POWERS OF ATTORNEY IN ONTARIO: WHAT THEY REALLY DO
April 20, 2026
BY: IAN ANDREW LAW
You have probably heard the phrase “you should get a power of attorney” from a doctor, financial advisor, or insurance broker. It often comes up in passing, as if it were just another form to sign and forget. This article is meant to slow that down and give you a simple, high-level breakdown of what powers of attorney actually are, and why they matter.

KEY TAKEAWAYS:
Powers Of Attorney Are Powerful Legal Tools, Not Just Formalities.
Property and Personal Care POAs cover different parts of your life.
A POA Can Be Limited And Temporary Or Designed To Continue During Incapacity.
Capacity For Money Decisions Is Different From Capacity For Personal Care.
Your Attorney Must Act For You, Not For Themselves, And Cannot Make A Will For You.
WHAT A POWER OF ATTORNEY REALLY IS
A power of attorney is a legal document in which you give someone else authority to act for you in certain parts of your life. You are not giving up your rights while you are capable. You are choosing who can step in if you cannot act, or when it is simply more practical for someone else to sign or make the decision.
TYPES OF POWERS OF ATTORNEY FOR PROPERTY
A power of attorney for property deals with money, property, and legal or financial decisions.
Sometimes it is limited and temporary. For example, you might be out of the country and need someone to sign closing documents for a home sale or deal with a specific bank matter. Once that situation is over, the document is no longer needed.
Other times, it is meant to continue if you become mentally incapable of managing your own property. In that case, the document is designed to keep working even when you no longer understand your finances or the consequences of financial decisions. That is often what people mean when they talk about “planning ahead” with a power of attorney.
POWERS OF ATTORNEY FOR PERSONAL CARE
A power of attorney for personal care covers decisions about your body and your day-to-day life: health care, where you live, what help you receive, and similar choices.
Capacity for personal care is not the same as capacity to manage money. A person might be able to understand simple decisions about treatment and daily living, but not complex financial products or legal claims. The law treats these areas separately, and someone may need help in one area but not the other.
HOW CAPACITY AND INCAPACITY FIT IN
Under Ontario law, “capacity” is about understanding the information needed for a decision and appreciating what may happen if you make it or do nothing. That test is applied to the specific type of decision in front of you.
For property, the focus is on whether you understand your assets, debts, and the impact of financial decisions. For personal care, the focus is on whether you understand your condition, the options available to you, and what those choices could mean for your safety and well-being. A person may move in and out of capacity over time, and may be capable of some decisions but not others.
WHAT YOUR ATTORNEY CAN AND CANNOT DO
An attorney for property can usually pay bills, manage accounts, handle investments, and address legal or financial matters within the scope of the document. An attorney for personal care can usually speak with health professionals, help decide on treatment, and make choices about living arrangements and support.
There are important limits. An attorney does not become the “owner” of your property. They must act in your best interests and in accordance with the document and the law. They also cannot make a Will for you or change your existing Will. Some decisions may still require court involvement or be subject to other legal restrictions.
In situations where no power of attorney is in place, the alternative may be a court guardianship application. See our article on Guardianship in Ontario.
