Developer charges (also called development levies or development cost charges depending on the province) are fees municipalities collect from developers to fund infrastructure required to service new growth. The principle is that growth should pay for growth—new development creates demand for roads, water and sewer systems, parks, recreation facilities, and other services that existing taxpayers shouldn't have to fully subsidize. These charges are calculated based on the anticipated infrastructure costs attributable to development, divided among expected units. Typical charges range from thousands to tens of thousands of dollars per housing unit. Revenue must generally be used for growth-related capital projects rather than general municipal purposes. Provincial legislation governs how charges are calculated, what costs can be recovered, and how funds must be managed. Developers ultimately pass these costs to homebuyers.
