A New-Home Rebate Isn’t Cash on Closing Day: What Ontario Buyers Should Check

What the relief is, in two pieces

Ontario's temporary expanded HST relief on new or substantially renovated homes has two components, and they are paid by two different governments.

According to the Province of Ontario's own page on the program, the first component is the Ontario Enhanced New Housing Rebate, which provides up to $80,000, equal to up to 100% of the 8% provincial portion of the HST. The Canada Revenue Agency administers it. The second is the Ontario New Home Affordability Payment, a top-up of up to $50,000, equal to up to 100% of the 5% federal portion. Ontario administers that one.

Together, the province says, they effectively relieve the full 13% HST on a new or substantially renovated home valued up to $1 million. That is where the $130,000 figure in the headlines comes from: $80,000 plus $50,000. It is a ceiling, not a typical outcome, and the amounts decline above $1 million.

Two details trip people up. The top-up payment is reduced by the federal portion of any HST rebate you are entitled to claim, including the federal first-time home buyers' rebate, so it is not an extra $50,000 stacked on top of a full federal rebate. And you must first be eligible for and receive the Ontario rebate to receive the top-up. Who qualifies, and the timelines, are covered in our earlier piece, Ontario's new-home tax rebate: who actually qualifies.

The question that matters on closing day

Most coverage stops at eligibility. For a buyer, the practical question is when the money arrives. Writing in Canadian Mortgage Trends on 5 October 2026, mortgage broker Ross Taylor put it plainly: a buyer can qualify for a large rebate and still have to produce that money on closing day.

Ontario's page describes the two paths. If the builder pays or credits the relief to you, the builder submits the rebate application for you. If you bought from a builder who did not credit it, or you did not buy from a builder, and you paid the HST, you fill out the application yourself and are repaid afterward.

Taylor's article also reports that CRA advises applicants to anticipate 120 days for processing, that this is not a guaranteed payment date, and that a claim can be audited, adding up to six months. He adds that CRA expects to begin processing claims for the Ontario enhanced rebate once system changes are in place in fall 2026. Those are his reading of CRA's guidance, and timelines can change, so confirm the current position with your lawyer or the CRA before you plan around a date.

How your lender may treat a rebate

The second question is how the lender counts it. Taylor notes that Sagen's current underwriting guidance says that where the borrower assigns the GST/HST rebate to the builder, the purchase price submitted for mortgage purposes is the price net of the rebate. In plain terms, the rebate can reduce the price and the cash required to close without becoming part of your equity.

That matters for a down payment. A rebate that shrinks the price is not the same as $80,000 of your own savings, and a lender or insurer may not accept it as such. Conventional lenders may have their own approach. On an insured file, the sensible step is to confirm treatment with the lender and the mortgage insurer before the deal is structured, not after.

It also connects to the rest of your closing costs. If you are comparing the full list of items due on the day, our line-by-line closing cash guide is the place to start, and how deposits and mortgages work on new construction covers the staged deposits that come before it.

Questions to put to your builder and lawyer

• Will the builder credit the HST relief on the statement of adjustments, or will I pay the tax and claim it myself?
• If I claim it myself, what amount do I need to have available on closing day, and where will it come from until it is repaid?
• Does my lender count a credited rebate as part of my down payment, or only as a reduction in price?
• Do I still qualify if my closing slips, given the dates attached to the program?
• Who is preparing the rebate application, and who confirms the amounts?

Neither a broker nor this article can confirm your eligibility. A real estate lawyer or a qualified tax adviser can. The value of raising the questions early is that the answers shape how much cash you set aside, and that is a planning decision rather than a tax one.
