## What the Ontario Regulations Change (HST Housing Rebates)
The **Regulations Amending the New Harmonized Value-Added Tax System Regulations, No. 2 (Ontario) (P.C. 2026-610)**—made June 12, 2026 and effective April 1, 2026—modify eligibility and rebate calculation for residential complex purchases in Ontario.

Key changes include:
- Expanding the definition of eligible residential complex purchases—including certain agreements entered into after March 2026.

- Setting a **maximum total rebate cap of $80,000** or the total Ontario HST paid, whichever is lower. ([canada.ca](https://www.canada.ca/en/department-finance/programs/tax-policy/regulations-amending-new-harmonized-value-added-tax-system-regulations-2026-610.html?utm_source=openai))
- Adjusting application deadline rules, including stricter timelines for when the agreement of purchase and sale must be entered into to qualify.

## Compliance Steps for Buyers & Builders
To ensure claims succeed under these rules, homeowners, buyers, and builders should:
* Confirm that your agreement of purchase & sale is entered between **April 1, 2026 and April 1, 2027**, if applicable for rebate eligibility under the new rules. ([canada.ca](https://www.canada.ca/en/department-finance/programs/tax-policy/regulations-amending-new-harmonized-value-added-tax-system-regulations-2026-610.html?utm_source=openai))
* Check that purchase price (total consideration) is under the $1,850,000 threshold for the rebate to apply under those enhanced sections. ([canada.ca](https://www.canada.ca/en/department-finance/programs/tax-policy/regulations-amending-new-harmonized-value-added-tax-system-regulations-2026-610.html?utm_source=openai))
* Ensure paperwork is filed on time: the application under section 256.21 must be submitted as required. The deadlines, depending on when construction or substantial renovation is completed, can affect eligibility. ([canada.ca](https://www.canada.ca/en/department-finance/programs/tax-policy/regulations-amending-new-harmonized-value-added-tax-system-regulations-2026-610.html?utm_source=openai))
* For shared or complex ownership structures, only one individual or group may claim the Ontario portion of the rebate for the residential complex.

## Practical Examples
**New home purchase example:** Sarah contracts a builder in June 2026 to buy a residential condominium unit. Since her agreement is after March 31, 2026 and construction substantially completes before April 2027, she may claim under the new enhanced rebate rules, provided the fair market value is under $1,850,000. But the maximum rebate she can receive for the Ontario portion is capped at $80,000.
**Timing issue for improvements:** If a builder substantially renovates a complex starting before April 2026 but completes it after March 2026, certain transitional rules apply to determine which rebate provisions and timelines you are under. Always verify which version applies.
## Actionable Advice for Buyers and Professionals
- Before signing, consult a tax or real-estate lawyer to ensure your agreement dates align with eligibility windows.
- Keep detailed documentation of all agreements, construction dates, and valuation assessments in case CRA or Finance audits your claim.
- Builders selling multiple units should educate purchasers about eligibility and assist with rebate application packages.
- When values approach the rebate cap or purchase price thresholds, carefully model potential savings or shortfalls.
Getting these filings right means you can leverage the rebate fully—errors or missed timelines could disqualify large portions.
