An Ontario new housing rebate may be available even if the total price or fair market value of the house is above the applicable threshold.

You are eligible to claim the Ontario new housing rebate if you bought a new or substantially renovated house (including a new condominium unit, mobile home or floating home) from a builder or you bought a share of capital stock of a co-op, the house is located in Ontario and is for use as your or your relation's primary place of residence, and either:

1. you are eligible to claim a GST/HST new housing rebate for some of the federal part of the HST
2. the only reason you are not eligible to claim a GST/HST new housing rebate for some of the federal part of the HST is because the total price or fair market value of the house exceeds the applicable threshold

The maximum Ontario new housing rebate amount that is available is $24,000.
