Ontario’s HST Rebate Is Driving New Home Prices Higher Without Sales

Ontario real estate developers are raising prices despite facing some of the weakest demand on record. The reason? The Government of Ontario’s expanded Harmonized Sales Tax (HST) relief. The thinly veiled bailout is already undermining policymaker narratives few believed, with experts warning the “savings” are being rolled into higher new home prices. 

Ontario’s Latest Builder Bailout: HST Rebates

Among the builder incentives termed “bailout” measures by at least one bank is the HST rebate expansion. At the end of March, Ontario temporarily removed the 13% HST on new homes up to $1 million, capped at a flat $130,000 up to $1.5 million before phasing out on a sliding scale. The rebate applies to pre-construction agreements signed between April 1, 2026 and March 31, 2027. 

Eligible buyers include primary residence purchasers (who must start construction by December 31, 2028) or investors buying rental properties that are substantially completed by December 31, 2029. It doesn’t even have the facade of first-time buyer relief. It’s a straight bailout for the investor-dominated segment.

That may sound like great news for buyers trying to navigate a deeply unaffordable market. However, prospective buyers who thought they were about to receive help found themselves facing higher prices.

Ontario Home Builders Have Raised Prices To Absorb HST Rebate 

An X post seen by over 200k people shows a person claiming that one builder’s prices jumped from $1.3 million to $1.45 million—an 11.5% increase post-announcement. The poster’s take: “There is no rebate.” Some Realtors dismissed it as an isolated incident, but an army of real estate professionals are seeing similar price hikes in Ontario.

“Some builders are already increasing prices. Others may start holding offers on inventory units,” warns Toronto Realtor Rachna Purohit. “The rebate that was supposed to HELP buyers could actually end up benefiting builders instead.”  

Mortgage broker Sasitha Suyatharan observed a similar trend: clients eyeing a $950k home saw it jump to $1.05 million post-HST announcement—a 10.5% surge. She warns buyers may think they’re getting a deal, but that’s not necessarily the case. 

There’s also Toronto Realtor Gurleen Kamboh, whose clients saw the $1.4 million home they were looking at jump to $1.6 million—14.3% higher. 

This isn’t just a Toronto problem. Ottawa-based Realtor Charles Khouri explains, “I’ve already seen builders start adjusting prices” in response to the rebate. He warns that any “savings” may get absorbed into higher prices. 

Over in Kitchener, real estate investor and Realtor Stacey Chan is warning buyers this isn’t a win. “This rebate? It’s a lifeline for them, not just for you,” she says bluntly. “Just because there’s a rebate doesn’t mean you pocket the savings. Builders can tweak prices or incentives, so the real benefit might never reach you.”

She adds perspective for investors: pre-construction is a long game. “You’re locking in today, but closing could be three, four, even five years away. In that time, interest rates, fees, and the whole market can shift.”

A market that was frozen is suddenly more expensive, while demand sits near record lows. To grasp why builders are raising prices in a frozen market, there are two important things to understand: how home prices actually work, and the mechanics of buying new construction.  

The Illusion of Affordability: How Leverage Drives Home Prices

Home prices aren’t based on supply and demand for housing units—they’re based on supply and demand for credit. The Bank of Canada found that lower rates didn’t improve affordability; they increased leverage, helping buyers absorb higher prices. People stopped thinking in terms of what a home costs and started thinking in terms of monthly payments. Rather than saving money, they committed to handing over more principal to the sellers. 

Grocery bills are surging. Would financing your weekend grocery bill over 10 years make it more affordable? Of course not. That’s exactly how housing works in countries like Canada and the US. While affordability traditionally means multiples of income, state-backed markets lower the lender risk and shift pricing to borrower cash flow. How much leverage marginal buyers get determines the price.  

Falling input costs mean developers can lower prices—or pocket bigger profits. Price is ultimately what can be financed, plus or minus state incentives. Typically, taxes are treated as closing costs paid in cash out-of-pocket, which can’t be financed. But the industry found a workaround. 

The New Housing Rebate provided smaller HST relief for condos and subdivisions—and builders found a way to capture it. Builders advertised HST-inclusive prices and required buyers to sign over their rebate rights. This eliminated the sticker shock of paying HST on top of the purchase price, and let many roll taxes into the mortgage. The recent HST expansion is drawing from the same playbook. 

Mortgage broker JD Lee breaks it down: “On the surface, it sounds like a great benefit—but in reality, it functions more like a builder bailout. 

Step 1: Government -> Provides the rebate

Step 2: Builder -> Factors the rebate into the purchase price upfront 

Step 3: Buyer -> Effectively pays it back to the builder.”

“The rebate is not truly a consumer benefit—it’s a pricing tool controlled by builders,” warns Lee. “There’s a high likelihood that it’s already baked into the price.” 

That HST you can’t finance? Now you can. 

Financing A Bailout Drives Borrowing Costs Higher, Undermines Long-Term Real Estate Demand

Ultimately, this is good for demand, right? Not exactly. Looking beyond whether new homes should be subject to HST, the current implementation undermines long-term demand. Ontario’s net debt per capita is the third-highest of any province, and its aggregate deficit is set to be the largest. Unlike a province running a surplus with low debt, any HST revenue forgone means an unpaid liability to finance. Since credit is a market, this provides upward pressure on bond yields. 

This won’t just drive the cost of financing a home higher. It applies upward pressure on all borrowing costs. A second on the lips, forever on the bps. The government is borrowing, so you don’t have to. 

Ontario’s new construction market has priced out end users, and is now dominated by investors. This borrowing is effectively a wealth transfer from the average person—and the province’s long-term success—to builders, who can now technically “buy” their own inventory for rentals and collect the HST. 

The rebate’s timing is also suspicious. It comes shortly after Canada’s bank regulator threatened banks with violating the Bank Act by using stale blanket appraisals to inflate the asset value securing mortgages. If those taxes are rebated and rolled into the price, the market is suddenly 10-15% higher, providing a convenient but questionable solution to offset the need for inflated appraisals that overlooked zero equity in some cases. 

Ultimately, while the government and its select group of insiders are shoring up demand temporarily, it isn’t enough to restore the market. It’s a bailout that delays revealing the structural issues that remain.
