Research Supports Ontario Housing Tax Holiday

New research supports the case for a three-year Harmonized Sales Tax (HST) holiday on new home sales in Ontario. Proponents argue that tax relief on new construction is necessary to address the region's housing crisis. The proposal aims to incentivize development and increase housing supply.

- The proposed tax relief is part of a dual-government effort; the Ontario government has proposed rebating its full 8% provincial portion of the HST on new homes for first-time buyers up to $1 million. This is intended to align with a federal proposal to remove its 5% portion (the GST). - If both the provincial and federal proposals are enacted, a first-time homebuyer could save up to $130,000 on a $1 million home, with partial rebates available for homes valued between $1 million and $1.5 million. - The proposal comes as Ontario's housing starts are projected to fall to near two-decade lows in 2026, driven by a sharp decline in condominium pre-construction sales. Annualized housing starts are currently tracking at under 54,000, which is just 30% of the province's target of 175,000 new units per year. - Construction of family-oriented housing has been hit particularly hard, with starts for single-detached, semi-detached, and row houses hitting a record-low in January 2026. - Proponents like the Residential Construction Council of Ontario (RESCON) argue that taxes, fees, and levies account for nearly 36% of the cost of a new home in the province, a figure that has increased from 31% in 2021. - The federal legislation related to the GST rebate, Bill C-4, was passed by the House of Commons in December 2025 but still requires Senate approval as of February 2026. Ontario's parallel rebate is contingent on this federal bill passing. - Some industry groups, including RESCON, are advocating for the HST rebate to be expanded to all new home purchasers, not just first-time buyers, to have a broader impact on stimulating housing construction. - The Canada Mortgage and Housing Corporation (CMHC) forecasts that new home construction will continue to decline through 2028 due to high costs, weaker demand, and a rising inventory of unsold units.
