Codicil to Will (Canada)

A Codicil to Will in Canada is a legally binding written instrument. It directs the distribution of the testator's estate to named beneficiaries upon death.

In Canada, Wills and codicils are governed exclusively by provincial and territorial legislation, as the federal Parliament has no jurisdiction over the testamentary laws governing real and personal property within a province. The key provincial statutes are Ontario's Succession Law Reform Act (R.S.O. 1990, c. S.26), British Columbia's Wills, Estates and Succession Act (S.B.C. 2009, c. 13), Alberta's Wills and Succession Act (S.A. 2010, c. W-12.2), Manitoba's The Wills Act (C.C.S.M. c. W150), Saskatchewan's The Wills Act, 1996 (S.S. 1996, c. W-14.1), and Quebec's Civil Code provisions on wills (arts. 703-775 C.C.Q.).

All of these statutes require that a codicil be executed with the same formalities as an original Will: the testator must sign the codicil at the end (or acknowledge a prior signature) in the simultaneous presence of two witnesses, each of whom must then sign in the testator's presence and in each other's presence. The witnesses must be adults who are not beneficiaries under the Will (or spouses of beneficiaries in provinces that include this restriction) — a witness who is also a beneficiary does not invalidate the codicil, but will typically lose their bequest under the gift to a witness rules in provincial legislation (e.g., Ontario SLRA s.12, BC WESA s.43).

A codicil is appropriate when the changes needed are specific and limited: for example, changing the executor or alternate executor, updating the address or name of a beneficiary, increasing or decreasing a specific cash bequest, changing the guardian appointed for minor children, adding a new beneficiary, or revoking a particular gift. It is generally not appropriate where the changes are extensive, where the interaction between the codicil and the original Will would create ambiguity, or where the original Will itself is poorly drafted and the codicil would compound the confusion.

The codicil must clearly identify the Will it is amending (by date of execution) and specifically state which provisions are being added, changed, or revoked, and in what manner. It should then expressly confirm that all other provisions of the original Will remain in full force and effect, and that the codicil is to be read together with the original Will as a single testamentary instrument.

A Codicil to Will is needed in any of the following situations:

**Change of Executor:** If the named executor has died, moved abroad, become incapacitated, or if the testator wishes to appoint a different person, a codicil can substitute the new executor without rewriting the entire Will.

**Change of Beneficiary:** If a named beneficiary has died, if the testator wishes to add a new beneficiary (such as a new grandchild or a charity), or if a specific bequest needs to be updated to reflect changed circumstances, a codicil provides an efficient solution.

**Updating Specific Bequests:** If the testator acquired new property (a vehicle, valuable artwork, or digital assets) that should be specifically bequeathed to a named person, a codicil can add this bequest without redrafting the entire Will.

**Guardian Changes:** If the guardian named for minor children in the original Will is no longer suitable or available, a codicil can name a new guardian.

**Correction of Errors:** If a minor error in the original Will — such as a misspelled name or incorrect address — should be corrected, a codicil can provide the correction.

**Changed Tax or Legal Environment:** If legislative changes affect the tax or legal consequences of specific provisions, a codicil may be used to update those provisions. However, extensive restructuring of an estate plan should be accomplished through a new Will.

A codicil should NOT be used when the changes are so numerous or significant that the interaction between the codicil and the original Will would be confusing or potentially ambiguous. In such cases, a completely new Will — which should expressly revoke all prior Wills and codicils — is the appropriate instrument.

Parties in Canada should prepare a Codicil to Will (Canada) proactively rather than waiting for a dispute to arise. Courts interpret agreements based on the written terms rather than oral representations. Under Canadian law, PIPEDA and provincial privacy legislation govern personal data processed under this agreement. The Competition Act (R.S.C. 1985, c. C-34), enforced by the Competition Bureau, protects consumer rights. Section 15 of the Canada Business Corporations Act governs corporate obligations. Provincial superior courts and the Federal Court of Canada have jurisdiction for civil matters. The Canada Revenue Agency (CRA) administers tax compliance obligations. Where the transaction involves regulated activities, prior approval from the relevant authority may be required before execution.

A valid Canadian Codicil must begin by clearly identifying the testator (the person making the codicil) by full legal name and current address, and by identifying the original Will being amended, including its exact date of execution. This identification is essential to establish the legal connection between the codicil and the Will it amends.

The amendment provisions must be stated with precision. For each change, the codicil should: (1) identify the specific clause or provision of the original Will being amended; (2) state clearly whether the provision is being revoked, substituted, or supplemented; and (3) set out the new provision in full. Vague amendments such as 'I change my executor' without specifying the original executor and the replacement will create ambiguity.

The confirmation clause is critical: the codicil must expressly state that all other provisions of the original Will that are not amended by the codicil remain in full force and effect, and that the original Will and the codicil are to be read together as a single testamentary instrument.

The execution requirements must be meticulously followed. The testator must sign the codicil at its end — not simply initial it or sign elsewhere — in the simultaneous presence of two adult witnesses who are not beneficiaries (or spouses of beneficiaries) under the Will. Both witnesses must then sign the codicil in the testator's presence and in each other's presence. The signatures should be accompanied by the full printed names and addresses of the witnesses, so they can be located to provide a witness affidavit (affidavit of execution) when the Will is probated. In Ontario, an affidavit of execution (under Rule 74.08 of the Rules of Civil Procedure) is typically required for probate. The codicil should be physically stored with the original Will and noted in any estate planning inventory held by the testator's solicitor.

Additional compliance elements for a Codicil to Will (Canada) used in Canada include: Under Canadian law, PIPEDA and provincial privacy legislation govern personal data processed under this agreement.
