Making a Valid Will in Ontario

Signing, witnesses, handwritten wills, and what makes a will fail

This is legal information only. For advice on your own circumstances, speak to a lawyer.

A will that is religiously sound but legally invalid distributes nothing. These are the Ontario requirements that decide whether the document works.

Ontario requirements

ItemOntario
Governing statuteSuccession Law Reform Act
CourtSuperior Court of Justice
Handwritten (holograph) willsValid
Probate costEstate Administration Tax: nil on the first $50,000, then about $15 per $1,000 of value above that (roughly 1.5%). A Small Estate Certificate is available for estates of $150,000 or less.
Spouse’s share on intestacy$350,000 for deaths on or after 1 March 2021 ($200,000 before that date).
Will registryNo central, searchable government registry of wills. The Superior Court registrar’s office is a statutory depository where a living person may deposit a will for safekeeping (Estates Act, s. 2), but it is a per-registry deposit facility, not a province-wide index that can be searched on death — which is the gap a private registry fills.
Claims against the estateDependant support claims under Part V of the Succession Law Reform Act. Ontario does not have a BC-style wills variation regime for independent adult children.

The failures that recur

Drafting note

A well-drafted Islamic will usually states the faraid shares explicitly, names a fallback distribution if a share fails, and appoints both an executor and a guardian. That is lawyer work, not template work.

Common questions

Can my spouse witness my will?

They should not. A gift to a witness or the witness's spouse can be void, even where the will itself remains valid.

Is a will I wrote by hand valid?

It depends on the province — several accept holograph wills, and at least one does not. Check the table above before relying on a handwritten document.

Do I need a new will if I get married or divorced?

Very likely. Marriage and divorce can revoke a will or the gifts in it, and the rules differ by province and by the date of the will.
