Dementia Power of Attorney Alberta: What to Do Before and After a Diagnosis

The Capacity Window Is Shorter Than Families Think

A dementia diagnosis does not immediately mean a parent lacks legal capacity. Alberta law presumes every adult has capacity until there are reasonable grounds to believe otherwise. In the early stages of Alzheimer's or vascular dementia, many parents can still understand what an Enduring Power of Attorney (EPA) and Personal Directive are, appreciate the consequences of signing them, and make informed choices about who should manage their affairs.

That window closes gradually — and unpredictably. Some parents lose capacity steadily over months. Others have sudden drops after a hospitalization, a urinary tract infection, or a medication change. Families who plan to "get to it next month" often discover the window has already shut.

Once a parent cannot understand and appreciate the nature and consequences of an EPA or PD, they cannot legally sign one. Alberta law is clear on this. No amount of family agreement, good intentions, or urgency changes the requirement. The document is invalid if the donor lacked capacity at the time of signing.

What "Capacity to Sign" Actually Means

The threshold for signing an EPA or PD is not the same as the threshold for managing daily life. A parent who cannot balance a chequebook might still have the capacity to understand that they are appointing someone to manage their finances and appreciate what that means.

The legal test is decision-specific: can the person understand the information relevant to this particular decision, and can they appreciate the reasonably foreseeable consequences? A physician assessing capacity for EPA signing evaluates whether the parent understands:

• What property and finances they own
• What an EPA does — that it gives someone else authority over those finances
• Who they are appointing and what authority that person will have
• What risks exist if the attorney misuses that authority
• That they can revoke the EPA while they retain capacity

If the physician is satisfied on these points, the parent can sign. A dementia diagnosis alone does not disqualify them.

After the Window Closes

When a parent with dementia crosses the capacity threshold, the family loses the ability to set up proactive planning documents. What remains:

For immediate medical decisions: The Section 96 Specific Decision-Making pathway under the AGTA lets a healthcare provider select a relative from a ranked statutory hierarchy to make a single healthcare decision or authorize a temporary care home placement. No court involved, but authority is limited to one decision at a time.

For ongoing comprehensive authority: The family must apply to the Court of King's Bench for a guardianship order (personal decisions) and/or trusteeship order (financial decisions) under the AGTA. This requires a formal capacity assessment (Form 4, up to $700 for combined), a $300 court filing fee, and an OPGT Review Officer investigation. Standard processing for an uncontested desk application: eight to twelve months.

During that eight-to-twelve-month window, the parent's bank accounts are effectively frozen to the family. Bills go unpaid. The care home does not get paid. The mortgage falls behind. This is the concrete cost of missing the planning window.

The Early-Stage Action Plan

If your parent has received an early-stage dementia diagnosis and still retains capacity, the priority list is short and urgent:

1. Execute an Enduring Power of Attorney. Name a trusted attorney for financial decisions. Include explicit banking clauses, a Land Titles clause if property is involved, and a reimbursement clause allowing the attorney to cover care costs from the donor's funds.

2. Execute a Personal Directive. Name an agent for healthcare and personal decisions. Specify treatment preferences, care home preferences, and end-of-life instructions while the parent can articulate them.

3. Register the EPA at the bank. Walk into the bank with the parent while they can confirm their wishes. Have the compliance department verify and upload the document before any crisis occurs.

4. Register the PD with the OPGT. Free registration lets physicians confirm that a PD exists and contact the agent(s) in an emergency.

5. Set up the Green Sleeve. Work with the family physician to complete a Goals of Care Designation conversation and assemble the Green Sleeve with the GCD order, a PD copy, and the ACP tracking record.

6. Review the triggering mechanism. If the EPA is springing, confirm that the named declarant is available and willing to act. If the EPA names the family physician and that physician is approaching retirement, update the document now.

Managing an Existing EPA During Dementia Progression

If your parent already has an EPA and PD in place, the documents do not expire merely because dementia progresses, but review the practical details as circumstances change:

• Confirm the springing EPA activation process is clear and the declarant is available
• Update the bank if the EPA was registered years ago — confirm the document is still on file and the branch has current contact information for the attorney
• Review the Personal Directive agent's availability — if the named agent has moved provinces or become ill, the parent may still have capacity to appoint an alternate
• Keep financial records meticulously — the attorney has a legal duty to act in the donor's best interest, and clear records protect against accusations of financial abuse from other family members

The Alberta Power of Attorney & Personal Directive Kit covers both the initial execution process and the activation protocol, with specific attention to the capacity assessment procedures that apply when a springing EPA needs to be triggered.
