Probate touches a house in Ontario more often than people expect, and what it actually means depends entirely on how that house is owned. If you’ve inherited a house, or you’re the executor named in someone’s will, the two questions that matter most are what probate costs and whether the house can be sold before it’s finished. The short version: probate is a tax on the estate’s value, worked out through Ontario’s Estate Administration Tax, and a house can usually be listed and even sold conditionally before probate is granted, but the sale typically can’t close until it’s granted. This guide walks through both, plus the standard ways a homeowner can structure their own estate in advance to avoid or reduce probate on their house, alongside everything else covered in our complete Toronto real estate guide.
Does every house in Ontario go through probate?
No. Whether a house needs probate depends on how it’s held, not on its value or its location. A house owned in joint tenancy passes automatically to the surviving owner the moment the other owner dies, by right of survivorship, and it never becomes part of the deceased owner’s estate at all. Our guide to joint tenancy versus tenants in common in Ontario covers how that ownership structure works, and our guide to survivorship applications in Ontario covers the actual paperwork a surviving owner files to update the title afterward. A house held inside certain trust structures can bypass probate the same way, since the trust, not the person who died, already legally owns it.
A solely owned house, or a share held as tenants in common, is a different situation. That share forms part of the deceased’s estate, and an estate needs a named estate trustee with proven legal authority before anyone will deal with it. Land registries, buyers’ lawyers, and financial institutions all ask for that proof before they’ll act, and in Ontario, the proof is a Certificate of Appointment of Estate Trustee. Probate is simply the court process that produces that certificate. If a house is solely owned, or held as tenants in common, plan on probate being part of settling that estate.
What probate actually costs on a house in Ontario
Probate cost in Ontario runs through the Estate Administration Tax, a tax on the whole estate’s value, not a fee charged to a buyer or paid personally by the estate trustee out of their own pocket. Ontario charges nothing on the first $50,000 of an estate’s value, then $15 for every $1,000 above that, an effective rate of 1.5%, calculated on the application for a Certificate of Appointment of Estate Trustee. Ontario’s own page on calculating the tax sets out the full formula, confirmed current as of September 2026.
Because a house is usually an estate’s largest single asset, it usually drives most of the tax owed. Take a straightforward example: an estate made up mostly of a $900,000 house plus a modest bank account, totalling $950,000. The first $50,000 is tax-free, and the remaining $900,000 is taxed at 1.5%, for $13,500 in Estate Administration Tax owed before the estate can be distributed. The one deduction available specifically for real property: any mortgage or other encumbrance actually registered against Ontario real estate in the estate reduces the taxable value dollar for dollar, so that same estate with a $300,000 mortgage still registered against the house owes tax on $600,000 of taxable value instead, for $9,000.
The tax itself is paid up front, as an estimate, at the time the probate application goes in. It isn’t the last step. Ontario requires the estate trustee to file an Estate Information Return, confirming the estate’s actual asset values, within 180 days of the certificate being issued, and that return has to be submitted electronically through the Ministry of Finance’s online portal. Missing that deadline is a provincial offence under the Estate Administration Tax Act, and an estate that never files it can be audited with no time limit at all. For a house, this matters because the return needs a real, defensible value for the property as of the date of death, not a rough guess.
Can a house be sold or listed before probate is granted?
Usually, yes to listing, and yes to accepting an offer, but usually no to closing. An estate trustee can secure a house, insure it, instruct a real estate agent, and put it on the market before a Certificate of Appointment of Estate Trustee has actually issued. What typically can’t happen is the closing itself, the point where title legally transfers, because the buyer’s own lawyer and the land registry both need proof that whoever signs the transfer actually has legal authority to do it on the estate’s behalf. Without a certificate in hand, that proof doesn’t exist yet, and most buyers’ lawyers won’t proceed to registration without it.
In practice, this means an accepted offer on an estate sale is often written with a condition tied to the certificate being issued by a set date, so the deal can move to a firm agreement once probate actually comes through rather than stalling indefinitely. Treadstone Law’s own guidance on this exact question describes the same practical sequence: list and negotiate early, close once the certificate is in hand. A small number of narrow exceptions exist, tied to very small estates or specific title histories, but they’re uncommon enough that most executors should plan around the general rule rather than count on qualifying for one.
The standard ways to avoid or reduce probate on a house
Joint tenancy is the technique that applies most directly to a house. Two or more owners hold the property together with a right of survivorship built in, so when one dies, their share passes to the survivor outside probate entirely, using the mechanism covered in the two guides linked above. A house held inside a properly structured trust can bypass probate the same way, since legal ownership never sat with the person who died in the first place.
Multiple wills, splitting an estate into a primary will for assets that need probate and a secondary will for assets that don’t, is a real, court-confirmed technique in Ontario, upheld by the courts in the Granovsky Estate case. It’s used most often for privately held business interests, like shares in a family corporation, rather than for a personal residence. A house usually still needs to pass through the estate one way or another unless it’s held jointly or inside a trust, so multiple wills aren’t typically the main lever for a family home the way joint tenancy or a trust is. A lawyer can confirm whether the technique has any real application to a specific estate’s real property.
Beneficiary designations work well for other kinds of assets. RRSPs, RRIFs, TFSAs, and life insurance policies can all name a beneficiary directly and pass to that person outside the estate entirely, but this doesn’t apply to a house. Real property doesn’t carry a beneficiary designation the way a registered account does, so this particular technique reduces the rest of an estate’s exposure to probate without touching the house itself.
Adding a family member’s name to a house’s title is sometimes suggested as a shortcut, and it deserves a direct warning rather than a soft one. Our guide to transferring property title to a family member in Ontario covers exactly why this isn’t the simple, cost-free move it sounds like: the CRA treats it as a gift that triggers a deemed disposition at fair market value, whether or not any money actually changes hands, and the added owner’s own creditors and any relationship breakdown become the house’s problem too. Read that guide fully before treating this as a real probate-avoidance strategy rather than a decision with its own genuine costs.
What an executor or homeowner should actually do next
An executor or estate trustee dealing with a real house and a real estate needs an estate lawyer for that specific file, not a guide like this one. How much Estate Administration Tax is actually owed, whether probate can be reduced or avoided for a particular asset, and how quickly a certificate can realistically be obtained all depend on details specific to that estate: its assets, its beneficiaries, and whether anyone contests the will.
A homeowner thinking ahead about their own estate should have that same conversation before acting on any technique named above, since adding a joint owner, setting up a trust, or restructuring a will each carry their own real costs and consequences that a lawyer needs to weigh against that homeowner’s actual situation. If you’ve inherited a house and you’re ready to sell it once a certificate is in hand, our team can help with that next step directly. Get in touch with our team when you’re ready.
Frequently asked questions
Does every house in Ontario have to go through probate?
No, it depends entirely on how the house is owned. A house held in joint tenancy passes automatically to the surviving owner outside probate, and a house inside certain trust structures can bypass it the same way, since legal ownership already sits somewhere other than the deceased’s own estate. A solely owned house, or a share held as tenants in common, generally does have to go through probate, because the estate trustee needs a Certificate of Appointment of Estate Trustee before a land registry, a buyer’s lawyer, or a financial institution will treat them as having legal authority over it.
How much does probate cost on a house in Ontario?
Probate cost in Ontario is calculated through the Estate Administration Tax, a percentage of the whole estate’s value rather than a flat fee tied to the house alone. Ontario charges nothing on the first $50,000 of an estate and 1.5%, or $15 per $1,000, on everything above that. In the worked example above, a $950,000 estate built mostly around a $900,000 house comes to $13,500 in tax, since a house is usually an estate’s largest single asset and typically drives most of that number. The one deduction available specifically for real property is any mortgage or encumbrance still registered against that Ontario property, which reduces the taxable value directly.
Can a house be sold before probate is granted in Ontario?
Usually, a house can be listed and an offer accepted before probate is granted, but the sale typically can’t close until the estate trustee actually has a Certificate of Appointment of Estate Trustee in hand. Land registries and a buyer’s own lawyer need that certificate as proof that whoever signs the transfer has legal authority to do it on the estate’s behalf, and without it, they generally won’t proceed to registration. In practice, offers on an estate sale are commonly written with a condition tied to the certificate being issued by a set date, so the deal can move to closing once probate actually comes through. A handful of narrow exceptions exist, but most executors should plan around the general rule.
What happens to a house held in joint tenancy when an owner dies?
It passes automatically to the surviving owner by right of survivorship, and it never becomes part of the deceased owner’s estate, so it doesn’t go through probate and doesn’t factor into the Estate Administration Tax calculation at all. The survivor still has to update the title to reflect the change, which is a straightforward survivorship application, not a probate proceeding, covered in this site’s own guide to survivorship applications in Ontario. This is the clearest, most commonly used way a house avoids probate entirely in Ontario, though it only works where the house was genuinely held in joint tenancy before the death, not tenants in common.
Does adding a family member’s name to a house’s title avoid probate?
It can, but it isn’t the simple, cost-free shortcut it’s sometimes made out to be, and this site’s own guide to transferring property title to a family member in Ontario covers why in detail. Adding a co-owner creates a real gift in the eyes of the CRA, which can trigger a deemed disposition and a taxable capital gain on the added share’s fair market value, whether or not any money actually changes hands. It also exposes the house to that new co-owner’s own creditors and to any dispute that arises if their marriage or relationship breaks down. It’s a real technique, but treat it as a decision with genuine costs, not a free workaround.
Who should someone dealing with probate on a specific house actually talk to?
An estate lawyer, for the specific estate in question, not a general guide like this one. Whether probate can be reduced or avoided for a particular asset, how much Estate Administration Tax is actually owed, and how quickly a Certificate of Appointment of Estate Trustee can realistically be obtained all depend on details specific to that estate: its assets, its beneficiaries, and whether anyone disputes the will. A homeowner thinking ahead about their own future estate should have that same conversation before acting on joint tenancy, a trust, or a change to their will, since each carries real costs and consequences specific to that homeowner’s own situation, best discussed directly with a lawyer rather than decided from a guide like this one.
