Yukon Adult Guardianship: Court Process, Costs, and How to Apply

When Guardianship Becomes Necessary

Court-ordered guardianship is what happens when nobody planned ahead. If an adult loses mental capacity — through dementia, a traumatic brain injury, or a severe stroke — and no enduring power of attorney (EPA) or Advance Directive exists, their family cannot legally manage their finances or make healthcare decisions on their behalf. The only path forward is applying to the Supreme Court of Yukon for a guardianship order under Part 3 of the Decision Making, Support and Protection to Adults Act.

It's slow, expensive, and public. The court file becomes part of the record. Multiple family members must be served with formal notice. A professional medical assessment must be paid for. And at the end, the guardian's authority is narrower and more closely supervised than an EPA attorney's would have been.

This is why every estate planning guide emphasizes doing the paperwork while capacity still exists. But not everyone gets that chance.

The Application Process

To apply for guardianship in Yukon, a family member or close friend must file a formal application package with the Supreme Court of Yukon in Whitehorse. Here's what the package requires:

Form 3 — Application for Guardianship. The core application identifying the proposed guardian, the adult, and the type of guardianship requested (personal, financial, or both).

Form 4 — Affidavit of Applicant. A sworn statement from the person applying, setting out their relationship to the adult, why guardianship is needed, and why they're an appropriate guardian.

Form 5 — Affidavit of Personal Knowledge. A supporting affidavit from someone who knows the adult personally, confirming their current circumstances and the need for a guardian.

Form 6 — Incapability Assessment Report. A detailed medical and functional assessment completed by a qualified healthcare provider. This is not a standard doctor's note — it must evaluate the adult's ability to understand and appreciate the decisions they face. Getting this assessment done is often the most expensive and time-consuming part of the process.

Form 7 — Preliminary Guardian Plan. A proposed plan outlining how the guardian intends to manage the adult's personal and financial affairs, where the adult will live, and how their wishes and values will be incorporated.

Form 8 — Consent of Proposed Guardian. The proposed guardian's signed consent to take on the role and its legal obligations.

All forms are available from the Public Guardian and Trustee's office or the Yukon.ca website.

Costs

The financial burden of guardianship breaks down into several layers:

Court filing fee. $140 to commence a proceeding in the Supreme Court of Yukon (no fee for estates under $25,000).

Incapability Assessment Report. This varies significantly depending on who conducts it and where the adult lives. In Whitehorse, assessments typically cost several hundred dollars. For adults in remote communities, the assessor may need to travel or the adult may need to travel to Whitehorse, adding transportation and accommodation costs.

Legal representation. While not strictly required, most families retain a lawyer to prepare the application. Legal fees for a straightforward guardianship application in Whitehorse typically run $2,000–$5,000 or more, depending on complexity and whether any family members contest the appointment.

Ongoing guardian fees. Under OIC 2005/78, a private guardian's compensation is capped at 2.5% of money received, 2.5% of money disbursed, and 0.5% annually for ongoing management. These fees come out of the adult's estate.

If the Public Guardian and Trustee (PGT) serves as guardian — either because no family member is willing or able, or because the court determines a private guardian is unsuitable — the PGT charges its own fee schedule under OIC 2005/83. The PGT's minimum administrative fee for estate management is $1,500.

The Public Guardian and Trustee as Guardian of Last Resort

The PGT steps in when no one else will or can. This happens more often in the Yukon than in larger provinces — the territory's small, dispersed population means some adults genuinely have no family members available to serve.

The PGT's role as "guardian of last resort" means they will assume responsibility, but their mandate is institutional rather than personal. They manage the adult's finances according to statutory obligations, pay bills, protect assets, and report to the court. They do not provide the kind of individualized attention a family guardian would.

For families with an elderly relative showing early signs of cognitive decline, the cost and complexity of guardianship is the strongest argument for creating an EPA now. A valid EPA executed while capacity exists avoids the court process entirely — no filing fees, no assessment reports, no public record.

Emergency Financial Protection (the 60-Day Bridge)

If a guardianship application is in progress but the adult's bills need paying immediately, there's a short-term solution: the Certificate of Need for Financial Protection under Section 61 of the Care Consent Act.

A healthcare provider completes Form 2, certifying that the adult can no longer manage their financial affairs. The form is submitted directly to the PGT, who then assumes temporary statutory authority over the adult's finances for up to 60 days. This bridge buys time to complete the full guardianship application or, if capacity can be restored, to execute an EPA.

The 60-day window is strict. If the guardianship order isn't in place by the time the Certificate expires, the PGT's temporary authority ends and the family is back where they started.

An EPA is simpler, cheaper, and keeps decision-making within the family. The Yukon Power of Attorney Kit helps you set one up correctly — before the guardianship process becomes the only option.
