If you’re buying a new home from a builder in Ontario, there’s a good chance your purchase agreement includes a clause where you assign your GST/HST New Housing Rebate to the builder rather than claiming it yourself after closing. It’s one of the most common — and most misunderstood — clauses in a new-build Agreement of Purchase and Sale (APS).
Understood correctly, it’s a convenience. Misunderstood, it can leave a buyer confused about what they actually paid, or exposed if their eligibility turns out to be different than assumed.
The Two Ways a Rebate Can Work
When a new home purchase qualifies for a GST/HST New Housing Rebate, there are generally two ways it gets to the buyer:
- The buyer pays the full price (including HST) and applies for the rebate afterward, receiving it directly from the government once the claim is processed.
- The buyer assigns their rebate entitlement to the builder as part of closing, and the builder reduces the amount collected at closing by the expected rebate amount — so the buyer never has to file a separate claim.
Most standard-form builder agreements in Ontario are structured around the second option, because it’s simpler for both sides: the buyer sees a closing figure that already reflects the rebate, and the builder handles the paperwork with the government directly.
Why Builders Prefer the Assignment Model
From the builder’s perspective, assignment avoids a common source of buyer complaints — a buyer who is quoted a headline price, closes, and then has to separately navigate a government rebate application to get money back weeks or months later. Bundling the rebate into the closing figure keeps the transaction simpler and the advertised price closer to what the buyer actually pays out of pocket.
What Buyers Should Confirm Before Signing the Assignment Clause
- Eligibility. The rebate generally depends on the home being used as a primary residence by the buyer or a qualifying relation. If you’re buying as an investment property for arm’s-length tenants, your eligibility picture is different, and an assignment clause built around owner-occupancy assumptions may not fit your situation.
- What happens if eligibility changes. Many builder agreements include a clause requiring the buyer to reimburse the builder for the rebate amount if it later turns out the buyer didn’t qualify — for example, because the home wasn’t used as a primary residence within the required period. Read this clause closely; it can create a real post-closing liability.
- Which rebate program is being assigned. Because there are currently multiple, overlapping rebate programs that can apply to a new home purchase depending on when the agreement was signed and when construction completes, confirm with your lawyer exactly which program the builder’s clause is assigning, rather than assuming it’s a single simple figure.
- How the price was presented. Some builders advertise a price already net of the expected rebate; others show the gross price and the rebate as a separate credit at closing. Either is common, but you should know which one you’re looking at.
A Simple Way to Think About It
| Without assignment | With assignment |
|---|---|
| Buyer pays full price including HST at closing | Buyer pays a reduced amount reflecting the expected rebate |
| Buyer files a rebate application with the government afterward | Builder claims the rebate directly; no separate buyer application |
| Buyer receives rebate funds later, if eligible | Buyer never sees separate rebate funds — it’s already netted out |
| Buyer bears the risk of a rejected or delayed claim | Buyer may owe the builder back if eligibility isn’t met |
Why This Article Doesn’t State a Rebate Amount
The dollar figures and eligibility formulas for new-home HST/GST rebates are unusually unsettled as of mid-2026 — there’s a long-standing base program plus newer and proposed enhancements that apply differently depending on your closing timeline, and sources on the current numbers have been inconsistent even within the same government body. Rather than repeat a figure that might already be out of date by the time you read this, confirm the current rebate amount and eligibility rules directly with your lawyer or the builder’s sales office before you rely on any number.
Frequently asked questions
Do I have a choice about whether to assign the rebate?
Often the builder’s standard-form agreement is presented as a package, but it’s still worth asking your lawyer to review the clause before you sign — particularly if your intended use of the home doesn’t clearly fit the owner-occupancy assumption the rebate is generally built around.
What if I’m not sure I’ll qualify for the rebate at all?
Flag this with your lawyer before closing, not after. If eligibility is uncertain, you want to understand what the agreement says happens to the price if the rebate assignment doesn’t go through as planned.
Can I still get the rebate if I decide to rent the home out to a tenant instead of living in it?
Owner-occupancy rebates and rental-property rebates are different programs with different rules. If your plans change from personal use to rental, that’s a material fact worth discussing with your lawyer and accountant before closing, since it can affect which rebate (if any) actually applies.
Is the rebate the same thing as a discount from the builder?
No. A rebate assignment reflects a government program the buyer would otherwise have had to claim directly — it isn’t a builder discount or incentive, even though it can look similar on a closing statement.
