The Ontario government announced measures to address challenges in the overheating housing market, including initiatives to cool demand, boost supply, and expand rent control. Demand cooling measures include a 15% tax on non-resident home buyers and preventing pre-construction property flipping. Supply boosting measures aim to increase development through incentives for purpose-built rentals and leveraging provincial assets. Expanded rent control applies to all renters, including units built after 1991, but may have unintended consequences of reducing rental supply if it discourages investment.
