Ontario has introduced a major change aimed at lowering the cost of newly built homes — and it’s one of the most meaningful affordability moves we’ve seen in years.

At a high level, this new framework targets two things:

• Reducing the tax on new homes
• Reducing the cost of building them

1) Ontario’s New Home HST Break

The headline change is simple: on eligible purchases, the province and federal government are moving toward significantly reducing — and in many cases effectively eliminating — the HST on new homes temporarily. In a market where taxes can add tens of thousands to the price of a new home, that is a very meaningful shift.

For eligible new homes priced at $1 million or less, the relief can be worth as much as $130,000, which is the equivalent of the full HST. Ontario has also said that the same $130,000 maximum would still apply to homes priced between $1 million and $1.5 million, recognizing that many new homes in Ontario now fall above the $1 million mark.

Above $1.5 million, the relief would begin to step down. It would decline gradually until about $1.85 million, where it would return to the current $24,000 level of HST relief that already exists under the pre-existing rebate structure.

Not just for first-time buyers

This is one reason the announcement is getting so much attention: it is not being positioned as only a first-time buyer measure. This expanded relief is for all buyers of new homes, including primary residences and residential rental properties.

The program is aimed at newly constructed homes, including unsold builder inventory, that are new, never occupied, and purchased directly from the builder.

Timing matters

Ontario’s current framework ties the relief to a specific timing window. Eligible agreements are expected to be signed between April 1, 2026, and March 31, 2027. Beyond that, the home also has to meet construction timing rules: construction must generally begin by December 31, 2028, and the home must be substantially completed by December 31, 2031.

So, this is not just about price. It is also about when the deal is signed and whether the project falls within the build timeline.

For anyone looking at new construction, this changes the conversation. A tax break of this size can materially reduce the effective cost of a home. It may also make some builder inventory more attractive and could help certain projects move ahead that might otherwise have struggled in the current environment.

2) Lower Development Charges

The second part of the plan focuses on something most buyers never see directly — development charges.

These are fees builders pay to municipalities to cover infrastructure, such as:

• roads
• water and sewer
• parks and services

Those costs are already built into the price of new homes.

What’s changing:

• $8.8 billion in combined federal and provincial funding
• Municipalities are expected to reduce development charges by up to 50%
• The reductions are targeted for three years
• Focused on municipalities covering the majority of Ontario’s population

Why it matters:

Development charges have become one of the biggest reasons new projects don’t move forward.

Lowering them:

• improves the economics of building
• helps stalled projects proceed
• supports more housing supply coming to market
• helps reduce the price of new builds by lowering a major underlying cost

This doesn’t show up as a rebate, but it directly impacts how new homes are priced because development charges are built into every new build.

3) The Bigger Picture

This is a two-part strategy:

• Reduce the cost to buy new homes
• Make it easier to build more of them

Both are needed. Because affordability isn’t just about price — it’s about supply and availability.

This new framework has the potential to meaningfully change the cost of buying a new home in Ontario. For buyers considering new construction, it creates a real opportunity — especially within the defined timing window.

Financing a New Build

Financing a newly built home can vary depending on whether you’re buying pre-construction or a completed new home, but either way, there are important differences compared to resale. Rakhi focuses on making sure you’re prepared for how timing and lender requirements can impact your financing:

• Understanding when your mortgage rate is set
  For pre-construction, your rate is often determined closer to completion. For completed homes, it works like a traditional purchase.
• Making sure your approval holds up
  With longer timelines, lenders reassess your financial position at closing — not just at the time of purchase. That means your income, debt levels, and credit score all need to remain strong throughout the process. Taking on new debt, missing payments, or changes to your credit can impact your approval or the rate you qualify for.
• Structuring your down payment properly
  Builder deposit schedules and final funding need to align with your overall financial plan.
• Knowing how the property will be valued
  The home must appraise at the purchase price at closing, regardless of when you bought.
• Keeping your options open
  Mortgage options can change, so having flexibility in your approach helps ensure you’re not locked into one path too early.

Work with Rakhi

A new build is a big decision — and there’s a lot more to it than just the price. Builder timelines, deposit structures, financing conditions, appraisal risk, rate holds, and how incentives like this apply — all of it can impact the outcome. That’s where working with someone experienced makes a difference. Rakhi helps you understand the full picture before you commit — what you qualify for, how the numbers work, and what to watch for so there are no surprises later.
