Keeping the New Housing Rebate After Adding a Co-Signer

The situation

Andriy worked as a call-centre representative and his younger brother Bohdan worked as a landscaper. Between them their combined income was modest, and after months of saving they had put together a deposit on a newly built townhome in Niagara Falls. The purchase price sat within reach of what a lender would advance against their two incomes, but only barely, and the mortgage broker was blunt about it: on their own, the brothers would not qualify for enough financing to close.

Their father, Raymond, offered to co-sign. He had a stable income and an unencumbered home of his own, and the lender was satisfied with his financial picture. But the lender's underwriting also came with a condition the brothers had not expected: Raymond would need to be added to the title of the new property, not just the mortgage. Some lenders will accept a guarantor who signs the loan documents without appearing on title, but this one required all parties responsible for the debt to also hold a registered ownership interest in the property securing it. Without that concession, the deal would not close at all.

The brothers agreed, signed the purchase agreement with all three names on it, and did not think much more about it until their real estate lawyer flagged a separate problem buried in the paperwork: the builder's HST new housing rebate.

The problem

When a builder sells a newly constructed home, the purchase price typically includes HST. Buyers who intend to use the home as their primary place of residence are generally entitled to a rebate of a portion of that tax under the Excise Tax Act. In most new-build deals, the builder credits the rebate directly against the purchase price at closing, on the understanding that the buyer will assign their right to claim it to the builder. If the rebate is later denied, the Canada Revenue Agency can claw the money back — usually from the purchasers, since they are the ones who signed the rebate assignment.

The rebate has a condition that trips up exactly this kind of family arrangement: at least one of the individuals registered on title must intend to use the home as their own primary residence, and the rebate can be reduced or denied where a person who holds title has no such intention and instead holds a genuine ownership stake purely as an investment. A parent added to title only to satisfy a lender is not, in substance, buying an investment property — but on paper, three names appear on the deed, and only two of them planned to live there. The builder's closing package, prepared before Raymond's involvement was finalized, listed all three purchasers on the rebate application without distinguishing between them.

The amount at stake was real money for a household on Andriy and Bohdan's income: the HST new housing rebate credited at closing came to just under $12,000. If the CRA treated Raymond as a co-owner with a genuine beneficial interest in the property, the agency could reassess the rebate on the basis that not all title holders qualified, and demand repayment of a portion of it — an unwelcome bill arriving well after the family assumed the matter was settled.

The distinction that matters to the CRA is between legal title and beneficial ownership. A person can be named on a deed — legal title — without actually owning any share of the property's value, its equity, or its obligations, if that arrangement is properly documented as a bare trust: the person holds title in name only, on behalf of the true owners, and has no beneficial interest of their own. Lenders often ask for a co-signer to appear on title precisely because it is faster and cheaper than structuring a formal guarantee, without giving any thought to what that does to the buyers' tax position.

What we did

1. Confirmed the lender's actual requirement. We reviewed the mortgage commitment with the brothers and their broker to establish precisely why Raymond needed to be on title, rather than simply signing as a guarantor. The commitment required a registered ownership interest but did not require Raymond to have any share of the equity, rental income, or resale proceeds — it only needed his name to appear as a titled owner the lender could look to if the mortgage went into default.
2. Prepared a bare trust and co-signer agreement. Before closing, we drafted a written declaration of trust confirming that Raymond held his interest in the property as bare trustee only, with no beneficial ownership, no entitlement to occupy the home, no claim to any increase in value, and no obligation beyond the mortgage guarantee itself. Andriy and Bohdan were confirmed as the sole beneficial owners in equal shares. The agreement also set out what would happen if the brothers later wanted Raymond removed from title once their income supported the mortgage on its own.
3. Corrected the rebate documentation with the builder's lawyer. We contacted the builder's closing lawyer directly to explain the trust arrangement and to make sure the rebate assignment reflected it accurately, rather than simply listing three co-owners with no distinction between them. The rebate application was amended to record that Andriy and Bohdan, as the beneficial owners, intended to occupy the property as their primary residence, and that Raymond's interest was held in trust for them only.
4. Preserved supporting evidence for the file. We kept a full paper trail — the trust declaration, the lender's commitment letter showing the reason Raymond was added to title, and correspondence confirming his lack of beneficial interest — in case the CRA later reviewed the rebate. A rebate that looks correct on its face can still be questioned years later, and having the underlying documentation ready at closing, rather than reconstructed afterward, is what actually protects a family in that position.
5. Advised on the eventual title change. Once the brothers' mortgage could be refinanced on their own credit, removing Raymond from title would be a straightforward transfer rather than a sale, since he never held a beneficial interest to begin with. We outlined that process in advance so the family would not face land transfer tax on a transfer that was, in substance, just tidying up a lender's paperwork.

The outcome

The deal closed on schedule, with the full HST new housing rebate credited against the purchase price as originally planned. Because the rebate assignment now correctly identified Andriy and Bohdan as the beneficial owners intending to live in the home, and Raymond as a bare trustee with no ownership stake, the family's position matched the requirements for the rebate rather than sitting in a grey area waiting to be caught.

Roughly eighteen months later, the CRA opened a routine verification review of the builder's rebate applications for that development, and the brothers' file was among those checked. Because the trust declaration and supporting correspondence were already on record from closing, the review closed without any adjustment or repayment demand. The full rebate stood, and the family avoided what could have been a repayment obligation of several thousand dollars arriving with little warning years after they had already spent the money renovating the basement.

Andriy and Bohdan refinanced the mortgage in their own names about two years after closing, once their combined income had grown enough to qualify without a co-signer. Removing Raymond from title at that point took a single transfer document rather than a resale, and because he had never held a beneficial interest, no land transfer tax applied to the change.
