Selling a Home Under Power of Attorney
Selling a Home Under
Power of Attorney
in Ontario
Selling a property under Power of Attorney is one of the more commonly misunderstood real estate transactions in Ontario. Families navigating it are often managing a parent's declining health or cognitive capacity at the same time — which makes the legal complexity even harder to absorb. This guide covers what the law actually says, plainly.
This post is for informational purposes only and does not constitute legal advice. The information here has been cross-referenced against Ontario legislation, Ontario government publications and Ontario legal practitioners. Every situation is unique and you will need a qualified lawyer involved throughout this process.
What Is a Power of Attorney in Ontario?
In Ontario, a Power of Attorney is a legal document that gives one person — the attorney — the authority to act on behalf of another person — the grantor (sometimes called the donor). The attorney does not need to be a lawyer. The term refers to the role, not the profession.
Ontario's POA framework is governed by the Substitute Decisions Act, 1992, which came into force on April 3, 1995. The Act created two types of powers of attorney that families dealing with property matters need to understand:
For the purpose of selling a home, you need a Continuing Power of Attorney for Property. A Personal Care POA alone gives you no legal authority to deal with real estate.
Capacity — Why Timing Is Everything
This is the most critical point in this guide: a Power of Attorney must be granted while the grantor still has legal capacity. Under the Substitute Decisions Act, a person is capable of giving a Continuing POA for Property if they know what property they have and its approximate value, understand their obligations to dependants, know what they are authorizing the attorney to do and understand that they can revoke the POA as long as they remain capable.
Once a person loses mental capacity, they can no longer grant a POA. Families who wait too long often find themselves in a position where their parent can no longer manage their own affairs — but also can no longer legally authorize someone to act on their behalf. At that point, the only path forward is applying to the court for a guardianship order through the Public Guardian and Trustee, which is significantly more time-consuming and expensive than having a POA in place from the start.
“The best time to put a Power of Attorney in place is long before you need it. Once capacity is in question, the window to do it properly may already be closed — and the alternative is a court process.”
If no Continuing POA for Property is in place when a person loses capacity, neither family members nor anyone else can manage that person's property without court authority. The Office of the Public Guardian and Trustee may become involved as a temporary guardian. A family member wishing to take over must apply to court for guardianship of property — a process that takes considerably longer than a POA that was put in place in advance. Planning ahead is the only way to avoid this outcome.
The Attorney's Legal Duties — What Ontario Law Requires
Being named as someone's attorney for property comes with significant legal obligations under the Substitute Decisions Act. The Act requires attorneys to exercise their powers with honesty, integrity and good faith and for the incapable person's benefit.
POA vs Estate Sale — The Critical Difference
The single most important distinction between a POA sale and an estate sale is this: whether the grantor is still alive. A Power of Attorney operates only during the grantor's lifetime. An estate sale occurs after the grantor has passed away.
A Power of Attorney becomes void immediately upon the grantor's death. This is confirmed by Ontario government publications, CLEO Ontario, multiple Ontario estate lawyers and the Ontario Real Estate Source (a lawyer Q&A specific to real estate closings). Any action taken under a POA after the grantor's death — including signing documents, accepting an offer or completing a sale — has no legal authority. If a grantor passes away during an active listing or between an accepted offer and closing, the transaction must stop immediately and proceed through the estate instead, which may require the Certificate of Appointment of Estate Trustee (probate) — a process that can take many months.
When POA and Estate Sales Intersect
In practice, these two situations overlap more often than families expect. The most common scenario: a family member holds a Continuing POA for Property for an elderly parent. The parent requires long-term care, their home needs to be sold to fund that care, and the attorney lists and sells the property. This is a straightforward POA sale — proceeds go to the parent, authority comes from the POA document.
Where it becomes more complex: the listing is active or an offer has been accepted, and the parent passes away during that process. At the exact moment of death, the POA ceases to have legal effect. The attorney no longer has authority to complete the transaction. As confirmed by Ontario estate lawyers, the transaction must then proceed through the estate — which means the Estate Trustee must have authority to act, and if probate is required, the closing may need to be delayed by many months.
When handling a POA sale where the grantor is elderly or in declining health, experienced real estate agents and lawyers plan for the possibility of the grantor passing before closing. This includes having the estate lawyer involved early, confirming who the Estate Trustee is and whether a will is in place, and — where the timeline is a genuine concern — working to move the transaction forward as quickly as possible. A real estate agent who understands POA transactions will flag this risk proactively and structure the process accordingly.
The Real Estate Process — What's Different
A POA sale follows the same general real estate process as any other sale. But there are specific practical differences that both the real estate agent and the real estate lawyer need to be aware of:
Where to Start
If you are acting as an attorney for a family member and need to sell their home, the starting point is the same as for any complex real estate transaction: engage a lawyer experienced in this area and a real estate agent who has handled POA transactions before. Both need to be involved early.

If you are managing a POA situation and may eventually face an estate sale as well, reading the Estate Sales Guide alongside this post is worthwhile — the two situations share many of the same practical considerations, and planning for one often means planning for both.
