Key Takeaways

  • A power of attorney for property and a power of attorney for personal care serve different purposes.
  • Ontario states that a person must generally be at least 18 to make a power of attorney for property and at least 16 to make one for personal care.
  • A continuing power of attorney for property can continue to operate during incapacity.
  • An attorney for property cannot make a will for the grantor.
  • Choosing the attorney is often more important than choosing a form.

What is a power of attorney?

A power of attorney is a legal document that authorizes another person to make certain decisions on your behalf. In Ontario, the two core estate-planning documents are the continuing power of attorney for property and the power of attorney for personal care.

The person giving the authority is often called the grantor. The person receiving the authority is the attorney. The attorney does not have to be a lawyer.

Power of attorney for property

A continuing power of attorney for property deals with financial and property matters. Depending on the wording, an attorney may be able to deal with bank accounts, bills, investments, real estate and other financial affairs.

The Substitute Decisions Act provides that a continuing power of attorney may authorize the attorney to do on the grantor’s behalf anything in respect of property that the grantor could do if capable, except make a will.

Ontario’s public guidance states that a person must generally be at least 18 years old and mentally capable to make a power of attorney for property.

Power of attorney for personal care

A power of attorney for personal care addresses decisions such as health care, housing, nutrition, clothing, hygiene and safety. It is designed for circumstances in which the grantor is incapable of making the relevant personal-care decision.

Ontario states that a person must generally be at least 16 years old and capable of giving the power of attorney for personal care.

Estate Planning Note

A will and powers of attorney do different jobs. A will operates after death. Powers of attorney are primarily concerned with decision-making while the grantor is alive.

When does a continuing power of attorney for property take effect?

This depends on the wording. Some documents are drafted to be usable immediately; others contain conditions or restrictions. People sometimes assume that a property POA can only be used after a formal incapacity finding, but that is not necessarily true.

Because immediate authority can be very broad, the choice of attorney and the drafting of restrictions deserve careful thought.

Who should you appoint?

The best attorney is not automatically the oldest child, nearest relative or person with the strongest financial background. The role requires judgment, reliability, record-keeping and an ability to act loyally in the grantor’s interests.

Consider whether the proposed attorney lives nearby, whether two attorneys can realistically cooperate, and whether a backup should be named.

Can you appoint more than one attorney?

Yes. A document can appoint multiple attorneys and specify whether they must act jointly or can act separately. Joint appointments can provide checks and balances, but they can also create delay if signatures or agreement are needed for routine decisions.

Do powers of attorney eliminate all substitute-decision issues?

No. Capacity is decision-specific, and Ontario law has separate regimes for health-care consent, guardianship and substitute decision-making. A well-drafted POA is an important planning tool, but it does not make every future dispute impossible.

When should documents be reviewed?

Review powers of attorney after major life events such as marriage, separation, the death or incapacity of an attorney, major relocation, family conflict, or a material change in assets. It is also sensible to revisit documents periodically to confirm that the appointed people remain appropriate.

Frequently Asked Questions

Do I need both types of power of attorney?

Many estate plans use both because financial decisions and personal-care decisions are legally distinct.

Can my attorney make a new will for me?

No. Ontario’s Substitute Decisions Act expressly excludes making a will from the authority of an attorney for property.

Does my attorney have to be a lawyer?

No. Ontario’s guidance expressly states that the attorney does not have to be a lawyer.

Can I revoke a power of attorney?

Often yes, provided the legal capacity requirements for revocation are met and the revocation is properly documented.
