Writing a will in Canada is simpler than most people assume — but the rules vary by province, and small mistakes can void the entire document. This guide explains what makes a will legally valid across Canadian jurisdictions, when you need a lawyer, and what an honest will actually costs.
A valid Canadian will has three core requirements regardless of province: the testator (the person making the will) must be at least 18 years old and of sound mind, the will must be in writing, and it must be signed in the presence of qualifying witnesses (or, in some provinces, written entirely in the testator's own handwriting).
Each province has its own statute. Ontario follows the Succession Law Reform Act, R.S.O. 1990, c. S.26. British Columbia follows the Wills, Estates and Succession Act (WESA), S.B.C. 2009, c. 13. Quebec is governed by the Civil Code of Québec, which treats wills very differently from common law provinces. Alberta follows the Wills and Succession Act, S.A. 2010, c. W-12.2.
Despite the different statutes, the underlying logic is consistent: the law wants clear evidence that the document reflects the testator's true and final intentions, executed without coercion, by a person who understood what they were doing.
The biggest divide in Canadian wills law runs between the common law provinces and Quebec. In Ontario, BC, Alberta, and the other common law provinces, a typed will is signed by the testator in front of two witnesses, who also sign. The will is privately held and goes to probate after death.
Quebec recognizes three forms of will: the notarial will (en forme notariée), the holograph will, and the will made in the presence of witnesses. The notarial will is signed before a Quebec notary and a witness, registered in the central register of wills, and — critically — does not require probate. This is a meaningful procedural difference that affects estate administration cost and timing.
Prairie provinces (Saskatchewan, Manitoba, Alberta) have their own wills acts that broadly mirror Ontario's framework but with statute-specific details. Atlantic provinces follow similar common law structures with provincial variations.
A holograph will is one written entirely in the testator's own handwriting and signed by them, without witnesses. Most Canadian common law provinces — Ontario, Alberta, Saskatchewan, Manitoba, New Brunswick, Newfoundland and Labrador, and the territories — recognize holograph wills as valid.
British Columbia, Prince Edward Island, and Nova Scotia do not recognize holograph wills as a category, although BC's WESA includes a curative provision (section 58) that allows a court to validate non-compliant documents in limited circumstances.
Holograph wills are useful in emergencies — a soldier deploying, a person near death — but they are a frequent source of estates litigation. Ambiguous wording, missing assets, missing executor appointments, and unclear residue clauses regularly send holograph wills to court.
For non-holograph wills, qualifying witnesses are essential. The general rule across Canadian common law provinces:
If a beneficiary or their spouse signs as witness, the will itself is usually still valid, but the gift to that beneficiary is generally voided. This is one of the most common ways homemade wills go wrong.
Your executor (called a liquidator in Quebec, or an estate trustee in Ontario probate filings) is the person responsible for administering your estate after death. They locate the will, apply for probate where required, gather and value assets, pay debts and taxes, and distribute what remains to your beneficiaries.
Executor duties take 12–24 months on a typical estate. The role is unpaid in family contexts unless the will provides for compensation, though provincial statutes allow for executor's compensation (commonly around 5% of the estate, subject to court review).
Choose someone organized, financially literate, geographically close, and younger than you. Naming a backup executor is essential — if your primary executor predeceases you or is unable to act, the court will appoint someone, often not who you would have chosen.
These are the errors most often raised in Canadian estates litigation:
Each of these is preventable with a properly prepared and properly executed will.
Most Canadians making a first will do not need a lawyer. A typical estate — a home, savings, registered accounts, a spouse and children, no business interests — is well-served by a properly prepared online will combined with proper execution.
You should consult a lawyer if you own a private corporation, have children from multiple relationships with potential competing claims, hold significant property in another country, are considering disinheriting a dependant, have a complex disability provision (like a Henson Trust) needed for a beneficiary, or expect your will to be challenged.
