Ask what HST rebate a 2026 Ontario new-home buyer gets and the honest answer is a stack, not a number. Three newer programs now sit on top of the two long-standing new housing rebates, each with its own buyer, its own price ceiling and its own agreement-date window. And the catalogue you are reading prices 29 of its 63 priced records on a basis that already nets an estimated rebate out of the sticker — so the stack is not background reading here; it is printed, in effect, on 29 project pages. This post sets out the programs as the Canada Revenue Agency and Ontario publish them, then reads two real catalogue prices through them. It describes the mechanics generally; it is not tax advice for any specific purchase, and the CRA pages linked below govern.
The stack, layer by layer
| Program | Worth up to | Who, and on what dates |
|---|---|---|
| Ontario enhanced new housing rebate (ENHR) — the 8% provincial part | 100% of it, to $80,000 | Any eligible buyer — it is not a first-time-buyer program. Builder agreement signed on or after April 1, 2026 and on or before March 31, 2027; home for the buyer’s or a relation’s primary residence; price under $1,850,000 |
| Ontario New Homes Affordability Payment (ONHAP) — the 5% federal part | $50,000 | Paid by Ontario to buyers entitled to the ENHR. Reduced by any federal rebate the buyer can claim, so the same tax is not returned twice; no separate application |
| First-time home buyers’ GST/HST rebate, with Ontario’s first-time buyer rebate — both parts | $50,000 federal, plus up to $80,000 provincial as a top-up | First-time buyers only. Builder agreements signed on or after March 20, 2025 and before 2031 |
| The long-standing new housing rebates — both parts | $6,300 federal; $24,000 Ontario | The pair the closing-costs post on this site works line by line: the federal rebate phases out between $350,000 and $450,000 of price; the Ontario cap has no price phase-out |
One layering rule matters: the ENHR figure is a combined ceiling, not an addition. The enhanced rebate and the standard Ontario rebate together return up to $80,000 of the provincial part — a buyer in the window does not collect $80,000 and then $24,000 more.
What the stack is worth by price
For an agreement signed inside the enhanced window (April 1, 2026 to March 31, 2027), the CRA’s published bands are:
| New home price | Combined enhanced relief |
|---|---|
| Up to $1,000,000 | The full 13% — up to $130,000 ($80,000 provincial + $50,000 federal) |
| $1,000,000 to $1,500,000 | Capped at $130,000 |
| $1,500,000 to under $1,850,000 | Reduced from the ceiling |
| $1,850,000 and over | No enhanced rebate — the standard Ontario rebate of up to $24,000 is what remains |
The worked example is easiest to see against the post this one sits beside. Closing costs on a $700,000 pre-construction home computes the old stack on a $700,000 price: $91,000 of HST, the federal rebate fully phased out at that price, the Ontario rebate returning $24,000 — a net HST line of $67,000. Sign the same $700,000 purchase inside the enhanced window, as an eligible buyer, and the arithmetic changes completely: the provincial part ($56,000 at this price) returns in full under the ENHR, and the federal part ($35,000) returns through the affordability payment — or, for a first-time buyer, through the first-time buyers’ rebate with Ontario’s top-up of the provincial part reaching the same total. The full $91,000 is the ceiling case, and it is the province’s own published example at this price. Outside the window, a first-time buyer keeps their own stack (federal relief in full to $1 million, phasing out to $1.5 million — at $1.25 million the federal rebate is $25,000); a repeat buyer outside the window is back to the $24,000 Ontario line.
Reading a catalogue price through the stack
This is where the stack stops being a tax topic and becomes a price-reading skill. Every priced record in this catalogue carries a price basis — the builder’s own statement of what the figure already does about tax and rebates. Counted across the 63 priced records:
| Price basis on record | Priced records |
|---|---|
| After rebate — enhanced | 20 |
| After rebate | 9 |
| After credit | 1 |
| Taxes included in the price | 6 |
| Tax-free guaranteed | 1 |
| Net of HST | 1 |
| Standard | 1 |
| No basis stated | 24 |
Take Wildflowers in Kitchener: priced from $516,805, on the after-rebate-enhanced basis. Mattamy’s published basis description states that its prices include an estimated amount for the temporary Ontario enhanced new housing HST rebate. So the sticker has already spent one layer of the stack — an estimate of the provincial enhanced relief — before the buyer signs anything. What the buyer actually keeps turns on the same conditions as the program itself: an agreement date inside the window, the home as a primary residence, eligibility as the builder’s documents state it. A buyer who does not qualify is not holding a $516,805 home plus a rebate application; they are holding the agreement’s gross-up terms, which is why the basis line matters more than the number beside it. And nothing in that from-price has netted the 5% federal part: that layer reaches the buyer separately, as the first-time buyers’ rebate, as a builder credit of it at closing, or — for an ENHR-entitled buyer who is not a first-timer — as Ontario’s affordability payment. Cadence in Cambridge reads the same way at $649,990 — its price note records the detached homes from $769,990, both figures after applicable new home HST rebates.
First-time status is priced in twice
The first-time layer of the stack has a quieter echo inside this catalogue’s deposit data. NOMI Urban Towns publishes two deposit tracks: a standard ladder to 10%, and a first-time-buyer track to 5% on the same instalment rhythm. First-time status, in other words, changes both what a buyer pays the builder before closing and what the tax system returns after it — and a buyer comparing projects on the from-price alone sees neither effect. The worksheet exists for exactly this: your price, run through the layers that actually apply to you.
The honest gaps
- The program parameters above are as published by the CRA — Notice 346 for the enhanced rebate and affordability payment, the first-time buyers’ pages for the federal rebate and its Ontario top-up — at the time of writing. Programs built on agreement-date windows can be amended; the linked pages govern.
- Whether a specific buyer keeps a builder’s netted estimate is decided by the agreement and the buyer’s own facts. No catalogue record can state it, and none here tries.
- Twenty-four of the 63 priced records state no basis at all. For those, the only honest reading of the price is “before whatever the agreement says about tax” — which is a question for the project page’s enquiry form, not for a guess.
