New home sales in Ontario surged 130% year-over-year in Q2 2026, reaching 8,410 sales, driven by an enhanced HST rebate offering up to $130,000 to buyers. This boost helped protect 17,300 construction jobs, preserve $2.8 billion in GDP, and maintain $1.4 billion in government revenues. Most sales were single-family homes, while condo sales remained below the 10-year average. Further economic gains are expected from upcoming cost reductions for builders.
