Power of Attorney vs Executor: Who Can Sell an Ontario Home?

By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 10 September 2026 · 10 min read — who can lawfully sign to sell an Ontario home, how a power of attorney differs from an estate trustee, what a lawyer will want to see, and the failure that stops sales mid-transaction.

This is the single most misunderstood point in Ontario residential real estate, and it costs families real money every year. The two roles look similar from the outside — someone other than the owner is signing for the house — and they are not similar at all.

Before anything else: I am a licensed real estate broker, not a lawyer. Everything below is general background so you know what questions to ask. Powers of attorney, capacity and estate authority are legal matters governed by Ontario legislation and by the wording of the specific document in front of you. Do not act on this page. Retain a lawyer, and do it before you sign a listing agreement, not after an offer lands.

What is the actual difference?

An attorney for property is someone the owner appointed, in writing, while the owner had capacity, to handle their property and finances. The owner is called the grantor. The attorney is not a lawyer — the word here means “someone appointed to act”, and it is usually an adult child or a spouse.

An estate trustee — the older word is executor — is the person named in the will, or appointed by the court, to administer the estate of someone who has died.

The dividing line is death. Everything the attorney can do, they can do only while the grantor is alive. Everything the estate trustee can do, they can do only once the grantor has died and, usually, once the court has confirmed their appointment. The same person is often named in both roles, which is exactly why families blur them — but the authority does not carry over. It stops, and a different authority starts.

What is a continuing power of attorney for property?

Ontario recognises two shapes of power of attorney for property, and the difference matters enormously in a real estate sale.

A continuing power of attorney for property is one that says, in effect, that it continues to be effective if the grantor later becomes mentally incapable of managing property. That is the document families rely on when a parent develops dementia. It is the one that lets a sale happen when the owner can no longer make the decision themselves.

A non-continuing power of attorney does not survive incapacity. It is the kind you might sign because you will be out of the country for three months and need someone to handle a specific matter. If the grantor loses capacity, it ends.

There is a third document people confuse with both: a power of attorney for personal care, which covers health care, housing arrangements, nutrition and safety. It is about the person, not the property. It does not authorise anyone to sell a house. I have sat across from families holding a personal care document and believing they were ready to list. They were not.

Only the lawyer can tell you which document you are holding, whether it was validly made, whether it has been revoked, whether the grantor appointed more than one attorney, and if so whether they must act jointly (all of them sign) or jointly and severally (any one can sign). Those clauses decide who has to be at the table on offer night.

Does the owner have to be incapable before the attorney can act?

Not necessarily, and this is where I most often see well-meaning families go wrong in the other direction.

A power of attorney for property can, depending on its wording, be effective as soon as it is signed — it does not always wait for incapacity. Some documents contain a condition that has to be met, sometimes a capacity assessment, before the attorney may act. Read the document; or rather, have the lawyer read it.

But here is the part that matters more than the legal mechanics. If the owner still has capacity to make the decision, the decision is theirs. An attorney does not get to decide that mum should sell because the stairs worry the family. The attorney’s duty is to act in the grantor’s best interest, to encourage the grantor to participate in decisions to the extent they can, to consult with supportive family and friends, and to keep proper accounts of everything done with the grantor’s money. That is a fiduciary standard, and it is enforceable.

As a broker, my practical test is simple. If the owner can meet me, understand what selling means and tell me what they want, then the owner is my client and the conversation is with them, with family present if they wish. If they cannot, the attorney acts — and I want the lawyer’s confirmation of that in the file before I take a listing.

Why is the family home treated more carefully than other assets?

Because it is usually the largest asset, because it is often the subject of a specific gift in the will, and because selling it can permanently change where a person lives.

Three practical points:

• A sale can affect who inherits what. If the will leaves “my house at such-and-such an address” to one child and the residue to another, an attorney selling that house during the owner’s lifetime converts a specific gift into cash in the residue. Ontario law contains protections aimed at this problem so that the intended beneficiary is not simply written out, but the mechanics are legal and fact-specific. Raise it with the lawyer before the house is listed, not after it closes.
• Where the person is going to live has to be settled first. Selling the home of a living person who has nowhere confirmed to go is not a real estate problem; it is a care problem that produces a real estate emergency.
• Spousal rights can apply. Ontario gives a spouse rights in a matrimonial home that can require consent to a sale. Whether a property is a matrimonial home is a legal question. Ask it early.

What will the lawyer and the land registry office want to see?

Ontario land is registered electronically and the transfer is signed and registered by lawyers, not by you at a counter. What that means in practice is that the authority to sign has to satisfy the buyer’s lawyer, the seller’s lawyer and, where a mortgage is involved, the lender. Expect, in a power of attorney sale:

• The original power of attorney document, or a copy in the form the lawyer requires. Find it before you list. Hunting for it after a firm deal is signed is how closings get extended.
• Confirmation that the document is continuing, if the grantor is incapable.
• Evidence, typically by sworn declaration, that the grantor is alive at the time of the transaction and that the power of attorney has not been revoked.
• Where the document names more than one attorney, confirmation of whether they act jointly or severally, and signatures from whoever must sign.
• Identification of the attorney, and the usual identity verification every party goes through.

In an estate sale the list is different: the will, the death certificate, and commonly the certificate of appointment of estate trustee. There is a fuller walk-through of that side in what an executor selling a home in Ontario actually has to do.

If the property is a condominium, one thing is refreshingly fixed either way: the corporation must produce the status certificate within 10 days of a written request and payment, and the fee is capped at $100 including HST.

What if there is no power of attorney and the owner has lost capacity?

Then nobody can simply sign, and the family cannot fix it themselves. A power of attorney can only be granted by someone who has the capacity to grant it; you cannot obtain one after the fact.

The route in that situation is guardianship of property, either through an application to the court to be appointed guardian, or through the statutory process involving the Office of the Public Guardian and Trustee following a capacity assessment. Both are legal processes with cost and delay attached. That is the whole argument for doing the paperwork years early, while everyone is well and the conversation is calm rather than urgent.

If you are having that conversation with a parent now, it belongs in the same discussion as everything else in helping your parents downsize: not a crisis meeting, a normal one, held early.

How does this change the listing itself?

Less than people expect, and in specific ways.

Under TRESA, in force since 1 December 2023, everyone in a transaction is either a client of a brokerage, with full representation and fiduciary duties, or a self-represented party, to whom a brokerage must not give advice or opinions. In a power of attorney sale the seller client is the owner, with the attorney signing on their behalf; in an estate sale the client is the estate through its trustee. That sounds technical, and it has a real consequence: my duties run to the owner or the estate, not to whichever family member is most involved in the file. Adult children sometimes find that uncomfortable. It is the correct answer.

Beyond that, the practical differences are documentation and pace. Signatures may need to be arranged around care schedules or a hospital. Nothing should be signed under time pressure. And I will want to see, in writing, that the lawyer is satisfied the seller can convey title before we go live — because the worst outcome in this category is not a slow sale. It is a firm sale that cannot close.
