Does a Power of Attorney Still Work After Death in Ontario?

Families often assume that whoever was managing a loved one's finances while they were alive can simply keep going after death — paying the last bills, closing accounts, handling whatever comes up. It feels practical, and in many households it is exactly what an attorney for property was already doing.

It is also wrong. In Ontario, a power of attorney after death has no legal effect at all. The document that gave someone authority to act stops working the moment the person dies, no matter how broad it was while they were alive.

Understanding exactly when that authority ends — and who picks it up — helps families avoid mistakes made in good faith during an already difficult time.

The Basic Rule

Every power of attorney in Ontario, whether it is a Continuing Power of Attorney for Property or a Power of Attorney for Personal Care, ends automatically on the grantor's death. This is true even if the document says nothing about it, and even if the attorney does not yet know the person has died. Death simply switches the authority off.

From that point forward, the only person with legal authority to deal with the deceased's property is a properly appointed estate trustee — sometimes still called an executor or administrator. That authority comes from the will (if there is one) or from a court appointment (if there is not), never from a power of attorney.

Power of Attorney vs. Estate Trustee

These two roles are easy to confuse because the same family member often ends up filling both — but they are legally distinct, apply at different times, and draw their authority from different sources.

Why This Surprises So Many People

The attorney was often the one closest to the finances

If you held a Continuing Power of Attorney for Property for a parent, you may have been paying their bills, managing their bank account, and handling their affairs for months or years. It feels natural to keep doing that immediately after death — but legally, your authority to act under that document ended the moment they passed away.

Nobody told the bank or the utility company right away

In practice, there is often a short window where an attorney continues making a payment or two before realizing the document no longer applies, simply because institutions have not yet been notified of the death. That does not make it authorized — it just means the gap has not yet been caught.

What Actually Happens Instead

Once someone dies, a will (if there is one) names an estate trustee who must generally apply to the court for a Certificate of Appointment of Estate Trustee before most banks, the land registry, and other institutions will treat them as having authority over the deceased's property. If there is no will, someone eligible under the Estates Act — often the closest next of kin — must apply to be appointed as estate trustee without a will.

Until that appointment happens, no one has clear, documented legal authority to move the deceased's assets. This is one of the main reasons families are often advised to begin the estate trustee application promptly, even though it takes time and cannot be rushed.

What an Attorney Can Reasonably Do in the Immediate Aftermath

While a former attorney cannot deal with the deceased's property after death, a person close to the deceased can generally still take a few practical, non-financial steps while an estate trustee is being appointed:

• [ ] Notify banks, insurers, and government programs (like OAS/CPP) of the death
• [ ] Secure the home and valuable property from loss or damage
• [ ] Locate the original will and any prior powers of attorney
• [ ] Gather account statements and asset information the future estate trustee will need
• [ ] Arrange the funeral, which is generally treated as a priority estate expense

None of this requires — or restores — authority under the old power of attorney. It is simply practical caretaking while the legal process to appoint an estate trustee moves forward.
