What If Family Disagrees with an Advance Directive in Yukon?

Your mother is in Whitehorse General Hospital, unable to communicate. Her Advance Directive says to discontinue life support if she enters a persistent vegetative state. Her proxy — your older brother — is following her instructions. But your sister wants "everything done" and is demanding that the doctors ignore the directive. The medical team is caught in the middle, and nobody knows whose voice carries.

Family disagreements during medical crises are emotionally devastating and legally messy. Yukon law provides clear rules about who has authority — but those rules only help if everyone understands them.

The Proxy Has Legal Authority

Under the Care Consent Act, the appointed proxy has the legal right to make healthcare decisions when the maker lacks capacity. This authority is not shared with the family at large. The proxy's decision — based on the maker's documented wishes — takes precedence over the opinions of siblings, parents, adult children, or anyone else.

This is the entire point of naming a proxy. Without one, healthcare decisions fall to the statutory default hierarchy (guardian, then spouse, then adult children, then parents, then siblings), which can create exactly the kind of multi-party disagreement that tears families apart. With a named proxy, the decision-making authority is clear.

The proxy must follow the maker's last known capable wishes as documented in the Advance Directive. If those wishes do not address the specific situation, the proxy follows the maker's known values and beliefs. Only as a last resort does the proxy use their own judgment of the maker's best interests.

What Family Members Can Actually Do

Family members who disagree with the proxy's decisions have limited but real options under Yukon law:

Raise concerns with the healthcare provider. A family member can speak with the medical team about their concerns. If the provider believes the proxy is not following the maker's documented wishes, they can challenge the proxy's decision.

Refer to the Capability and Consent Board. Either a healthcare provider or an interested party can refer a dispute to the Capability and Consent Board. The Board reviews capacity assessments, examines the directive, hears from all parties, and makes a binding decision. This is faster and less expensive than going to court.

Apply to the Supreme Court of Yukon. In extreme cases — if a family member believes the proxy was appointed under duress, lacks capacity themselves, or is acting against the maker's clear wishes for personal gain — they can apply to the court for intervention. This is the most expensive and time-consuming option and is typically reserved for cases involving suspected abuse or fraud.

What family members cannot do is simply overrule the proxy. Emotional intensity does not create legal authority. A sibling's belief that "Mom wouldn't really want that" does not override a signed directive that says otherwise.

Why These Disputes Happen

Most family conflicts around advance directives stem from one of three causes:

The family was not part of the planning conversation. When someone writes a directive in private and only the proxy knows the details, other family members feel blindsided during a crisis. They may genuinely believe the directive does not reflect the maker's "real" wishes because they never heard those wishes expressed.

Grief distorts judgment. Facing the loss of a parent or spouse can make family members fight for aggressive treatment even when the patient explicitly refused it. The desire to keep someone alive can overwhelm the intellectual understanding that the patient chose differently.

The directive is ambiguous. Vague instructions like "no extraordinary measures" leave room for interpretation. One family member reads it as "no CPR," another reads it as "no experimental treatments." Specific, scenario-based language in the directive prevents this.

How to Prevent Disputes Before They Start

The most effective protection is transparency during the planning phase:

Include the family in the conversation. You do not need everyone's agreement, but discussing your values and preferences openly reduces the shock factor. When your sister has heard you say — in your own words, while healthy — "I would never want to be kept alive on machines," she is less likely to fight the directive later.

Be specific in the document. Name exact interventions you accept or refuse. Address the scenarios that matter to your family — terminal illness, persistent vegetative state, advanced dementia, traumatic brain injury. Leave as little interpretive space as possible.

Explain your proxy choice. If you chose one child over another, explain your reasoning. "I chose [name] because they can handle hard decisions under pressure, not because I love them more" can prevent sibling resentment from becoming a legal dispute.

Give everyone copies. When all family members have read the directive, nobody can claim they did not know what it said.
