- Key issue
- Whether gifts made through joint bank accounts, gift letters, and beneficiary designations can be set aside on grounds of undue influence or resulting trust when no dependency or dominance is proven.
- Outcome
- The Court of Appeal dismissed all grounds of appeal, confirming that the gifts were freely made, the presumption of resulting trust was rebutted, and corroboration requirements under the Evidence Act were satisfied.
- Why it matters
- If you are a beneficiary or family member disputing how assets were transferred before a loved one's death, this decision clarifies the high bar required to undo gifts made through joint accounts and signed gift letters.
Legal principle
The rule from this case
In Ontario, a presumption of undue influence only arises where there is actual potential for domination in the relationship between the person giving and the person receiving a gift. A court will not presume undue influence simply because two people were close or because one person was generous. The gift-giver must have been in a position of dependency or vulnerability to the recipient. Separately, when assets are transferred into a joint account or designated to a beneficiary, Ontario law presumes a resulting trust — meaning the law assumes the transfer was not intended as a gift unless proven otherwise. However, that presumption can be displaced on a balance of probabilities by clear evidence of donative intent, such as signed gift letters, the structure of joint accounts, and consistent beneficiary designations. Donative intent must exist at the time of the transfer, not after the fact.
Important limits
What this does not mean
This decision does not mean that undue influence claims in estates are impossible to prove. It confirms that the presumption requires real evidence of a power imbalance or dependency — not just a close or affectionate relationship. If genuine domination or vulnerability existed, a court can still find undue influence. The case also does not mean that depositing money into a joint account automatically completes a gift in every situation. The court found delivery was established on the specific facts here, including the absence of any change in the donor's capacity before the transfer was complete. Each case turns on its own evidence, and the presence or absence of written documentation like gift letters will be critical to the outcome.
Can a family member challenge an estate gift for undue influence in Ontario?
Yes — but the bar is high. Ontario courts require evidence of actual potential for domination in the relationship, not just closeness or generosity. In Buffa v. Giacomelli, 2026 ONCA 566 (CanLII), the Court of Appeal confirmed that a presumption of undue influence does not arise simply because someone received a substantial gift from a family member. The court found no dependency or dominance on the facts, and the gifts were shown to have been given freely and deliberately.
If you are questioning whether a transfer of assets before death was truly voluntary, the starting point is always the nature of the relationship — not the size of the gift.
What is the presumption of resulting trust and how does it apply to estate transfers?
The presumption of resulting trust means Ontario law does not automatically treat a transfer of assets as a gift. When one person transfers property to another — especially into a joint account — the law presumes the recipient holds it on behalf of the original owner’s estate unless there is clear evidence of an intention to give. This presumption exists to protect estates from informal transfers that were never truly meant as gifts.
In this case, the court applied the framework from Pecore v. Pecore, which allows courts to look at the quality of the relationship and surrounding circumstances to assess what the transferor actually intended. Gift letters, the structure of joint accounts, and beneficiary designations all pointed clearly toward donative intent. Taken together, they displaced the presumption of resulting trust on a balance of probabilities.
Does a gift have to be completed before the donor loses capacity?
Yes — donative intent must exist at the time of the transfer, and delivery must occur while the donor still has capacity. This is a firm rule in Ontario gift law. In this case, the court found that depositing condominium sale proceeds into a pre-existing joint account constituted valid delivery of the gift. Crucially, there was no finding that the donor’s capacity changed before that delivery was completed.
This means the timing of both the intent and the physical transfer matters enormously. If capacity deteriorated before the transfer was complete, the gift could be invalid — which is exactly why this factual finding was so important to the outcome.
What corroboration is required under Ontario’s Evidence Act for gift claims?
Section 13 of Ontario’s Evidence Act requires that a person’s testimony about a transaction with a deceased individual be corroborated by other evidence. In estate disputes, this often comes up when a beneficiary claims a gift was made but the only direct evidence is their own word.
The court clarified that corroboration applies to the factual contention being advanced — here, the intention to make a gift — not to each individual piece of evidence in isolation. The gift letters, beneficiary designations, and joint account documentation together provided meaningful corroboration that went beyond the recipient’s own testimony. This is a practical reminder that written documentation created at the time of a transfer is far more valuable than oral evidence alone.
How does a court decide whether a gift was freely given?
Courts look at the whole picture: the donor’s state of mind, the nature of the relationship, whether independent advice was obtained, and whether the documentation is consistent over time. A single gift letter signed close to death may raise questions; a pattern of consistent designations and written instructions over time is much harder to challenge.
Deference also plays a role. Appellate courts in Ontario follow the standard set in Housen v. Nikolaisen, which means findings of fact made by the original application judge are not easily overturned. If the trial-level judge found the gifts were freely and deliberately made, an appeal court will only intervene if there was a clear legal error — not simply because a family member disagrees with the outcome.
Practical takeaways for estate beneficiaries and family members
- Document gifts in writing at the time they are made. Gift letters signed by the donor, beneficiary designations, and joint account agreements are the most reliable evidence of donative intent.
- Understand the difference between closeness and dominance. A close or loving relationship does not automatically support an undue influence claim. Courts require evidence of actual power imbalance or dependency.
- Act quickly if you suspect a problem. Capacity and the timing of transfers are central to gift disputes. Evidence about the donor’s state of mind at the moment of transfer is often difficult to reconstruct after the fact.
- Get independent legal advice before challenging a transfer. The presumption of resulting trust can be rebutted by solid documentary evidence. Before launching an estate challenge, have a lawyer assess whether the corroboration threshold is realistically met.
- Appellate courts rarely reverse factual findings. If an application judge has already ruled on the facts, the window for appeal on those points is narrow. Early legal advice matters.

FAQ
Frequently asked questions
You need evidence of actual dependency or dominance in the relationship — not just closeness. Courts look for situations where the gift-giver was vulnerable to the recipient's influence, and a pattern of control or pressure is usually required to succeed.
It depends on the donor's intention at the time of the deposit. If there is clear evidence — such as gift letters or consistent beneficiary designations — that the donor intended the money as a gift, the estate's claim will likely fail. Without that evidence, the presumption of resulting trust may apply.
A gift letter is strong evidence but works best alongside other documentation like beneficiary designations and joint account records. Courts look at the full picture, and a single letter close to death may face more scrutiny than a consistent pattern of written instructions over time.
