HST Rebate for New Builds in Ontario (2026): What Ottawa Homebuyers Should Know
If you've been waiting on the sidelines because new builds felt out of reach, this update matters. As of April 1, eligible buyers in Ontario can access enhanced HST relief on qualifying new homes, and for many buyers in Ottawa that can materially change affordability.
in total relief discussed publicly for eligible transactions.
What changed?
The updated rebate framework reduces the impact of Ontario's 13% harmonized sales tax on qualifying new homes. According to reporting from the Ottawa market, buyers are already changing their search strategy based on this update.
Some shoppers who were previously focused on resale homes are now reconsidering new builds, because the tax relief improves both total cost and mortgage qualification.
How much could the rebate be worth?
The key number discussed publicly is up to $130,000 in total relief for eligible transactions.
- Up to $1MEligible new homes up to $1,000,000 may qualify for the full relief.
- $1M–1.5MNew builds between $1,000,000 and $1,500,000 may still qualify, up to the same cap.
In practical terms, mortgage professionals in-market are saying some buyers who previously struggled to qualify are now in a stronger position.
Why this matters in Ottawa specifically
Ottawa has a wide range of buyer profiles right now: first-time buyers, families moving up, and owners downsizing. This rebate can help all three groups, especially when combined with clear planning around lot, location, and build type.
That said, buyers should still evaluate total project economics, not just sticker price. Development charges, closing costs, and financing structure all still matter.
What to watch out for
The rebate can be meaningful, but it's not a universal solution. Resale dynamics, neighbourhood inventory, and builder timelines can still shift fast. And depending on the property and municipality, development-related costs can still be substantial.
In Ottawa, one-time development charges on certain property types can still range materially by location. Provincial discussion around reducing those charges may help, but buyers should underwrite based on what is currently known and confirmed.
Bottom line
This is one of the most significant housing incentives buyers have seen in years. For eligible Ottawa buyers, it can open doors that were previously closed, especially for new builds where qualification was the main blocker.
If you're evaluating whether to build new, run the numbers early and get project-specific clarity before making assumptions.
