The three core documents, why they matter, and how to get your affairs in order.
Who this is for & what you'll get: Any Ontario adult — whether you're 25 and renting or 65 with a paid-off home — who wants to understand the basics of estate planning without the jargon. You'll learn the three documents almost everyone needs, what happens if you skip them, and a simple checklist to start putting your plan together.

Why "estate planning" isn't just for the wealthy
The phrase estate planning sounds like something for people with summer homes and stock portfolios. It isn't. An "estate" is simply everything you own when you die — a bank account, a car, a phone full of photos, and a security deposit all count. Estate planning is just deciding, in advance and in writing, two things:
- Who handles your affairs and makes decisions for you if you can't (because of illness or injury, while you're alive); and
- Who gets what after you die.
If you don't decide, Ontario law and the courts decide for you — and the result is often slower, more expensive, and not what you would have chosen.
There are five things to understand. We'll take them one at a time.
1. The three core documents
Most adults need three documents working together. They cover two different situations — while you're alive but incapable, and after you die.
A Will
Your Will is the instruction sheet for after you die. It names the person who will carry out your wishes (your estate trustee, still commonly called an executor), says who inherits your property, and — if you have young children — names a guardian for them.
A Will only takes effect on death. It does nothing while you're alive.
A Power of Attorney for Property
A Power of Attorney for Property ("POA for Property") names someone to manage your money and property — pay bills, deal with the bank, handle the house — while you are alive if you become unable to do it yourself. In Ontario this is governed by the Substitute Decisions Act, 1992.
A continuing (or enduring) POA for Property is the kind that keeps working even after you lose mental capacity. That's almost always the point of having one, so make sure yours says it is continuing.
A Power of Attorney for Personal Care
A Power of Attorney for Personal Care ("POA for Personal Care") names someone to make decisions about your health care, housing, food, and personal safety if you can't make them yourself — for example, consenting to medical treatment or choosing a long-term care home.
Tip: People often confuse a POA for Personal Care with a "living will." In Ontario, written wishes about end-of-life care are usually expressed through your POA for Personal Care and conversations with the person you appoint — there isn't a separate court-recognized "living will" form.
2. What happens if you don't have them
Skipping these documents doesn't avoid the problem — it just hands the decision to a default process. Here's what that looks like.
No Will — you die "intestate"
If you die without a valid Will, you die intestate. Ontario's Succession Law Reform Act then dictates who inherits, in a fixed order, regardless of what you would have wanted. A spouse and children share the estate according to a statutory formula; if there's no spouse or children, it passes to other relatives in a set sequence.
Things that surprise people:
- A common-law partner does not automatically inherit on an intestacy in Ontario, no matter how long you were together. (They may have other claims, but the automatic intestacy share goes to a married spouse.)
- The spouse's first share is set by a "preferential share" figure in the statute. As of writing this amount is set by regulation and changes over time — verify the current figure with a lawyer or ServiceOntario before relying on it.
- The court must appoint someone to administer the estate, which is slower and may require posting a bond.
No POA for Property or Personal Care — guardianship
If you lose capacity without a POA, no one automatically has the right to step in — not even your spouse. Someone must apply to become your court-appointed guardian, or in the meantime the Office of the Public Guardian and Trustee (a provincial office) may become involved in your financial affairs. That process costs money, takes time, and means a court (or a government office) — not you — decides who is in charge.
⚠️ Watch out: A common myth is "I'm married, so my spouse can just handle everything." For health consent there's a legal hierarchy of substitute decision-makers, but for property — selling a house, accessing certain accounts — your spouse generally cannot act for you without a POA or a guardianship order.
3. Beneficiary designations: the plan that runs around your Will
Some of your biggest assets may pass outside your Will entirely, straight to whoever you named as beneficiary. These include:
- RRSPs and RRIFs
- TFSAs
- Life insurance policies
- Pension plans
You name a beneficiary directly with the institution. When you die, that asset typically goes to the named person regardless of what your Will says.
⚠️ The classic mistake: Someone names an ex-spouse as the beneficiary of their RRSP years ago, updates their Will after the divorce, and never updates the designation. The Will leaves everything to the new family — but the RRSP still goes to the ex. Review your designations whenever life changes.
A coordinated plan checks that your Will, your beneficiary designations, and how your accounts are owned all point in the same direction.
4. The supporting work: your list, your people, your storage
A Will is only as good as the information and people behind it. Three practical tasks make everything easier.
Make an asset & liability list
Your executor can't deal with an account they don't know exists. Create a simple inventory of:
- Assets: bank and investment accounts, real estate, vehicles, business interests, RRSP/TFSA/pensions, insurance, valuable personal items, and digital assets (online accounts, cryptocurrency, domain names, loyalty points).
- Liabilities: mortgage, loans, lines of credit, credit cards, taxes owing.
Keep it general enough that it stays current, and tell your executor where to find the detail.
Choose your executor and attorneys carefully
These are real jobs, not honours. The person should be:
- Trustworthy and organized — they'll handle money and paperwork.
- Willing — ask first; don't surprise them.
- Reasonably located and available — an executor overseas can struggle with in-person tasks.
- Likely to outlive you and stay capable — which is why you name alternates.
You can name the same person for more than one role, or split them up. Many people name a spouse first and an adult child or sibling as alternate.
Decide where to store the documents
A Will no one can find is nearly as bad as no Will. Store the original signed Will somewhere safe and accessible to your executor — a fireproof box at home, a lawyer's vault, or a safety deposit box (be aware a box can be hard to access right after death). Tell your executor where it is. Keep copies of your POAs accessible too, since they may be needed quickly in an emergency.
5. Review your plan — it's not "set and forget"
Life changes; your plan should keep up. Review your documents:
- Every 3–5 years as a default, and
- After any major life event: marriage, separation or divorce, a new child or grandchild, a death in the family, buying property, starting a business, a significant change in your finances, or moving provinces.
Note: In Ontario, marriage no longer automatically revokes a Will for marriages that take place on or after January 1, 2022 (a marriage before that date could still have revoked an existing Will) — but separation and divorce can affect gifts to a former spouse. The safe move is simply to review and update after any relationship change rather than rely on the default rules.

- Set a reminder to review every 3–5 years and after major life events
Mini-FAQ
Do I really need a lawyer, or can I use a kit? You can write your own Will, but small errors — improper witnessing, vague wording, missing the residue — can invalidate it or trigger an expensive court fight after you're gone, when you can't fix it. For most people the cost of professional drafting is small compared with the risk.
I'm young with few assets. Is this premature? The Will may be simple, but the Powers of Attorney matter at any age — accidents and illness don't wait. If you have any dependants or own anything, you have an estate.
Are my online accounts and crypto covered? Only if you plan for them. List your digital assets and make sure your executor can locate (legally) the information needed to deal with them. Never put passwords in your Will itself, which can become a public document through probate.
How often should I update everything? Every few years, and after any big life change — see Section 5.
