1. Ontario Has Announced a Major HST Rebate Expansion — And It’s Likely Coming
On March 25, 2026, the Ontario government announced a proposal to effectively eliminate the full 13% HST on qualifying new homes, with potential savings of up to $130,000.
This is a major policy move, and in practical terms, it appears to be a direct response to the federal rebate we discussed yesterday.
While the announcement is framed as a proposal within the 2026 Budget (meaning it is not yet enacted law), the level of detail and coordination with the federal government strongly suggests this is not a tentative idea — it is a policy direction that is likely to move forward.
Why this matters: We are now looking at a coordinated federal–provincial effort to materially reduce the tax burden on new housing. If implemented as described, this will have a real impact on affordability, pricing, and how new construction deals are structured.

2. The Timing Signals Are Strong — But the Mechanics Are Not Final
Ontario has indicated that the program would run from April 1, 2026 to March 31, 2027.
At the same time, the province has stated it intends to align with the federal program’s effective date of March 20, 2025 for agreements of purchase and sale.
That combination suggests a likely outcome:
- The program may be funded starting April 2026
- But could apply to agreements signed as early as March 20, 2025
That said, the key implementation details are still unknown. We do not yet have confirmation on how eligibility will be determined — whether by agreement date, closing date, construction status, or a combination of these factors.
Why this matters: The direction is clear, but the mechanics are not. This is where the real-world application of the rebate — and potential pitfalls — will ultimately be decided.

3. Practical Guidance Right Now: Understand the Trade-Offs
The federal rebate we discussed yesterday is active and available today.
The Ontario rebate is not yet operational — but it is also not something to ignore.
For buyers and professionals dealing with existing or pending agreements, there are now two realistic paths:
- Wait-and-see approach: Some may consider delaying or unwinding a transaction (where possible) to preserve the opportunity to clearly fall within whatever final rules Ontario adopts. This approach prioritizes certainty of eligibility, but comes with obvious deal risk.
- Proceed-now approach: Others may choose to move forward with their transaction as planned, with the understanding that the Ontario rebate may ultimately apply — particularly if the province follows through on its stated intention to align with the March 20, 2025 effective date — but without any guarantee.
Why this matters: This is no longer just a legal question — it is a strategic one. Each option carries risk, and the right choice will depend on the specific deal, timing, and risk tolerance of the parties involved.
Bottom line
This is one of the most significant housing policy developments we’ve seen in recent years.
The direction is clear: meaningful tax relief on new housing, supported by both levels of government.
The details, however, are still coming — and that is where deals will either be protected or exposed.
