Power of Attorney, Living Will, Last Will What's the Difference?
Ontario has several legal documents that protect you and your family, but confusing names make it hard to know what you actually need. This guide clears it up in plain language.

Four Documents, Four Jobs
Ontario residents are protected by a handful of legal documents, each covering a different part of life. The problem? They sound similar, they go by a dozen different names, and most people only think about them during a crisis. Here's what each one actually does.
The Naming Problem
If you've searched for information about these documents, you've probably seen a dizzying list of terms — health care proxy, advance directive, medical directive, living will, durable power of attorney, healthcare power of attorney, mandate — and wondered if they're all the same thing.
They're not. But the confusion is understandable. Many of these names come from American or other-province terminology that doesn't map directly to Ontario law. Ontario's legislation (the Substitute Decisions Act, 1992 and the Health Care Consent Act, 1996) uses very specific names that differ from what you'll see in everyday conversation or on American websites.
Why this matters
Using the wrong term — or thinking two documents are the same when they're not — can leave gaps in your protection. A "living will" is not a "last will." A "health care proxy" is not a "power of attorney for property." Getting these confused can mean your family still can't pay your bills, or your medical wishes go undocumented.
Available on RLF
Power of Attorney for Property
Continuing Power of Attorney for Property · SDA, 1992 s. 7
Appoints someone to manage your finances, real estate, banking, investments, and bills if you become unable to do so yourself.
Also Known As
Financial Power of AttorneyDurable Power of AttorneyContinuing POACPOAEnduring Power of AttorneyMandate (Quebec term)
What It Covers
Bank accounts, investments, real estate transactions, bill payments, tax filings, insurance
When It Kicks In
When you become mentally incapable (or immediately, if you choose)
Who You Appoint
An "Attorney for Property" — typically a spouse, adult child, or trusted person (18+)
Key Fact
"Continuing" means it continues after you become mentally incapacitated - this is important!
Power of Attorney for Personal Care · SDA, 1992 s. 46
Appoints one or more specific people to make healthcare, medical treatment, and personal care decisions on your behalf, and includes space to document your wishes.
Also Known As
Health Care ProxyHealthcare Power of AttorneyMedical Power of AttorneyPOPCPOAPCAdvance Directive (partial)Designation of Health Care Representative
What It Covers
Medical treatment, living arrangements, diet & hygiene, safety, end-of-life care
When It Kicks In
Only when you become mentally incapable of making personal care decisions
Who You Appoint
An "Attorney for Personal Care" — someone you trust with healthcare and personal decisions
Key Fact
This is Ontario's closest equivalent to what Americans call a "health care proxy." It can also include living will–style wishes.
POAPC vs. Living Will — the overlap
A Power of Attorney for Personal Care lets you document your wishes and it appoints a decision-maker for when you become incapacitated. A standalone Living Will lets you document your wishes, but it does not appoint a specific decision-maker.
No specific Ontario statute — records "prior capable wishes" per HCCA, 1996
A personal document that records your healthcare wishes, end-of-life preferences, and care instructions — without appointing a decision-maker.
Also Known As
Advance Care DirectiveAdvance DirectiveHealth Care DirectiveMedical DirectivePrior Capable WishesPersonal Directive (Alberta term)
What It Covers
End-of-life treatment, life support, comfort care, burial/cremation wishes
When It Applies
When you cannot communicate your wishes — used as evidence of your intentions
Who You Appoint
Nobody — this document records wishes only, it does not grant authority to anyone
Key Fact
Ontario has no statute specifically called a "Living Will" — but the HCCA requires decision-makers to follow your "prior capable wishes," which this documents
Governed by the Succession Law Reform Act, R.S.O. 1990
Dictates what happens to your property, assets, and dependants after you die. This is the document most people simply call a "will."
Also Known As
WillTestamentLast WillTestamentary Will
What It Covers
Asset distribution, guardianship of minor children, executor appointment, specific bequests
When It Applies
Only after your death — it has no effect while you're alive
Who You Appoint
An "Executor" (or "Estate Trustee") who carries out your instructions after death
Key Fact
Completely different from a Living Will — this deals with assets after death, not healthcare while alive
The #1 confusion
A Living Will and a Last Will & Testament are completely unrelated documents. A Living Will deals with your healthcare decisions while you're alive. A Last Will deals with your assets after you die. The only thing they share is the word "will."
Here's how the four documents stack up against each other:

Which Documents Do You Need?
The right documents depend on your situation. Here are the most common scenarios:
"We're a married couple with kids"
You need financial and healthcare coverage for both of you, plus guardianship instructions for your children.
→ Both POAs + Last Will (each spouse)
"I'm single, no dependants"
Living Will (document your decisions in advance) and POA for Property (if you have financial assets exceeding $50k).
→ Living Will + POA for Property
"I already have a POA for Health but want to update it"
You have two options. If you want to change who makes decisions for you, you need to generate a new POA for Personal Care. If you just want to update your wishes, a Living Will is appropriate.
→ New POAPC (to change who) OR
→ Living Will (to update wishes)
"I'm an aging parent"
The most common scenario for needing all documents. Health and cognitive decline make these especially urgent.
→ Both POAs + Last Will
"My spouse can handle everything, right?"
A common misconception. In Ontario, your spouse cannot automatically access your bank accounts, sell property, or make medical decisions without proper documents.
→ Both POAs (at minimum)
"I just want my end-of-life wishes on paper"
If you don't need to appoint a decision-maker but want your treatment preferences and care instructions documented.
→ Living Will
