Short answer
Ontario new-home HST rebate planning depends on buyer type, agreement date, occupancy, price, and whether the rule path is confirmed or proposal-sensitive. The calculator keeps Ontario relief separate from federal relief and marks temporary/enhanced rules as verify-before-relying.

What this page helps you decide
Buyer wants to estimate Ontario new-home HST rebate eligibility and understand how proposed/enhanced rules interact with federal relief.
- Ontario enhanced 2026 rules are marked as proposed and verify-before-relying.
- Agreement date, buyer type, price, and occupancy assumptions affect which path is shown.
- The calculator keeps fallback new housing rebate estimates visible where relevant.
Documents to check
Where to find the answer
The goal is to replace rough assumptions with document-backed numbers before closing.
Agreement of purchase and sale
Confirms the signed date and whether the purchase falls inside the relevant window.
Tarion/HCRA addendum
Helps confirm critical dates, construction timing, and occupancy context.
Builder rebate schedule
Shows whether rebates are assigned, credited, held back, or claimed later.
Statement of adjustments
Shows what the buyer is actually being asked to fund at closing.
Existing Ontario rebate versus enhanced relief
The existing Ontario new housing rebate remains a separate concept from the temporary enhanced relief described in Ontario's 2026 Budget. The existing maximum is smaller, while the proposed temporary enhancement would increase provincial relief for eligible purchases.
Why the proposal is labelled verify-before-relying
The 2026 Budget describes proposed changes and says federal regulatory changes are needed for implementation. That is why the calculator labels the enhanced Ontario path as proposal-sensitive until final details are confirmed.
How this becomes a cash-to-close issue
Even when a buyer appears eligible, the cash outcome depends on whether the rebate is credited at closing or claimed later. A large rebate can still fail to solve a closing-funds shortfall if it arrives after closing.
Common mistakes
What buyers often miss
Reading headlines as final law
Government announcements and budget proposals are useful signals, but buyers should verify final implementation before relying on a closing number.
Missing construction deadlines
The proposed temporary Ontario path includes construction-start and substantial-completion timing, not only the agreement date.
Forgetting fallback rules
A purchase that does not fit the enhanced path may still have existing rebate treatment to consider.

What this page relies on
Ontario's 2026 Budget proposes a temporary enhancement to remove the full 8 percent provincial HST portion for eligible new homes valued up to $1 million, with an $80,000 provincial maximum maintained up to $1.5 million.
The same budget describes April 1, 2026 to March 31, 2027 as the proposed temporary window for enhanced Ontario rebates.
The budget states federal regulatory changes are required to implement changes to Ontario's existing rebates.
Frequently asked
Are Ontario's enhanced 2026 HST rebate rules final?
The app treats the enhanced Ontario path as proposal-sensitive until the launch source audit confirms the final enacted rules.
Can repeat buyers qualify for the temporary Ontario path?
The calculator models the announced temporary all-buyer/new-rental window separately from first-time-buyer paths and flags it for legal verification.
