The service delivery model (SDM) is intended to support First Nations communities in their crisis planning, prevention, response, and recovery. The SDM is to be used by the communities as a reference document to support their own process of planning and development, not to be adopted as written. First Nations communities may have their own unique definition of crisis and capacity to plan, prevent, respond to, or recover from incidents or events. The intention reflected in this SDM is that the unique characteristics and priorities of each community are respected.
