Operation LENTUS is the Canadian Armed Forces (CAF) operational name for domestic disaster response missions within Canada. When natural disasters like wildfires, floods, or ice storms overwhelm provincial and municipal resources, provincial governments can request federal military assistance. CAF personnel deploy to evacuate residents, build flood barriers, assist firefighting operations, provide transportation, and support emergency services. LENTUS deployments have become increasingly frequent as climate change intensifies natural disasters. Municipalities benefit from military support during major emergencies while military assistance illustrates federal-provincial-municipal emergency management cooperation. Requesting LENTUS support involves formal provincial requests through Public Safety Canada.
