An Estate Faces a Builder's Rebate Clawback Years Later

The situation

The letter arrived at the estate's mailing address six weeks after Erzsebet's funeral, addressed to her estate and copied to the builder that had constructed her home two years earlier. The builder was demanding repayment of the new housing rebate it had credited at closing, roughly 41,000 dollars, plus its own share of an HST assessment the Canada Revenue Agency had raised against the builder directly, a further sum that pushed the total exposure connected to the file into the 600,000 dollar range once the builder's broader self-supply reassessment across several units was factored in.

Erzsebet, a successful investment advisor, had bought a newly built home in Campbellford as what she told her family would be her retirement house, moving in within a year of closing. At closing, rather than paying the HST on the purchase price and later applying for the new housing rebate herself, she had assigned the rebate to the builder, who credited it against the purchase price so Erzsebet paid less upfront. That assignment is common; builders often prefer to handle the rebate directly so buyers do not need to file separately. It also meant the builder, not Erzsebet, was on the hook if the CRA later decided the rebate had never actually been available.

Melinda, Erzsebet's daughter and the executor of her estate, had known almost nothing about the purchase details until the builder's letter arrived. She had assumed, reasonably, that a completed home purchase from years earlier was a closed matter. Instead, she was now the estate representative facing a claim from the builder, who argued that because Erzsebet had not used the home as her primary residence for a long enough period before an eventual sale, the self-supply and rebate conditions had not been met, and the builder wanted the estate to indemnify it for the CRA's reassessment.

Katalin, the principal of the construction company that had built the home, had a very different account of the file's history than what Erzsebet had told her own family, and reconciling those two accounts, using records the estate itself held, would end up shaping almost everything that followed.

The self-supply rules that sat behind the demand exist to prevent a builder from avoiding HST by moving into a property it built rather than selling it, or by treating a rental unit differently from a sale. When a builder is deemed to have both sold and repurchased a completed home to itself, it must account for HST on the fair market value, and the new housing rebate credited at closing depends on the buyer genuinely intending to use the property as a primary residence. If that intention was never real, or the property's actual use changed quickly, the rebate can unravel, and the CRA can look to either the builder or the original recipient to make up the difference.

The risk we had to size

Before Melinda could respond to the builder's demand, we needed to size the actual risk to the estate, and that meant separating three questions that the builder's letter had run together. First, was the builder's own reassessment from the CRA correct at all, or was the builder facing exposure for reasons that had nothing to do with Erzsebet's particular unit, such as how it had reported other properties in the same development. Second, if the rebate on Erzsebet's unit specifically had been improperly claimed, whose responsibility was that under the assignment documents she had signed at closing. Third, even if the estate bore some responsibility, what portion of the builder's much larger total claim, which spanned several units, could fairly be attributed to Erzsebet's file rather than to the builder's broader problems.

The assignment documents mattered enormously here. When Erzsebet signed the rebate over to the builder at closing, the paperwork included a warranty that she intended to use the property as her primary residence. If the CRA's position was that this warranty was false when made, the builder could argue the estate should indemnify it, since the estate stood in Erzsebet's place. But if the CRA's real complaint was about how the builder itself had accounted for HST across multiple units in the development, unrelated to whether Erzsebet's own residency intention was genuine, then the estate's exposure was far smaller than the builder's letter implied.

This is where Erzsebet's own records became central, and where the picture got harder for the estate rather than easier. Melinda found, going through her mother's files as executor, that Erzsebet had moved into the home within the expected window and lived there for over a year, which supported a genuine primary-residence intention. But she also found a folder of listings and correspondence showing Erzsebet had actively marketed the property to short-term renters for several months during a period when she was travelling, arrangements that were never reported to the builder or reflected in the closing paperwork. Those records did not prove the rebate had been wrongly claimed at the outset, but they complicated any argument that the property's use had been purely residential throughout, and they meant the estate's own documents, not just the builder's assessment, would shape how much exposure remained. Sizing the risk honestly meant accounting for what those records actually showed rather than what the family had assumed about how Erzsebet had used the house.

What we did

1. Reviewed the closing documents and the rebate assignment line by line. We confirmed exactly what warranty Erzsebet had given the builder about her intended use of the property, and on what date, because the precise wording determined whether the estate's exposure turned on her stated intent at closing or on the property's later actual use, which are legally different questions with very different consequences for the estate.
2. Requested the builder's own CRA correspondence covering the broader development. Rather than accepting the builder's characterization of the reassessment, we asked for the underlying notice and the builder's response to it, which showed the CRA's concerns spanned several units and several different issues, only one of which touched Erzsebet's property, letting us separate the estate's genuine exposure from the builder's unrelated problems.
3. Disclosed the short-term rental records to the builder proactively. Once Melinda's review of her mother's files turned up the listings and correspondence, we chose to disclose them to the builder's counsel before they were discovered independently, on the view that credibility with the other side, and eventually with the CRA if the matter escalated, mattered more than hoping the records stayed buried.
4. Built a timeline showing the actual period of primary residence. We assembled utility records, mail forwarding dates, and the rental listings together to show precisely how long Erzsebet had genuinely lived in the home before renting it out temporarily, which let us argue for a partial preservation of the rebate rather than a full clawback, since the primary-residence condition had been met for a real, documented stretch of time.
5. Negotiated a cost allocation rather than a full indemnity. We pushed back on the builder's demand that the estate cover its entire proportional share of the multi-unit reassessment, arguing instead for an allocation tied specifically to the rental period the records showed, which limited the estate's contribution to the portion of the builder's claim actually connected to Erzsebet's own conduct.
6. Advised Melinda on the estate's own disclosure obligations. Because the discovery of the rental records changed what the estate could honestly represent to the builder and, if it came to that, to the CRA directly, we walked Melinda through what she was and was not required to volunteer as executor, so she could make an informed decision rather than guessing at her obligations under pressure.
7. Settled the estate's contribution and closed the file before further interest accrued. With the allocation agreed, we finalized a payment from the estate directly to the builder rather than leaving the matter open for the CRA to pursue independently, which stopped interest from continuing to build on an amount that had already been under dispute for the better part of a year.

The outcome

The estate ended up paying the builder roughly 210,000 dollars, an amount tied specifically to the months Erzsebet had rented the property out rather than to the builder's full multi-unit reassessment, which had originally implied a much larger share for her file. That figure was calculated against the timeline we built from her own records, not negotiated down from an arbitrary starting point, and both sides accepted it as a reasonable allocation once the underlying facts were laid out.

This was not a case where the estate avoided the consequences of what had actually happened. Erzsebet had genuinely rented the home out for a period that undercut the primary-residence basis for part of the rebate, and no amount of advocacy was going to erase that fact once her own records surfaced. The estate lost ground it could not have preserved through argument alone, and the family had to accept that the retirement house Erzsebet described to them was not managed quite the way she had told them at the time.

What limited the damage was acting on the records honestly rather than around them. Disclosing the rental listings before the builder found them independently avoided a much harsher negotiating position, and separating Erzsebet's genuine exposure from the builder's broader problems with other units in the development kept the estate from absorbing costs that were never really hers to bear. The estate closed within a year of the builder's original demand, without the matter escalating into a direct CRA assessment against the estate itself, which had been a real possibility earlier in the file.

Melinda now keeps a simple rule for administering the rest of the estate: treat every closing document and warranty her mother signed as something to verify against the underlying facts before assuming it was accurate, rather than taking family history at face value when a formal claim is on the table.
