Selling Real Estate Under Power of Attorney in Ontario

When a homeowner can no longer manage their own affairs — because of illness, injury, or absence abroad — a trusted person may need to step in and sell the property on their behalf. In Ontario, that authority comes from a continuing power of attorney for property, and using one to close a real estate transaction is more complicated than most people expect.

Title insurance companies flag POA sales for heightened scrutiny. Mortgage lenders often have their own approval requirements. And if the document was drafted carelessly or executed improperly, the deal can collapse on closing day. Understanding what the law requires before you list the property will save everyone a great deal of stress.

What Is a Continuing Power of Attorney for Property in Ontario?

Ontario's Substitute Decisions Act governs who may make financial and property decisions for another person. A continuing power of attorney for property (CPOA) is a written legal document in which one person — the grantor — authorizes another person — the attorney — to manage the grantor's financial affairs, including buying and selling real estate.

The word "continuing" is important: it means the authority survives the grantor's subsequent mental incapacity. A non-continuing power of attorney terminates if the grantor loses capacity, which makes it nearly useless for the situations where a POA is most often needed.

Formal Requirements for a Valid POA

To be valid under Ontario law, a continuing power of attorney for property signed since 1995 must:

• Be in writing and signed by the grantor in the presence of two witnesses
• Be signed by each of those two witnesses as witness
• Exclude certain people from serving as witnesses (the attorney, the attorney's spouse, the grantor's spouse or partner, the grantor's child, anyone under 18, anyone with a guardian of property or personal care over them — SDA s. 10 (2))
• Be signed while the grantor has legal capacity to grant the power

There is no general requirement to register a CPOA, but to register a transfer signed by an attorney, the POA must generally be registered at the land registry office at or before that time.

Mental Capacity of the Grantor

One of the first questions a lawyer reviewing a POA sale will ask is: did the grantor have capacity when they signed the document? Capacity has a legal test: at signing, the person had to know, among other things, what kind of property they had and its approximate value, and what the attorney would be able to do with it.

If there is any doubt — for example, if the grantor was diagnosed with dementia before signing — the title insurer or the buyer's lender may require medical evidence, an affidavit from a physician or capacity assessor, or a court order. Attempting to rely on a POA signed while the grantor lacked capacity can expose the attorney to personal liability and may void the transaction entirely.

Can an Attorney Sell Property to Themselves or Family?

Generally, no. Ontario's Substitute Decisions Act imposes strict duties on attorneys for property. An attorney must act in the grantor's best interests and avoid conflicts of interest. Selling the grantor's property to themselves, their spouse, or a corporation they control can be a serious breach of fiduciary duty and is potentially void.

If an attorney genuinely believes a self-dealing transaction is in the grantor's interest, which would be rare, court approval may be required. Do not attempt this without independent legal advice.

What Title Companies and Lenders Scrutinize

When a transaction involves a POA, both the buyer's title insurer and the buyer's mortgage lender will review the document closely. Expect scrutiny of:

• Date of execution: Is the POA old enough that the grantor's circumstances may have changed significantly?
• Scope of authority: Does the language actually authorize the sale of real property, or is it limited to specific assets?
• Capacity concerns: Any evidence of capacity issues at the time of signing
• Revocation: Has the grantor revoked the POA since it was made? A revocation must be in writing and signed and witnessed the same way as the POA itself
• Standing restrictions: Some POAs are springing powers that only take effect on a triggering event (such as incapacity) — and the attorney must prove the trigger has occurred

Many lenders will also require a statutory declaration (sworn statement) from the attorney confirming the grantor was alive and had not revoked the POA as of closing. Your real estate lawyer will draft this for you.

What Happens If the Grantor Dies Before Closing?

A power of attorney terminates automatically on the grantor's death — even a continuing one. If the grantor dies between the time the Agreement of Purchase and Sale is signed and the closing date, the attorney's authority evaporates.

In that situation, the estate's executor (named in the will) or an estate administrator (appointed by the court) takes over authority to complete or unwind the transaction. This is not an automatic process. If you are acting under a POA and the grantor's health is precarious, flag this risk with your lawyer before signing any agreement.

Guardian of Property as an Alternative

If no valid POA exists and the grantor has already lost capacity, someone must be appointed guardian of property. Ontario has two routes: a court-appointed guardianship from the Ontario Superior Court of Justice, or — where the statutory criteria are met — a statutory guardianship arranged through the Office of the Public Guardian and Trustee following a capacity assessment. Either route is far more involved than a POA, requiring a formal application and a capacity assessment, but the result is similar: a named guardian gains authority to manage the incapable person's property, including selling real estate.

Guardianship takes time and money. If you suspect a loved one is losing capacity, encouraging them to execute a proper CPOA while they still can is far more practical.

Practical Checklist for POA Sellers

Before listing a property where a power of attorney will be used:

• Locate the original POA document and confirm it is a continuing power of attorney for property
• Confirm the document was properly witnessed and the grantor had capacity at signing
• Check whether the POA contains any restrictions on selling real property
• Confirm the grantor is still alive and has not revoked the POA
• Engage a real estate lawyer before signing any agreement — the buyer's lawyer and lender will ask questions you need to be ready to answer
• Be prepared to swear a statutory declaration on closing confirming capacity and non-revocation
• If the grantor's capacity is in doubt, obtain a capacity assessment and discuss with your lawyer whether a court order is needed
