A power of attorney is one of the most important legal documents a person can have, and one of the least understood. Most people associate the term with lawyers, but in Ontario a ‘power of attorney’ is not a document that gives your lawyer authority to act for you. It is a document that gives another person, often a family member or close friend, the legal authority to manage your affairs if you cannot do so yourself.
The situations that make a power of attorney necessary come suddenly and without warning. A stroke, a serious accident, a progressive illness, a surgery with complications, or simply the gradual onset of cognitive decline can all leave a person unable to manage their own finances or make their own healthcare decisions. Without a properly drafted power of attorney in place, family members who want to help often cannot do so legally. The formal process of obtaining authority through the courts is slow, expensive, and public in a way that most families do not want.
This guide explains how powers of attorney work in Ontario, the two types you need to know about, who can grant one, who can be appointed as attorney, what an attorney can and cannot do, the formal requirements for a valid document, and what happens when someone becomes incapacitated without one. For the companion document in your estate planning, see our guide on how to make a will in Ontario. A will governs what happens to your estate after you die; a power of attorney governs what happens while you are alive but unable to act for yourself.
What Is a Power of Attorney in Ontario
A power of attorney is a legal document in which a person (called the grantor or donor) gives another person (called the attorney) legal authority to make decisions or take actions on the grantor’s behalf. The attorney does not have to be a lawyer. The word ‘attorney’ in this context simply means a person who is authorized to act for another. The attorney can be a spouse, an adult child, a sibling, a close friend, or a professional.
Under Ontario’s Substitute Decisions Act, 1992, there are two distinct types of power of attorney, each governing a different domain of a person’s life. They serve different purposes, have different execution requirements, and are used in different circumstances. Most Ontarians doing comprehensive estate planning will want both. Understanding the difference between them is the foundation of understanding powers of attorney in Ontario.
The Two Types of Power of Attorney in Ontario
Continuing Power of Attorney for Property
A Continuing Power of Attorney for Property (CPOAP) authorizes your attorney to manage your financial and legal affairs. The word ‘continuing’ is critical: it means the power of attorney remains valid and in effect even if you become mentally incapable. A power of attorney for property that is not designated as ‘continuing’ automatically terminates if you lose mental capacity, which defeats much of its purpose.
The scope of authority granted under a Continuing POA for Property is broad. Your attorney can manage bank accounts, pay bills, file your tax returns, collect money owed to you, deal with government agencies on your behalf, buy and sell investments, and manage or sell real estate. The document can be drafted to limit this authority in various ways, or to grant it fully. The scope is determined by what the document says.
A Continuing POA for Property can be drafted to take effect immediately upon signing, which gives the attorney full authority from that point onward. Alternatively, it can be drafted as a ‘springing’ power of attorney, which takes effect only when a specific event occurs (usually a determination of incapacity). Most lawyers recommend the immediate form with appropriate safeguards, because springing provisions require assessments of incapacity that can be time-consuming and contested, often at exactly the moment when the authority is most urgently needed.
Power of Attorney for Personal Care
A Power of Attorney for Personal Care (POAPC) authorizes your attorney to make decisions about your health care, treatment, and personal care when you cannot make those decisions yourself. This includes decisions about medical treatment, surgery, medication, where you will live (including admission to a long-term care facility or a hospital), and decisions about your hygiene, nutrition, and safety.
Unlike the Continuing POA for Property, which can take effect immediately, a Power of Attorney for Personal Care only takes effect when you lack the capacity to make the personal care decision in question. If you are capable of making a healthcare decision yourself, your attorney has no authority to override you. The attorney’s role only arises when you cannot exercise your own judgment.
A Power of Attorney for Personal Care is particularly important for communicating healthcare wishes in advance. While an ‘advance care plan’ or instructions about end-of-life preferences can be included within the document, the POAPC also designates who has legal authority to make those decisions on your behalf, which gives the document a standing that informal instructions do not have.
Key Difference at a Glance
| Continuing POA for Property | POA for Personal Care | |
| Governs | Financial and legal affairs | Healthcare and personal care |
| Takes effect | Immediately on signing (or specified event) | Only when you lack capacity for that decision |
| Stays valid if incapacitated | Yes (the ‘continuing’ designation) | Automatically activates on incapacity only |
| Attorney can act while you are capable | Yes (with immediate POA) | No |
| Ends at death | Yes (estate governed by your will) | Yes |
Both documents are separate and both are recommended as part of a complete estate plan.
Who Can Grant a Power of Attorney in Ontario
To grant a power of attorney, you must have the mental capacity to do so. For a Continuing POA for Property, Ontario law requires that you understand the nature and effect of the document, the kind of property you have and its approximate value, that your attorney will be able to do anything you could do with your property (with some exceptions), that your attorney must account for their dealings with your property, that you may revoke the power of attorney at any time while you are capable, and that the power of attorney continues to be effective if you become incapable.
For a Power of Attorney for Personal Care, you must understand what the document means, that the attorney can make decisions on your behalf, and that you can revoke it at any time while capable. The test for capacity is generally lower than the test for making a will, but higher than simple orientation to time and place. People in early stages of cognitive decline may still have capacity to grant a power of attorney, while someone who fully understands their surroundings may lack the specific capacity to understand the legal effect of the document. This is a nuanced determination that a lawyer is positioned to assess.
If you delay making a power of attorney until after capacity becomes questionable, the document may be challenged by family members, healthcare providers, or the Office of the Public Guardian and Trustee. Making your powers of attorney while you are clearly capable, and doing so with legal assistance, removes that vulnerability.
Who Can Be Your Attorney
Choosing your attorney is one of the most important decisions in the power of attorney process. Your attorney will have significant legal authority over your affairs, and the relationship depends almost entirely on trust. The right choice varies for every person and family, but a few principles apply broadly.
Your attorney must be a person you trust completely with matters of the kind the POA covers. For a property attorney, that means someone who is financially responsible, organized, and capable of dealing with banks, government agencies, and potentially a complex financial picture. For a personal care attorney, that means someone who knows your values, your healthcare preferences, and who will advocate for your wishes even under pressure from medical professionals or other family members.
The attorney does not need to be a lawyer or a professional. Spouses and adult children are by far the most common choices. The attorney must be at least 18 years old for property matters, and at least 16 years old for personal care matters. Certain people cannot be your attorney for property, including persons under 18 and organizations (other than trust companies). The attorney should be someone who is likely to outlive you, to be geographically accessible, and to be willing to take on the responsibility.
Multiple Attorneys
You can appoint more than one attorney, either to act jointly (requiring both to agree on every decision) or jointly and severally (either can act independently). Joint authority provides a check on any one attorney acting unilaterally, which can be a safeguard in families with multiple children. Jointly and severally authority provides flexibility, so that one attorney can act even if the other is unavailable. Both arrangements have trade-offs, and the right choice depends on your family circumstances.
Successor Attorneys
You can designate a successor attorney, who takes over if your primary attorney is unwilling or unable to continue. This is good practice even when you are confident in your primary choice. Circumstances change. A spouse may predecease you, a child may move abroad, or a primary attorney may themselves become incapacitated. A well-drafted power of attorney anticipates these possibilities.
What Your Attorney Can and Cannot Do
The authority granted under a power of attorney is significant, but it is not unlimited. Understanding both the scope and the limits of your attorney’s authority is essential to making informed choices in drafting and in choosing your attorney.
Property Attorney: Powers and Limits
A property attorney can generally do anything with your property that you could do yourself, except make or change your will. This means managing bank accounts, paying your bills, dealing with your mortgage, buying and selling investments, managing a rental property, and dealing with the CRA on your behalf. The property attorney has a fiduciary duty to act in your best interests and to keep careful accounts of all transactions involving your property.
Your attorney cannot make or change your will, change beneficiary designations on life insurance or registered accounts, give away your property unless expressly authorized in the document (or unless you had an established pattern of making gifts), or transfer your property to themselves unless expressly authorized. There are also rules about conflicts of interest that prevent the attorney from benefiting personally from their management of your affairs.
Personal Care Attorney: Powers and Limits
A personal care attorney can make healthcare and personal care decisions when you lack the capacity to do so. The attorney must act in accordance with your known wishes expressed while you were capable. If your wishes are not known, the attorney must act in your best interests, taking into account your values, beliefs, and any instructions you may have given in the document itself or in an accompanying advance care plan.
A personal care attorney cannot override your decisions while you are capable. This is fundamental: the attorney’s authority only activates when your own capacity fails. The attorney also cannot authorize treatments that are not in your best interests, and they cannot consent on your behalf to something you explicitly refused while capable, except in narrow circumstances where emergency care is needed.
Safeguards Against Misuse
Ontario law includes several safeguards against misuse of powers of attorney. A property attorney must keep accounts and can be compelled to provide them on request. Anyone who suffers a loss because an attorney misused their authority can seek compensation through the courts. The Office of the Public Guardian and Trustee can investigate complaints about attorneys and can apply to the court to remove an attorney who is not acting in the grantor’s interest. Family members can apply to court to challenge an attorney’s conduct. These safeguards exist because elder financial abuse through misuse of powers of attorney is a real concern. The best defence is choosing a trustworthy attorney and, where appropriate, building accountability measures into the document itself.
How to Make a Valid Power of Attorney in Ontario
Ontario’s Substitute Decisions Act sets out specific formal requirements for a valid power of attorney. A document that does not meet these requirements is not a valid power of attorney and cannot be relied on.
Formal Requirements for a Continuing POA for Property
- Must be in writing.
- Must be signed by the grantor in the presence of two witnesses.
- Both witnesses must also sign in the presence of the grantor.
- The following people cannot be witnesses: the attorney or the attorney’s spouse or partner, the grantor’s spouse or partner, a child of the grantor or a person the grantor has treated as their child, anyone who receives a gift or benefit under the grantor’s will or intestacy, and anyone under 18.
- The attorney does not need to sign the document to accept the appointment, but cannot act until they do accept (usually implicitly, by first using the authority).
Formal Requirements for a POA for Personal Care
- Must be in writing.
- Must be signed by the grantor in the presence of two witnesses.
- Witnesses must sign in the presence of the grantor.
- The following people cannot be witnesses: the attorney or the attorney’s spouse or partner, the grantor’s spouse or partner, anyone under 16, any person whose job it is to provide personal care services to the grantor for compensation, and certain assessors involved in capacity assessments.
Why a Do-It-Yourself Kit Is Not Enough
Power of attorney kits are widely available online and at stationery stores. They provide a template document that can be filled in with names and dates. What they do not provide is the judgment required to match the document to your specific family circumstances, the advice needed to make informed choices about the scope of authority, the assessment of your capacity that gives the document its validity and reduces the risk of future challenge, the witnessing and execution assistance that ensures formal compliance, or the knowledge of how the document will interact with your other estate planning documents, including your will. These omissions matter. A poorly drafted power of attorney can be challenged, can fail at the moment it is most needed, or can create disputes within families that cost far more to resolve than the original legal fees would have. See our guide on how to make a will in Ontario for a similar discussion in the context of will kits.
What Happens Without a Power of Attorney
A common misconception is that family members automatically have the legal authority to manage an incapacitated person’s affairs. In Ontario, they generally do not. Without a valid power of attorney, the consequences of incapacity are handled in ways that are slower, more expensive, and more disruptive than a well-drafted document would have been.
Guardianship Through the Courts
When a person without a Continuing POA for Property becomes incapacitated, a family member or other interested person can apply to the Ontario Superior Court of Justice for an order appointing a guardian of property and, separately, a guardian of the person. These applications require significant documentation, legal expertise, a court hearing, and ongoing court reporting by the guardian. The process can take months and typically costs thousands of dollars. The court record is also public, which many families find unwelcome.
The Office of the Public Guardian and Trustee
In some circumstances, particularly where no family member steps in or where there is conflict about who should serve as guardian, the Office of the Public Guardian and Trustee (OPGT) will become the statutory guardian of property. The OPGT is a government office that manages the affairs of incapable persons, but it does so according to a government mandate rather than the personal wishes and family context that an appointed attorney would bring. Most people, if asked, would prefer to have a family member or trusted friend manage their affairs than a government office.
Healthcare Decisions Without a POA for Personal Care
Ontario’s Health Care Consent Act establishes a hierarchy of substitute decision-makers for healthcare decisions when a person lacks capacity and has no POA for personal care. The hierarchy goes: guardian of the person, then spouse or partner, then adult children, then parents, then siblings, then other relatives. While this provides a fallback, it does not give you control over who makes those decisions, and it can create conflict in families where the person at the top of the hierarchy is not the person the incapacitated individual would have chosen.
Revoking or Changing a Power of Attorney
You can revoke a power of attorney at any time while you have the mental capacity to do so. Revocation must be done in writing and signed in the presence of a witness who meets the same requirements as the witnesses to the original document. You should notify your attorney of the revocation, notify any financial institutions or other parties that were relying on the old document, and if possible retrieve and destroy the original copies.
If you want to change the scope of an existing power of attorney, amend the attorney’s authority, or appoint a different attorney, the cleanest approach is usually to revoke the existing document and execute a new one rather than attempting to amend the original. Amendments can create ambiguity about which version governs, particularly if the attorney is dealing with a third party who saw only the original.
Power of Attorney and Your Overall Estate Plan
A power of attorney and a will serve complementary purposes in a complete estate plan. Your will governs what happens to your property after your death: who inherits, who administers the estate, and what happens to your minor children. Your powers of attorney govern what happens while you are alive but incapable: who manages your finances and who makes your healthcare decisions. Both documents are necessary. A will without a power of attorney leaves a gap during incapacity; a power of attorney without a will leaves a gap after death.
For most people, a complete estate plan consists of three documents: a will, a Continuing Power of Attorney for Property, and a Power of Attorney for Personal Care. These three documents, drafted together with legal advice, provide comprehensive coverage for the full range of circumstances your family may face. They should be reviewed and updated after major life events such as marriage, divorce, the death of a named attorney, a significant change in your financial situation, or a move to a different province. See our guide on wills and estates for lawyers who can help with the full estate plan.
For newcomers to Ontario who have property or family members in another country, the estate plan may need to account for assets and legal relationships in more than one jurisdiction. An immigration lawyer and a wills and estates lawyer working together can ensure that the Canadian documents are structured in a way that coordinates appropriately with the grantor’s home country legal requirements.
Why a Wills and Estates Lawyer Who Speaks Your Language Matters
The decisions involved in making a power of attorney are deeply personal. Who do you trust to manage your finances if you are incapacitated? Who should make healthcare decisions for you if you cannot? What are your wishes about end-of-life care? These are not questions that most people can answer quickly in a second language during a formal legal consultation. They require reflection, family discussion, and the ability to communicate nuance clearly.
For many communities in the GTA, the power of attorney conversation is also a culturally significant one. In families where eldercare is traditionally handled within the family, the idea of formalizing that arrangement in a legal document may feel unfamiliar or even inappropriate. In communities where the first generation came to Canada with little and built significant assets over decades, the question of who controls those assets if the grantor becomes incapacitated can carry enormous emotional and relational weight. A lawyer who speaks your language and understands your community can navigate these conversations in a way that a lawyer working through interpretation cannot.

How to Find a Wills and Estates Lawyer in the GTA
Powers of attorney are most effectively drafted as part of a broader estate plan, alongside your will. A wills and estates lawyer can advise on both documents together, ensuring they are consistent, legally valid, and tailored to your specific family and financial circumstances. To find a lawyer, visit the Lawyers Who Speak directory, filter by Wills and Estates and your language, and narrow by location. For advice on choosing and engaging a lawyer, see our guides on questions to ask before hiring a lawyer, the first legal consultation, and how much a lawyer costs in Ontario. Always confirm the lawyer is currently licensed by checking our verification process or the Law Society of Ontario’s public register.
If cost is a concern, see our guide on Legal Aid Ontario and our guide on how to get legal advice in Ontario for free and reduced-cost options. Community legal clinics across the GTA can sometimes assist with simple estate planning documents for qualifying individuals.
Frequently Asked Questions
Do I need a lawyer to make a power of attorney in Ontario?
You are not legally required to use a lawyer to make a power of attorney in Ontario. However, given the legal and personal significance of the document, using a lawyer is strongly recommended. A lawyer can confirm you have the capacity to grant the power of attorney (reducing the risk of future challenges), advise on the scope of authority appropriate to your circumstances, draft a document that accurately reflects your intentions, ensure the formal execution requirements are met, and coordinate the power of attorney with your will as part of a comprehensive estate plan. A poorly drafted or improperly executed power of attorney may be invalid or contested at the moment your family needs it most. For an overview of legal fee structures, see our guide on how much a lawyer costs in Ontario.
What is the difference between a Continuing Power of Attorney for Property and a Power of Attorney for Personal Care?
A Continuing Power of Attorney for Property authorizes your attorney to manage your financial and legal affairs, including bank accounts, investments, real estate, and tax filings. It is ‘continuing’ because it remains valid even if you become mentally incapable. A Power of Attorney for Personal Care authorizes your attorney to make healthcare and personal care decisions on your behalf, but only when you lack the capacity to make those decisions yourself. Both documents are part of a complete estate plan, which also includes a will. The will governs what happens to your estate after death; both types of power of attorney govern what happens while you are alive but incapacitated. For more on wills, see our guide on how to make a will in Ontario.
What happens if I become incapacitated without a Power of Attorney in Ontario?
Without a Continuing Power of Attorney for Property, a family member who wants to manage your financial affairs must apply to the Ontario Superior Court of Justice for a guardianship order. This process is slow, expensive (often several thousand dollars in legal fees), and produces a public court record. In some cases, the Office of the Public Guardian and Trustee will become your statutory guardian instead of a family member. Without a Power of Attorney for Personal Care, healthcare decisions for you will be made by the person at the top of Ontario’s substitute decision-maker hierarchy under the Health Care Consent Act: spouse or partner, then adult children, then parents, and so on. This may or may not be the person you would have chosen, and it provides no mechanism for communicating your specific wishes about treatment.
Can I revoke a Power of Attorney after I have made it?
Yes. You can revoke a power of attorney at any time while you have the mental capacity to do so. The revocation must be in writing, signed in the presence of a witness who meets the same requirements as the witnesses to the original document. You should give notice of the revocation to your attorney and to any institutions (banks, investment firms, government agencies) that were relying on the old document. Retrieving and destroying original copies is also recommended to prevent ongoing reliance on the revoked document. If you want to appoint a different attorney or change the scope of the power, the cleanest approach is usually to revoke the old document entirely and execute a new one.
Can I appoint the same person as my attorney for both property and personal care?
Yes. There is no requirement to appoint different people for your Continuing Power of Attorney for Property and your Power of Attorney for Personal Care. Many people appoint the same trusted family member as attorney for both, which simplifies the decision-making process if they become incapacitated. However, some people deliberately choose different attorneys for different domains: one child may be well-suited to financial management and a different child may be better placed to make healthcare decisions. The right choice depends on your family’s specific circumstances. A wills and estates lawyer can help you think through the implications of your choices in the context of your full estate plan.
