Ontario's residential construction sector shows resilience due to strong demand for new single-family homes, supported by tax incentives that reduce or eliminate HST on new builds up to $1.5 million, offering savings up to $130,000. This offsets rising costs from trade tariffs on materials. GTA single-family home sales in August rose 47% above the decade average, with prices down 14.6% annually before rebates. Multi-family high-rise sales lag due to tax incentive timing rules. The sector supports 256,000 jobs and $39.3 billion in investment, aiding economic stability amid trade disruptions.
