A newly expanded HST rebate program, introduced in 2026, is cutting the cost of new construction homes by as much as 13 percent, creating a short window where buyers can save tens of thousands on a purchase. The result is a noticeable shift in momentum, with increased interest in pre-construction and newly built properties across the city.
At the centre of the buzz is the scale of the savings. Under the temporary program, buyers can receive up to $130,000 back on a new home, effectively eliminating the full HST on properties priced up to $1 million.
For homes priced between $1 million and $1.5 million, that maximum rebate still holds, while higher-priced homes receive a reduced but still significant break.
It’s a sharp departure from previous programs, which were more limited in scope and often restricted to first-time buyers. This time, eligibility is broader. The rebate applies to most buyers, including investors, as long as the property is a newly built or substantially renovated home.
The timing is just as important as the amount. The program is only available for purchase agreements signed between April 1, 2026 and March 31, 2027, creating a defined one-year window that is already influencing buyer behaviour.
In practical terms, that means urgency.
For many buyers, the rebate can represent the equivalent of a down payment or years of savings. On a $900,000 home, the savings could exceed $100,000, fundamentally changing affordability calculations and mortgage eligibility.
That shift is beginning to show in Ottawa’s new build market, particularly in suburban areas like Barrhaven, Kanata, and Orleans, where much of the city’s housing supply is concentrated.
But the impact is not evenly distributed.
The rebate applies only to new construction, not resale homes, which could widen the gap between the two markets. It also depends on timing. Buyers who miss the window may face significantly higher costs once the program ends.
For now, though, the effect is clear. The combination of lower effective prices and a limited timeframe is creating a sense of momentum that the market has not seen in recent months.
Whether that momentum lasts is less certain.
The rebate is designed as a temporary measure to stimulate housing activity, with projections suggesting it could support thousands of new builds across Ontario. But once the window closes, the market will have to adjust again.
In that sense, Ottawa’s housing market is entering a moment that is both opportunity and pressure.
For buyers, it may be one of the most financially advantageous windows in years. For the market itself, it is a test of how much demand can be unlocked when affordability shifts, even briefly, in the other direction.
