*The referenced federal and Ontario temporary enhanced GST/HST new housing rebate measures are proposed and not yet in effect. Their availability depends on enactment of the necessary legislation by the Government of Canada and/or the Government of Ontario (including receiving Royal Assent). The Ironstone Building Company has no control over whether these measures are enacted.

The availability, eligibility criteria, rebate amounts, application forms, and timing will be determined by legislation and by administrative guidance issued by the applicable authorities. The Ironstone Building Company does not control whether, when, or in what form any such measures take effect. Application procedures (including any assignment of rebates, if permitted by law) and processing times are set by the applicable authorities, not by The Ironstone Building Company.

Home prices listed on ‘The Ironstone Building Company’ website are inclusive of applicable GST/HST, net of the existing GST/HST new housing rebate (current maximum rebate of $24,000 in Ontario), but does not include the newly enacted first-time home buyer GST/HST rebate(s) or the newly proposed temporary enhanced Ontario GST/HST new housing rebate. As such, this calculator only estimates the newly proposed temporary enhanced Ontario GST/HST new housing rebate, and does not include the existing GST/HST new housing rebate(s) or the first-time home buyer GST/HST rebate(s).

Any price or incentive that references or assumes a GST/HST rebate (including any “net of rebate” pricing) is conditional on the applicable legislation being enacted as anticipated and on the purchaser’s eligibility. If the legislation is not enacted, is enacted with different terms or timing, or the purchaser is ineligible, any assumed rebate will not apply, and the purchaser may be responsible for the full purchase price without the benefit of any such rebate.

This material is provided for general information only, does not consider your specific circumstances, and does not constitute tax or legal advice. Purchasers should consult their own tax and legal advisors.

References to an Ontario rebate relate to the provincial component of HST for homes in Ontario only. Other provinces and territories may have different rules.
