If you've been sitting on the fence about a new-construction purchase anywhere in Ontario, the Ontario government just gave you one of the strongest financial incentives in a generation to get off it.

On March 25, 2026, the province announced the most significant overhaul of the New Housing Rebate since HST was introduced on residential property. For a twelve-month window, buyers who sign an Agreement of Purchase and Sale between April 1, 2026 and March 31, 2027 can recover up to $130,000 in combined federal and provincial HST on a newly built home - a dramatic jump from the old provincial cap of $24,000, and from a federal rebate that phased out entirely once a home crossed $450,000.

What Changed

Under the previous rules, the federal portion of the rebate phased out entirely once a new home crossed the $450,000 mark, and the provincial portion was capped at just $24,000 - which in most Ontario markets meant the relief was modest at best. The enhanced structure now scales with price:

  • Homes up to $1,000,000 qualify for the full 13% HST rebate - up to $130,000 combined.
  • Homes between $1,000,000 and $1,500,000 remain capped at a maximum $130,000 rebate.
  • Homes between $1,500,000 and $1,850,000 see the rebate decline proportionally as price rises, easing down to a floor of $24,000 - the old maximum - at $1,850,000.

The federal government is covering its 5% portion while Ontario is funding an enhanced 8% provincial rebate, a major step up from the previous $24,000 provincial cap. Together, that's real money back in a buyer's pocket at closing - money that can be the difference between qualifying for a mortgage and walking away.

Rebate in Action: Three Examples

  • $1,000,000 home: Falls entirely within the full-rebate band. HST payable is $130,000, and the entire amount is recoverable - full 13% relief, no phase-out.
  • $1,350,000 home: Still within the $1,000,000 to $1,500,000 band, which caps out at the maximum rebate regardless of exact price within that range. This buyer also recovers the full $130,000, even though the home costs $350,000 more than the first example.
  • $1,700,000 home: Falls in the $1,500,000 to $1,850,000 phase-out band, where the rebate declines proportionally down to a $24,000 floor at $1,850,000. At this price point, the rebate works out to roughly $69,400 - meaningful, but well below the maximum. A buyer just $150,000 higher, at $1,850,000, would still receive the $24,000 floor amount.

These figures are illustrative, based on the proportional phase-out described in the 2026 Budget. Buyers in the $1,500,000 to $1,850,000 range should confirm the exact calculation with their accountant or lawyer before relying on it for financing.

How the Phase-Out Works

Between $1,500,000 and $1,850,000, the rebate doesn't drop off a cliff - it declines in a straight line as price rises, but it never falls below a floor. Think of it as a $350,000-wide band: at the bottom ($1,500,000) a buyer still gets the full $130,000, and at the top ($1,850,000) the rebate eases down to $24,000 - the old maximum - rather than to zero.

The math: the rebate slides between $130,000 and that $24,000 floor across the band, so rebate = $24,000 + $106,000 x (1,850,000 - purchase price) / 350,000.

Plug in $1,700,000 and there's $150,000 of room left in the band out of that $350,000 span, or about 43 percent. That's $24,000 plus 43 percent of the $106,000 sliding portion, which works out to roughly $69,400 - the figure used in the example above.

A few more reference points within the band: a $1,600,000 home lands at roughly $99,700, and a $1,800,000 home at roughly $39,100. As a rule of thumb, every $35,000 increase in purchase price within this band costs a buyer roughly $10,600 in rebate - until you hit the $24,000 floor.

That floor is written into the rules: any new home that would have qualified for the old maximum $24,000 provincial rebate will still receive at least that amount under the expansion - so a buyer in the phase-out band, and even above $1,850,000, never ends up worse off than they would have been under the previous rules.

This is a straight-line approximation based on how the 2026 Budget describes the phase-out as declining proportionally. It hasn't been confirmed against final regulation text, so treat it as directionally correct rather than exact, and verify with an accountant before using it in a financing decision.

Is There a Funding Cap?

The program is structured as an eligibility-based entitlement, not a capped fund - there's no first-come, first-served mechanism, and qualification depends on the Agreement of Purchase and Sale date, not on remaining funding. The province has projected the program will cost roughly $2.2 billion in tax relief over its life, but that's a budget forecast, not a legislated ceiling that would end the rebate early. The real risk is legislative rather than budgetary: like any tax measure, it could still be narrowed or wound down if the province amends it, so it's worth watching for updates rather than assuming the window runs its full course.

Who Qualifies

The rebate is available to eligible individual buyers purchasing or building a new home as a primary residence, and it applies broadly: detached and semi-detached houses, townhomes, condominium units, duplexes, co-op housing units, and even mobile or floating homes. Two dates matter most for eligibility: the Agreement of Purchase and Sale must be signed within the twelve-month window, and construction must commence by December 31, 2028 and reach substantial completion by December 31, 2031 - so this isn't limited to homes closing next year. Pre-construction buyers locking in a 2026 or early-2027 deal on a project with a multi-year build timeline can still capture the rebate.

What About Investors and Rentals?

The enhancement isn't only for people buying a home to live in. Ontario is also strengthening the New Residential Rental Property Rebate over the same window, so investors and landlords buying a qualifying new build to rent out can benefit too. The eligibility details and rebate math differ from the owner-occupier stream, so if you're purchasing a new home as a rental or investment, confirm your specific numbers with your accountant before you sign.
