Ontario's plan to build 1.5 million homes by 2031 is falling behind, with only 260,000 built so far and projections showing slow construction through 2027. To meet the target, housing starts must more than double in the final five years. The 2025 budget adds funding for infrastructure and modular housing but keeps existing incentives unchanged. Critics call the measures ineffective, while the government remains committed despite challenges like tariffs and municipal shortfalls.
