Click to view Metadata In November 2025 updated natural hazards regulation mapping was endorsed by the CLOCA Board of Directors following a period of public notification. Mapping of areas that could be unsafe for people and property in the event of a flooding or erosion emergency across the watershed is a mandatory service that CLOCA provides in accordance with provincial regulations. The mapping conceptually shows areas associated within hazardous lands including valleylands, wetlands, watercourses, and other areas that could be subject to flooding and erosion hazards, including the Lake Ontario Shoreline. The mapping is based on provincial statutory requirements and technical information such as flood and erosion studies prepared by professional engineers and geographic information associated with wetlands, watercourses and topography prepared by other environmental specialists.
