Background Information
Ontario's Emergency Management and Civil Protection Act (2003) requires all municipalities and provincial ministries to implement risk-based emergency management programs in accordance with the Act and its associated standards.
The foundation of municipal and ministry emergency management programs is a hazard identification and risk assessment (HIRA) process. The HIRA serves as the basis for emergency management program decision-making and prioritization.
This website presents material and map data for atmospheric and climatological hazards in Ontario. Its purpose is to assist municipalities and ministries in identifying specific atmospheric and climatological hazards that may affect them and to provide data that will assist in assessing the probability of occurrence for each identified hazard.
This website does not, at this time, contain information to specifically assist with the determination of consequences related to atmospheric and climatological hazards. An assessment of consequence (severity), as well as probability of occurrence, is vital to conducting a risk assessment for identified hazards. The Faculty of Environmental Studies at York University, in cooperation with Environment Canada and Emergency Management Ontario (Government of Ontario), is currently conducting pilot programs in two Ontario municipalities to evaluate methods for assessing consequence related to atmospheric and climatological hazards.
