Mapping Natural Hazard Exposure
These are three separate public layers, not one model. NRCan Earthquakes Canada supplies PGA for NBC design values (commonly 2% in 50 years). CWFIS publishes fire weather and hotspots. Flood-plain maps stay with provinces and municipalities, with federal support through the Flood Hazard Identification and Mapping Program.
Flood risk
Provincial and municipal flood-plain maps remain the local authority; federal FHIMP supports updated hazard identification.
