Question 1

Do I qualify for the Ontario HST housing rebate?

Accepted Answer

If you built a new home, did a substantial renovation, or added a major addition in Ontario, you likely qualify. Use the RebateMax calculator or book a free call and we'll confirm — no obligation.

Question 2

How much can I get back from the Ontario HST housing rebate?

Accepted Answer

Under the enhanced window, for agreements signed April 1, 2026 to March 31, 2027, eligible Ontario new homes and substantial renovations can receive up to $130,000. Outside that window, the legacy program applies: up to $24,000 for the Ontario portion on a new home, and up to $16,080 for an owner-built substantial renovation where no HST was paid on the land.

Question 3

Do I need to be a first-time buyer to qualify for the enhanced Ontario rebate?

Accepted Answer

No. The enhanced Ontario rebate for agreements signed April 1, 2026 to March 31, 2027 is open to all buyers, not only first-time buyers. A separate federal first-time buyers' rebate also exists, with its own rules.

Question 4

What does it cost to use RebateMax?

Accepted Answer

Nothing upfront. For enhanced-program claims the fee is a flat $3,500 plus HST, charged only on a successful claim. For legacy claims the fee is 15% of the rebated amount plus HST, capped at $3,500.

Question 5

Does my renovation qualify as a substantial renovation?

Accepted Answer

A renovation generally qualifies as a substantial renovation when 90% or more of the interior of the existing house is removed or replaced, counting only livable areas. A major addition that at least doubles the livable area, combined with significant changes to the existing house, can also qualify. RebateMax assesses eligibility free of charge.

Question 6

Does a garden suite or ADU qualify for an HST rebate?

Accepted Answer

A garden suite or accessory dwelling unit can qualify as its own claim when it is a separate building used as a primary residence, subject to the program rules. RebateMax reviews the specific project to confirm.

Question 7

How long does an HST rebate file take?

Accepted Answer

Most files are prepared in 1–2 weeks once we have your documents; CRA processing times vary.

Question 8

What if CRA audits my HST rebate claim?

Accepted Answer

Every RebateMax file includes full audit support. We handle CRA correspondence start to finish.
