Development charges

Development Charges (DCs) are one-time fees levied by municipalities on new residential and non-residential lands. The purpose of DCs is to ensure that new development pays for the infrastructure growth (such as road improvements, new facilities and other infrastructure) that is required to meet the needs of the growing community. These charges apply to all County services on a countywide basis with the exception of Community Housing as well as Waste Diversion – Curbside Collection, which applies in the benefitting service area only (outside of Port Hope Rural Ward II).
