Operation LENTUS

CAF response to forest fires, floods, and natural disasters in Canada

Operation LENTUS is the Canadian Armed Forces (CAF) response to natural disasters in Canada.

Provincial and territorial authorities are the first to respond when a major natural disaster occurs in Canada. If they become overwhelmed, they may ask the CAF for help.  When the CAF responds to such a crisis, it is known as Operation LENTUS.

Operation LENTUS follows an established plan of action to support communities in crisis. This plan can be adapted to multiple situations. These might take the form of forest fires, floods, ice storms, or hurricanes.

The objectives of Op LENTUS are:

  • to help provincial and territorial authorities
  • to respond quickly and effectively to the crisis
  • to stabilize the natural disaster situation

Attention: Update on CAF assistance to British Columbia firefighting efforts

On July 9, 2017, the Province of British Columbia (BC) asked the Government of Canada to help its emergency response to wildfires. Later that day, the CAF began sending personnel and aircraft to BC.


The CAF is conducting the following tasks in support of BC:

  • Supporting provincial firefighters in firefighting operations
  • Evacuating locals who are affected by the wildfires
  • Transporting first responders and equipment
  • Delivering essential aid to isolated communities

The following CAF aircraft are currently deployed:

  • Two CC-130J Hercules
  • Two CH-147F Chinook helicopters
  • Three CH-146 Griffon helicopters


A CC-177 Globemaster III was also deployed on this operation. Additional aircraft are available to be tasked if the Province of BC needs more help.



  • July 9, 2017: The Province of BC requested Government of Canada assistance. The  CAF had already sent liaison personnel, started planning, and pre-positioned aircraft so they could respond quickly when the Province of BC requested help.

Under operational control of the Commander of Joint Task Force Pacific, these members are assisting the RCMP in providing information to the public, and in conducting observation and reporting tasks at assigned points along access roads in affected areas. They will also assist with the ground evacuation of persons in distress and the ground delivery of essential aid to affected areas.
