Property Owners are required to fill a “Records of Site Condition (RSC)” with the Environmental Site Registry. The record of site condition (RSC) sets out the environmental condition of a property at a particular point in time, based on environmental site assessments conducted by a qualified person.

The Records of Site Condition is typically required if the use of the property is being changed to a new and more sensitive use than the previous. These properties may also include vacant or abandoned properties that were used in the past for commercial or industrial activities, such as factories, gasoline service stations and waterfront properties, also known as Brownfield properties.
