Housing starts in Ontario have sharply declined, with condo starts down 52% and ground-oriented housing down 43% compared to recent averages. The core issue is that builders cannot produce homes at affordable prices due to high development charges, slow approval timelines, and tax burdens like HST. Solutions include reforming infrastructure funding, speeding approvals, making HST relief permanent, scaling industrialized construction, and updating building codes to allow more flexible mid-rise housing designs.
