deciding a situation the directive doesn't cover. Your proxy must follow applicable instructions in the directive. If the directive is silent, they follow wishes you expressed while capable that they believe you would still act on. More recent capable wishes can take priority over older written instructions if both the proxy and the health practitioner have satisfactory evidence of those wishes. The proxy cannot simply substitute their own preferences, or decide that your wishes have changed, without that evidence.

Emergency treatment before the directive is located. If you arrive at the emergency department unconscious and no one can locate your directive or contact your proxy, the clinical team will provide standard emergency care (effectively Designation R — full resuscitation) until the directive is found or a substitute decision-maker is identified. This isn't ignoring the directive — it's the practical reality of emergency medicine when no documentation is immediately available.

What Hospitals Cannot Do

A hospital cannot override your directive simply because a family member disagrees with your choices. If you've documented a preference for comfort care (Designation C) and your adult child demands aggressive treatment, the directive and your proxy's authority take precedence over the family member's wishes.

A hospital also cannot refuse to honor a valid directive because they find its instructions ethically uncomfortable. Individual practitioners may have personal objections to certain end-of-life decisions, but the institution's obligation is to follow the directive or arrange for another practitioner who will.

How to Make Your Directive Harder to Ignore

Be specific. Write in R/M/C Goals of Care terms rather than general language. A directive that says "Designation C — comfort care only, no resuscitation, no ICU transfer, no artificial nutrition" leaves almost no room for interpretation.

Get a Goals of Care Designation on file. When your physician translates your directive into a GCD medical order and saves it to the provincial Electronic Medical Record, it becomes an active clinical order — not just a document to be located and interpreted. Emergency responders and hospital staff can access the GCD immediately through the EMR.

Complete a Health PEI Advance Care Planning wallet card. First responders check for these. The card confirms that a directive exists and lists proxy contact information.

Keep copies accessible. A directive on the refrigerator in a clear sleeve, a copy with your family doctor, and a copy with your proxy ensures the document is findable in the situations where it matters most.

Review regularly. A directive written five years ago that names a proxy who has since moved away, or instructions that don't reflect a new diagnosis, gives the medical team reason to question whether the document reflects your current wishes. Reviewing every two years — or after any major health change — keeps it current.
