Federal support for natural disasters encompasses resources the federal government provides when emergencies exceed local and provincial capacity. Support includes: Canadian Armed Forces deployment for evacuations, sandbagging, and logistics during floods or fires; federal equipment and supplies including emergency stockpiles; financial assistance through Disaster Financial Assistance Arrangements (DFAA); specialized expertise and coordination; and emergency telecommunications and satellite resources. Provinces request federal assistance when disasters overwhelm their resources—the military doesn't deploy without a provincial request except for federal responsibilities. Federal support recognizes that major disasters can exceed any single province's capacity, and that national resources should be available to all Canadians facing emergencies. Climate change is increasing disaster frequency and severity, straining federal support programs and prompting discussions about sustainable funding levels and greater investment in disaster prevention.
