The headline everyone is quoting is $130,000, and that number belongs to somebody buying a million dollar house in Oakville. Here is what the same rule is actually worth on a Windsor new build, why it hands more money to a move up buyer than to a first time buyer, and what happens if the city's 70 per cent development charge cut gets approved on top of it.
A new build priced at $600,000 in Windsor now carries $78,000 of HST relief. Not a deduction, not a credit you claim against something else years from now. The full thirteen per cent back, and in most cases the builder applies it on your closing statement so the money never has to leave your account and come back.
The figure you have seen in the headlines is $130,000. That number is real, but it belongs to somebody buying a million dollar house in Oakville. I have not found anyone who bothered to work out what the same rule is worth here, where a new build runs somewhere between $450,000 and $700,000. So that is what this is.
The rebate mechanics below come from CRA Notice 346, which sets out the Ontario enhanced new housing rebate. The market figures come from the July 2026 residential report the Windsor-Essex County Association of REALTORS publishes through the CREA MLS system. The development charge material comes from the City of Windsor's council report and the terms of the federal and provincial program the city applied to.
The legislation cleared in June and was made retroactive to April 1, so anyone who signed in the spring while the rules were still being finalised is covered. If you signed a new build agreement this year and nobody has raised this with you, that is a conversation to have with your lawyer this week rather than next month.
Since the whole 13 per cent comes off anything under a million dollars, the arithmetic is refreshingly simple for once. Take the price before tax and multiply.
Hold those against the resale market for a second. The average Windsor-Essex sale in July closed at $541,019 and the median at $502,500. The rebate on a comparably priced new build is worth somewhere around $65,000, which is roughly what a buyer in this region spends on a down payment. That is the scale of it.
Here is where it gets genuinely interesting, and where I think most of the coverage has it backwards.
The instinct is that a housing affordability measure exists for first time buyers. This one quietly hands more money to the move up buyer, and the reason is buried in how the payment interacts with a rebate that already existed.
Run a $600,000 build through it twice. A repeat buyer used to get the Ontario new housing rebate capped at $24,000, and nothing federally, because that rebate phases out entirely above $450,000. Total relief, $24,000. Under the new rules the same person gets $48,000 provincially plus $30,000 through the affordability payment, so $78,000. They are $54,000 better off than they were in March.
Now the first time buyer. They already had the first time buyers' GST rebate that came in during 2025, which covered the full federal 5 per cent on a home up to a million dollars, so they were sitting at $30,000 federally plus the same $24,000 provincially. Total relief, $54,000. Under the new rules their provincial share doubles to $48,000, but the affordability payment is explicitly reduced by whatever they already claim federally, which zeroes it out for them. They land at the same $78,000. Better off by $24,000.
Same house, same cheque at the end, and the person who has owned before picks up an extra $30,000 of benefit relative to where each of them started. I have never seen an Ontario housing program work in that direction. It matters here because a large share of the people I sit down with are not first time buyers at all. They are in their fifties, the kids are gone, and they want a smaller place with no stairs. I wrote about how badly that group gets squeezed on bungalows earlier this summer, and this is the first policy in years that points money at them instead of past them.
Every affordability program I have explained to a client for the last decade started with the words first time buyer. This one doesn't, and the people it quietly favours are the ones nobody built it for.
The rebate is settled law. What sits alongside it is not, and I want to be careful about how I describe it, because a fair number of people around here have already been told it is a done deal.
Windsor currently charges about $45,000 in development charges on a new single family home. That cost lands in the builder's price whether you ever see the line item or not. In June council voted unanimously to cut that charge by 70 per cent for three years, which would take roughly $31,500 out of the cost of building a house here. The program asked municipalities for a minimum of 30 per cent and most landed on 50. Windsor went to 70, further than any other municipality in the province.
The catch is that the cut only happens if the city's application succeeds. Windsor asked for $49.89 million from the $8.8 billion Canada-Ontario Development Charge Reduction Program against five shovel ready projects worth $122.8 million in total, the largest of which is $31.5 million of infrastructure for the new hospital at Cabana and the Ninth Concession. Municipalities were told to expect an answer by August 15. That date has come and gone, and the most the city has confirmed publicly is that the ministry received the paperwork. City staff estimated the reduction could unlock close to 2,933 units if it lands.
This is worth knowing if you are shopping outside the city, because the towns did not all move the same way and they were not starting from the same place.
Lakeshore, Kingsville, LaSalle, Essex and Tecumseh all applied at 50 per cent. Amherstburg looked at the arithmetic and opted out. The starting charges vary a lot too. Kingsville sits around $20,200 on a new single or semi, Tecumseh around $36,000, against Windsor's $45,000. So a 50 per cent cut in Kingsville moves about $10,100 while a 70 per cent cut in Windsor moves $31,500, and the gap between building in the city and building in the county narrows considerably if both go through.
None of it means much in isolation, so here is the context that makes it real. July closed with 2,307 active listings across Windsor-Essex, the highest for that month in more than a decade, and 4.4 months of supply against a long run July norm of 2.7. I went through what that softness means for each side of the table a couple of weeks ago.
A new build has always carried a premium over resale, and in a market this well supplied that premium is usually enough to end the conversation. Strip the HST out and the premium mostly disappears. A $600,000 new build with $78,000 back competes on price with a resale house in the low $500,000s, except it comes with a warranty, current code, and nothing to fix for fifteen years. That comparison did not exist in March.
Alyssa Ismail, who runs the local board, has been making a related point publicly for months, which is that the thing this region is short of is the missing middle. Two or three bedrooms, one bath, small yard, priced for somebody just qualifying. Her line that stuck with me was that being $10,000 or $20,000 over on price in this market means the showings simply stop. Take $31,500 of development charges and the entire HST off a starter build and that is not a rounding error, that is the difference between a product existing and not existing.
For a decade the new build conversation in Windsor ended the same way, which is that the resale house down the street was eighty grand cheaper. That sentence stopped being true this spring and almost nobody has noticed yet.
I would rather list the soft spots myself than let you read the last few sections as a recommendation.
That last point is the one I would sit with. A demand side incentive arriving while supply is down twenty two per cent is how you get prices absorbing the benefit instead of buyers keeping it. The window where this is genuinely a buyer's advantage is the window before builders work out that everyone shopping has an extra seventy grand of purchasing power.
Worth saying plainly that this does not make a new build the right answer for everybody. Most of my buyers still end up in resale, and with 4.4 months of supply the negotiating room on an existing house is the best it has been in years. What has changed is that new construction now deserves to be on the list, and for the last decade it mostly did not.
If you are weighing a new build against selling what you have now, the piece to establish first is what your current place is actually worth, because that number decides everything downstream. A free home evaluation covers three groups: what closed recently near you, what you would be competing with if you listed, and the ones that came off the market without selling. You get a range and the reasoning behind it, and if the honest answer is to wait, I will tell you that instead.
Buying rather than selling? Set your own filters and see what fits, or start with what is available under $500,000 if that is closer to your range. The buyer's walkthrough from financing to closing lays out the order of operations, and every first time buyer program still on the table this year covers the rest of what you can claim.
Somewhere specific in mind? Start with Windsor, LaSalle, Tecumseh, Lakeshore or Kingsville. Or call me and we will work through your actual purchase instead of a worked example, because the difference between $58,500 and $91,000 comes down to details that are specific to you.
