Quick Answer
The short answer
When someone dies in Ontario, their will may be read as though a separated spouse had already died, even though that spouse is still living. Gifts to that spouse are cancelled, and so is their appointment as executor. The rule sits in section 17(3) of the Succession Law Reform Act, and section 43.1 removes the same spouse’s entitlement where there is no will. Separation must be established in one of four ways: three years living separate and apart, a valid separation agreement, a court order, or a family arbitration award. Sections 17(3) and 43.1 apply only to a will and to Ontario's intestacy rules, and do not change a beneficiary designation, jointly owned property, or a power of attorney.
What Changed, and Why It Catches People Out
For decades, a separated spouse stayed in line to inherit their late spouse's property under Ontario's estate rules, regardless of how long ago the couple had separated. A couple could live apart for 15 years, never divorce, and the surviving spouse typically remained the default heir and the named executor.
That changed on January 1, 2022. Amendments to the Succession Law Reform Act now treat a separated spouse much like how Ontario law has long treated a divorced one.
The difficulty is that separation has no certificate. A divorce has a date and a document behind it. Separation in Ontario can be gradual, informal, and undocumented. Therefore, the legislation sets out four specific circumstances in which a spouse counts as separated, each with its own timing condition. Most of the confusion starts there.
Marriage works differently
Marriage is a separate question with a separate answer. Marriage no longer revokes an existing will in Ontario, but that change is not retroactive. This means a marriage before January 1, 2022 generally did revoke a will made earlier. Our guide to estate planning mistakes Ontario families make covers that rule in full.

Quick Start: Find Your Situation
Find the situation closest to yours and read that section first.
You have lived apart for three years or more
The three-year route may apply. Read the sections on wills and intestacy, then check the timing condition in the section on dates.
You have signed a separation agreement
A route may already be established. Start with the four routes section.
A court order or arbitration award settled your affairs
A route may apply without waiting three years. Start with the four routes section.
You are separated, but nothing is formal yet
None of the four routes may be established. Read the sections on what separation does not change and on the claim that may survive.
How Ontario Treats a Separated Spouse Under a Will
The person who makes a will is the testator. The person appointed to carry it out is the executor, known in Ontario as the estate trustee. Section 17 has long applied this after a divorce, and since 2022, it applies on separation as well.
Only the parts of the will that involve the separated spouse are affected. The rest of the document typically stands. If the will names no alternate beneficiary and no alternate estate trustee, that gap can create difficulty for the family left behind.
This happens automatically, without anyone signing anything. Changing a will deliberately is different, and is set out in our guide to how to change your will in Ontario.
What Happens if There Is No Will
Intestacy means dying without a valid will. When that happens, the Succession Law Reform Act decides who inherits, and a married spouse normally comes first.
Section 43.1 is a separate rule from section 17(3), and it does a separate job. Section 17(3) reads a will; section 43.1 applies where there is none. Our guide to what happens if you die without a will sets out who inherits instead.
The Date That Causes the Most Confusion
Both dates appear in published Ontario material, often in the same article. The reason is a transition provision. The amendments apply only where the event that establishes separation happened on or after January 1, 2022. On the three-year route, the spouses must also have begun living separate and apart on or after that day.
Three years from January 1, 2022 is January 1, 2025. That is where the second date comes from. Nothing came into force in 2025.
The courts read it the same way. In McDowell v. McDowell, 2024 ONSC 2301, the Ontario Superior Court of Justice held that spouses who separated in 2020 fall outside the amendments.

Four Ways Ontario Law Treats Spouses as Separated
These are alternatives, not a checklist. A couple who signed a separation agreement last year does not also need to wait three years, and a couple who has lived apart for three years does not need an agreement.
Each route carries the same timing condition described above, so the date an event happened often matters as much as the event itself. An agreement signed in 2019 and a court order made in 2023 sit on opposite sides of that line.

What Separation Does Not Change
A beneficiary designation is the form, typically completed with a bank, insurer, or pension administrator, that names who receives that account on death. In Ontario, a valid designation generally governs the plan and passes outside the will, so a form naming a separated spouse can stay in force for years.
Joint tenancy with right of survivorship is co-ownership in which the surviving owner automatically takes the whole. Separation does not change that on its own.
A power of attorney continues until it is revoked. Our guide to power of attorney for property explains what the role covers. These rules are Ontario’s alone; other provinces set different thresholds.
The Claim a Separated Spouse May Still Bring
One statute closes the inheritance door. A second leaves a different door open.
Net family property is the growth in each spouse’s net worth during the marriage. Section 6(21) of the Family Law Act treats the intestacy entitlement as having a value of $0 where section 43.1 has removed it, which leaves the election intact. It is subject to a filing period that a court may extend on motion. Our page on equalization of net family property explains the calculation.

How to Review an Estate Plan After Separation
A review is a finite exercise. Most of it is gathering documents you already have and asking a few institutions a simple question in writing. The point is to find out what your documents currently say, rather than what you remember them saying.

Working through those six steps typically shows whether the estate plan still matches the family, or whether one or two documents need attention. Most people find one gap rather than several. Our wills and estates services cover wills, powers of attorney, and estate administration for families across Toronto, Scarborough, and the rest of the GTA.
Common Mistakes Separated Spouses Make
- ▪Assuming separation updated the will. It may revoke gifts to a spouse, but writes nothing new.
- ▪Assuming nothing changed without a divorce. Since 2022, that is no longer how the Act applies.
- ▪Treating three years as the only route. An agreement, court order, or arbitration award may each establish separation sooner.
- ▪Leaving beneficiary forms alone. These are the assets most often still pointing at a separated spouse.
- ▪Naming no alternate estate trustee. Where the named person is treated as having died first, someone often has to apply to the court. Our guide to how probate works in Ontario explains that appointment.
- ▪Waiting to see what happens. Where documents and expectations disagree, estate disputes and will challenges often arise.
Questions Ontario Readers Ask
I’m separated but not divorced. Can my spouse still inherit from me?
Is my ex still my executor if we separated?
How long do we have to be separated before it affects my will?
My separated spouse is still listed on my RRSP. Does my will override that?
Does separation cancel a power of attorney in Ontario?
We own the house together. Does separation change who gets it?
Can my separated spouse still make a claim against my estate?
Where to start
Separation may quietly rewrite a will and the intestacy rules, and it may leave beneficiary forms, joint ownership and powers of attorney exactly as they were. Those two facts together are what catch families out.
Checking the date on your will and requesting your beneficiary designations costs nothing and often answers most of the question. Nihang Law helps families across Toronto, Scarborough and the wider GTA with wills, powers of attorney and estate administration.
