How the Ontario HST Rebate Saves You Money
On May 5, 2026, the province introduced the HST Relief Implementation Act to build the official framework for this 13% tax relief program. If you buy a new home, the savings can be substantial. The program provides a sliding scale of rebates based on the purchase price of your new home.
When you purchase a home valued up to $1.5 million, you can receive the maximum rebate of $130,000. For homes priced above $1.5 million up to $1.85 million, the rebate gradually phases down to a minimum of $24,000. This sliding scale ensures that middle-class buyers receive the most significant relief while still offering some support for higher-end purchases.
For a clear picture of how this looks across different purchase prices, review the table below:
| Home Purchase Price | Maximum Ontario HST Rebate | Minimum Down Payment Required |
|---|---|---|
| Up to $1,500,000 | $130,000 | $115,000 (based on $1.4M price) |
| $1,600,000 | $100,000 | $320,000 (20% uninsured) |
| $1,700,000 | $70,000 | $340,000 (20% uninsured) |
| $1,850,000 or more | $24,000 | $370,000 (20% uninsured) |
Before you put pen to paper, using a mortgage calculator in Ontario can help you see how these tax savings and down payment rules impact your monthly budget.
Who Qualifies for the Ontario HST Rebate?
To qualify for this rebate, timing is everything. You must sign your agreement of purchase and sale between April 1, 2026, and March 31, 2027. This narrow one-year window means you need to act quickly if you want to capture the full benefit of the pre-construction HST rebate.
But how does this program interact with other government incentives? For example, the federal government recently passed the First-Time Home Buyers’ GST/HST Rebate, which received Royal Assent on March 12, 2026. This federal rebate gives eligible first-time buyers a full rebate of the GST on new-build homes priced up to $1,000,000, and a partial rebate up to $50,000 for homes between $1,000,000 and $1,500,000.
Federal eligibility requires a four-year look-back period. This means neither you nor your spouse lived in a home you owned in the current calendar year or the four preceding years. Combining these programs can lead to massive total savings, but you must ensure you meet the strict criteria for both.

GTA Market Heat and Pre-Construction Buying
The introduction of this rebate has already sent shockwaves through the local real estate market. In April 2026, which was the very first month of the rebate window, single-family home sales in the GTA surged to 901, up from just 241 in April 2025. Buyers in areas like Markham, Vaughan, and Ajax are jumping on these opportunities before inventory disappears.
With demand spiking, builders are moving fast. But pre-construction buying comes with unique timeline challenges. Sometimes, your closing date gets delayed, or you need to close on your new home before your current property sells. That is where having access to flexible bridge financing in Ontario becomes highly valuable.
Our team at Canadian Mortgage Services has been helping local buyers since 1988. We have relationships with over 40 lenders, meaning we can shop around to find the best terms for your specific situation. We can also share real-world stories about how local families save money by restructuring their existing debt to afford a brand-new home.
Financing Your New Build with Smart Mortgage Strategies
Securing a mortgage for a brand-new home involves some rules that differ from standard resale properties. One major advantage of buying a newly constructed home is the amortization limit. While standard insured mortgages are capped at a 25-year amortization, a 30-year amortization is available to all buyers of newly constructed homes, regardless of whether you are a first-time buyer or a seasoned investor. This change took effect on December 15, 2024.
Keep in mind that 30-year insured mortgages carry a slight premium surcharge of 20 basis points, but the lower monthly payments can make a massive difference in your cash flow.
Let’s also look at the high-ratio mortgage insurance rules. The maximum home price eligible for this insurance is $1,500,000. If your new home costs $1.5 million or more, you must put down at least 20% because mortgage default insurance is not available.
Planning your purchase price carefully is essential. For a $1,400,000 home, your minimum down payment is $115,000 ($25,000 for the first $500,000 plus $90,000 for the remaining $900,000). If you go up to a $1,500,000 home, your minimum down payment jumps to $300,000 (20%). That is a massive leap, so planning your purchase price carefully is essential.
We do not disappear after closing. We work with you to ensure your mortgage fits your long-term goals. Whether you are buying in Whitby, Oshawa, Milton, or Brampton, we are here to guide you through every step of the process.
