Key takeaways
  • Guardianship covers personal decisions such as health care and where the adult lives, while trusteeship covers finances, and you can apply for both at once.
  • The Court may appoint a guardian or trustee only if satisfied the adult lacks capacity for those decisions, and a guardianship order also requires that less intrusive alternatives would not likely be effective.
  • A guardianship application usually takes about 6 months from ready paperwork to a Court decision.

When an adult can no longer make decisions safely, families often hear the words guardian and trustee used together. They are different roles under the Adult Guardianship and Trusteeship Act, and each covers a different part of the person's life.

This article compares the two, explains who can apply and how, and points out alternatives that may avoid court. A lawyer can help you decide which fits your situation.

This article covers the law of Alberta.

The core difference

Guardianship covers personal decisions such as health care, where the adult lives, who they associate with, education or training, social activities, employment and legal proceedings. A guardian cannot make financial decisions or consent to sterilization. Trusteeship covers finances, and you can apply for both at once.

The Court grants a guardian authority only over the personal matters it considers necessary. The guardian may then act, decide and give consents on those matters.

Who can apply and how

Any interested person may apply for a guardianship order, including the Public Guardian, the Public Trustee, and anyone 18 or older concerned for the adult's welfare. An interested person may also apply for a trusteeship order. The Court may make a trusteeship order for an adult ordinarily resident in Alberta.

Applicants choose a desk application or an application with a hearing. A desk application suits cases where no one is expected to disagree and it is not time-sensitive, while a hearing suits cases where someone may disagree or time matters. Notice of a guardianship application must be personally served on the adult, though the Court may dispense with service if notifying the adult would be harmful to the adult. Notice of a trusteeship application must also be personally served on the adult, but that rule is subject to an exception in s 46(4) of the Act, so it is worth confirming with a lawyer how it applies to your situation.

Time, cost and urgent situations

A guardianship application usually takes about 6 months from submission of ready paperwork until the Court decides. The court filing fee is up to $300, and other costs include the capacity assessment, any legal fees and a background check fee. A Hardship Application for Costs Against the Crown is available.

For an urgent guardianship order where there is immediate risk, the Court may appoint a temporary guardian for up to 90 days, and a regular application is needed if guardianship is still required afterwards. For an urgent trusteeship order, the adult must be in immediate danger of serious financial loss, and a temporary trustee cannot sell, dispose of or encumber the property.

Duties and oversight

Guardians must act in the adult's best interest, act diligently and in good faith, encourage independence, use the least intrusive effective approach, inform the adult of important decisions, keep records and protect personal information.

A trustee must act in the adult's best interests and with the care, skill and diligence of a reasonably prudent person. When directed, the trustee must submit accounts for Court examination and approval. A review can be sought at any time, and the Court shall terminate a trusteeship order if satisfied the person no longer needs a trustee.

Alternatives and what to do next

The Alberta guidance says to consider alternatives first. For personal matters these include supported decision-making, a personal directive, specific decision-making and co-decision-making. For finances they include informal trusteeship or an enduring power of attorney. The Court may not give a guardian authority that an agent can exercise under a personal directive unless the agent's authority is terminated, and where a directive has clear and relevant instructions, the guardian must follow them. An enduring power of attorney ends when a trusteeship order is granted in respect of the donor.

Frequently asked questions

Can one person be both guardian and trustee?

You can apply for guardianship and trusteeship at once. Who the Court appoints depends on the facts and on who meets the requirements for each role.

Can a guardian manage the adult's money?

No. A guardian cannot make financial decisions. Finances fall under trusteeship.

What happens if no family member can act?

If no one is willing or available, the Public Guardian may be appointed guardian, but only in limited circumstances, and the OPGT may become guardian when that is in the adult's best interests. The Public Trustee may be appointed trustee only in the circumstances listed in s 50(1), and the OPGT acts as trustee if no one else is available.

Can an order end if the adult recovers?

A review can be sought at any time, including when the adult's capacity changes. A capacity assessment may be required if termination of a trusteeship is sought after regained capacity.
