First-time buyers of new homes priced up to $1 million can receive federal GST/HST rebates up to $50,000, with Ontario offering up to $80,000 in provincial relief, totaling up to $130,000. Eligibility depends on purchase dates and residency status. Rebates may be credited by builders or claimed later, affecting cash needed at closing. Lenders and insurers treat rebates differently, so buyers must confirm rebate timing and impact on financing to ensure smooth closings.
