How to write a will in Ontario: the formal and holograph will rules in the Succession Law Reform Act, choosing an executor, signing and witnessing, and storing and updating the will.
A will is a written document that sets out who inherits your property, possessions, and other personal items after you die. In Ontario, the rules for making a valid will come from the Succession Law Reform Act. This guide covers the process only — the steps to write, sign, witness, store, and update a will. It is not legal advice, and it does not tell you what to leave to whom. If your situation is complicated — a blended family, a business, property outside Ontario, a child with a disability, or any doubt about whether your wishes will hold up — talk to an Ontario wills lawyer before you sign anything. Ontario.ca says the same thing: if you have questions about your will, consult a lawyer.
Step 1: Decide what the will has to cover
Before you write anything, make a plain list:
- Property: your home and any other real estate, vehicles, bank accounts, investments, RRSPs and TFSAs, and any business interests.
- Personal items: furniture, jewellery, vehicles, collections, and anything with sentimental value that could cause an argument.
- People: who gets what, and who gets what is left over (the residue) after specific gifts are made. Name a backup for each important gift in case the first person dies before you.
- Children: if you have minor children, who should care for them, and who should manage any money left for them until they are old enough.
- Debts: the will should direct your estate trustee to pay your debts first; anything left after debts and gifts is the residue.
A will speaks as if it had been made immediately before your death, so it covers property you acquire after you sign it, not just what you own today. That is why the list matters more than the exact wording of each gift: the list is what you will work from when you write the will.
Step 2: Choose an estate trustee (executor) and a backup
Your estate trustee — often still called the executor — is the person who carries out the will: gathering your property, paying debts, and distributing what is left. Ontario.ca describes the estate trustee as your personal representative, the person authorized to administer your estate. Pick someone you trust to handle paperwork and money carefully, who is likely to outlive you, and who lives close enough to deal with Ontario institutions. Name a backup in case your first choice cannot or will not act.
Tell both people you have named them, and tell them where the signed original will be kept. A will nobody can find is no better than no will: Ontario.ca notes that a copy of a will may be in the person's home, in a safety deposit box, or with their lawyer, and that you can check with the estates division of the local Ontario court to find out if a will has been filed.
Step 3: Pick the form of will — formal or holograph
Ontario recognizes two routes, and the choice decides what the signing looks like.
A formal will is the standard route and the one a lawyer will normally prepare. The document can be typed or printed. Under section 4 of the Succession Law Reform Act, it is valid only if:
- it is signed at its end by you, or by someone else in your presence and at your direction;
- you make or acknowledge that signature in the presence of two or more witnesses present at the same time; and
- at least two of those witnesses sign the will in your presence.
No particular form of attestation is needed — the witnesses do not have to sign a special declaration, just subscribe the will.
A holograph will is a will written wholly in your own handwriting and signed by you. Under section 6 of the Succession Law Reform Act, it needs no witnesses and no other formality. "Wholly" is the catch: a typed document with a handwritten signature is not a holograph will, and a pre-printed will form filled in by hand is not one either. Use a holograph will only as a stopgap — for example, if you cannot reach a lawyer or two witnesses in time — and replace it with a formal will as soon as you can, because unclear handwriting or wording is harder for a court to interpret after you die.
One more limit: an electronic will is not valid in Ontario. The court's power to validate a badly executed document does not extend to electronic wills.
Step 4: Sign and witness it correctly
The signing is where most homemade wills fail, so follow the order exactly.
- Read the whole document first. Check every name, every gift, and the estate trustee appointment before anyone signs.
- Sign at the end. Put your signature at, after, following, under, or beside the end of the will, so it is clear on the face of the document that you meant the signature to give effect to the writing as your will. Nothing that gives property away can sit below your signature: a gift or direction written underneath the signature, or added after you signed, does not take effect.
- Date the will. Dating is not one of the statutory requirements for a formal will, but it matters if more than one will turns up — the later one normally replaces the earlier one. Write the date in full.
- Have both witnesses present at the same time. You sign or acknowledge your signature while both witnesses watch. Then both witnesses sign the will while you watch. They must both be present together, not one after the other.
- Choose witnesses who do not benefit. Do not use a beneficiary, or the spouse of a beneficiary, as a witness: any gift to that witness or their spouse is void as far as they are concerned, unless a court is satisfied there was no improper or undue influence. Your estate trustee can be a witness — being the executor does not by itself disqualify them — but a witness with no stake in the will is cleaner.
- Use ink and keep the original on paper. The will must be a physical, written document. Keep the signed original, not just a photocopy.
If you sign by video, the extra rule applies: at least one witness must be a lawyer or paralegal licensed under the Law Society Act, and the signing and witnessing must happen at the same time, with each person signing identical copies that together form the one will.
Step 5: Store the original where it can be found
Tell your estate trustee where the signed original is, and keep it somewhere they can reach without a court order after your death. Common choices are with your lawyer, in a fireproof box at home that your estate trustee can open, or in a safety deposit box — but check that your estate trustee can get into the box, since a bank may need proof of authority first. Keep a photocopy for yourself, clearly marked as a copy, and keep the original separate from the copy so nobody mistakes one for the other.
If you die without a will, your estate is distributed according to the Succession Law Reform Act rather than your wishes, and the court may have to appoint someone to administer it. Ontario.ca notes that a court may need to grant probate — confirming the estate trustee's authority, or authorizing a person to act as estate trustee — and that if there is no known next-of-kin in Ontario, the Office of the Public Guardian and Trustee may end up administering the estate.
Step 6: Update the will when life changes
Review your will after every major change: marriage, divorce, separation, the birth or adoption of a child, a death among your beneficiaries or your estate trustee, buying or selling a home, or a big change in what you own. Two rules from the Act matter here:
- Divorce and separation revoke parts of a will. Unless the will says otherwise, a divorce or a declaration that the marriage is void revokes gifts to your former spouse, their appointment as estate trustee, and any power of appointment given to them — the will is read as if your former spouse had died before you. The same applies if you were separated at death under the Act's definition, which includes living separate and apart for three years because the marriage broke down, a valid separation agreement, or a court order or arbitration award settling your affairs.
- Marriage no longer revokes a will. Since January 1, 2022, getting married does not cancel a will you made before the marriage. Do not assume an old will is gone because you married — check it.
To change a will, make a new will or a codicil executed with the same formalities. Do not cross out lines or write in the margins of a signed will: an alteration made after signing has no effect unless it is executed like a will, with your signature and the witnesses' signatures beside or near the change, or at the end of a note in the will that refers to the change. To cancel a will entirely, make a new will, sign a written declaration of revocation executed like a will, or destroy the will by burning, tearing, or otherwise destroying it with the intention of revoking it. A revoked will can only be brought back by a new will, a codicil showing that intention, or re-signing it with the required formalities.
If a will was not properly executed, the Superior Court of Justice can still order it valid if it is satisfied the document sets out the deceased person's testamentary intentions. That power applies only where the person died on or after January 1, 2022, and it is a court application by your family after your death — not something to rely on when a proper signing would have avoided the problem.
What this guide could not verify
The cost of having a lawyer draft a will in Ontario was not published on the Ontario.ca pages or the Succession Law Reform Act text, so this guide states no lawyer fee and no will-kit price. Probate court fees — the fees to apply for a certificate of appointment of estate trustee — were also not verified on the official pages, so no probate fee is stated here. Confirm both with the lawyer you consult or with the Ontario court office before relying on any figure. The Ontario.ca pages also did not publish a checklist of what an estate trustee must do after a death, so this guide does not list those steps.

Questions people ask
What makes a will valid in Ontario?
Under the Succession Law Reform Act, a will must be in writing. A formal will must be signed at its end by you (or by someone in your presence and at your direction), you must make or acknowledge that signature in the presence of two or more witnesses present at the same time, and at least two of those witnesses must sign the will in your presence. A holograph will is the exception: it must be wholly in your own handwriting and signed by you, with no witnesses and no other formality. A signature must be placed so it is clear you intended it to give effect to the writing as your will, and anything written below the signature does not take effect.
How old do I have to be to make a will in Ontario?
You must be 18 or older. A will made by someone under 18 is not valid unless, when making it, the person is or has been married, is contemplating marriage to a named person and the will says so (and the marriage then takes place), is a member of a regular force or on active service with the Canadian Forces, or is a sailor at sea or on a voyage. Members of the Canadian Forces on active service, members of other forces on active service, and sailors at sea may also make a will by a writing signed by them without any witnesses.
What is the difference between a formal will and a holograph will?
A formal will is the standard route: the document can be typed or printed, and it must be signed at its end in front of two witnesses who are present at the same time and who then sign it in your presence. A holograph will must be written wholly in your own handwriting from start to finish and signed by you — no witnesses are needed. A typed document with a handwritten signature is not a holograph will, so it needs the two witnesses. Holograph wills are the riskier route: unclear wording is harder to fix after you die, and a court may have to interpret it.
Can my witnesses inherit anything in my will?
Do not name a witness as a beneficiary. If a will is witnessed by a person to whom, or to whose spouse, the will gives property, that gift is void as far as it concerns the witness, the spouse, or anyone claiming under them — although the witness can still prove the will was properly signed. The exception is narrow: the gift stands if the Superior Court of Justice is satisfied that neither the witness nor the spouse exercised improper or undue influence over you. An estate trustee (executor) can act as a witness without that alone making them unable to prove the will.
Can I sign and witness a will over video in Ontario?
Yes, in limited circumstances. The Succession Law Reform Act allows the witnessing requirements to be met through audio-visual communication technology if at least one witness is a lawyer or paralegal licensed under the Law Society Act, the signing and witnessing happen at the same time, and any regulatory requirements are met. Each person can sign identical copies of the will in counterpart, and together those copies form the one will. If no licensed lawyer or paralegal is a witness, the signing must happen in person.
How do I change or cancel a will in Ontario?
Make a new will that follows the same signing and witnessing rules, or make a codicil — a written change that is itself executed like a will. A will can also be revoked by a signed writing that declares the intention to revoke and is executed like a will, or by burning, tearing, or otherwise destroying it with the intention of revoking it. Changes scribbled on a will after it is signed have no effect unless they are executed like a will, with your signature and the witnesses' signatures beside or near the change. Marriage no longer revokes a will, but divorce or a qualifying separation does revoke gifts to a former spouse and their appointment as estate trustee, unless the will says otherwise. A will that was revoked can only be revived by a new will, a codicil showing that intention, or re-execution with the required formalities.
