Ontario's Places to Grow Act is provincial legislation establishing the Growth Plan for the Greater Golden Horseshoe, directing where and how urban development should occur in Ontario's most rapidly growing region. The Act requires municipalities to plan for specified population and employment growth, intensification targets, and density minimums around transit stations. It aims to reduce sprawl, protect farmland, and create complete communities with housing, jobs, and services. Municipal official plans must conform to provincial growth plans. The legislation demonstrates provincial authority over municipal land use planning, sometimes creating tension when provincial targets conflict with local preferences.
