The Canadian Armed Forces and Natural Disasters

Background

A natural disaster is an event caused by natural forces that results in serious damage to human life, property and/or the environment. In such cases, the affected community often requires outside assistance. Natural disasters can take many forms. In Canada, the most common are wildfires, floods, storms, extreme temperature events, earthquakes, avalanches and landslides. Canada rarely experiences tsunamis, while volcanic eruptions are unknown.

If local authorities are unable to respond adequately to a natural disaster, they can ask their provincial or territorial government for help. In turn, provinces and territories may ask the CAF for help if the emergency escalates beyond their capabilities.

CAF Assistance to 2013

The CAF has assisted communities with natural disasters, particularly floods, storms and wildfires, since at least 1950.

Floods

Approximately 5,000 service personnel responded to the Red River Flood of 1950, which saw 100,000 residents (one third of Winnipeg) evacuated, 10,000 homes destroyed and 5,000 buildings damaged. During Operation Saguenay, the CAF response to the Saguenay River Floods of 1996, CAF personnel provided air evacuation and emergency accommodation, while the Red River Floods of 1997 saw more than 8,500 personnel deployed on Operation Assistance. In 2011, flooding along Manitoba’s Assiniboine River resulted in more than 1,800 personnel deployed for Operation Lustre, along with seven helicopters and a patrol aircraft.

Storms

Hurricane Hazel, which hit Toronto in 1954, resulted in more than 800 army reservists called out to aid the stricken city. The Great Ice Storm of early 1998 struck parts of eastern Ontario, southern Quebec and New Brunswick, leaving four million people without electricity. Operation Recuperation saw almost 16,000 CAF personnel deployed to provide humanitarian assistance and help with power restoration.

Another weather-related disaster was Hurricane Juan, which hit parts of Nova Scotia and Prince Edward Island in 2003 and saw some 2,000 military personnel deployed. In 2010, Hurricane Igor, the most powerful storm ever recorded in the Atlantic Basin, hit Newfoundland and Labrador. Operation Lama, the codename for CAF support following the hurricane, resulted in the deployment of more than 1,000 personnel, as well as three ships, three helicopters and a transport aircraft.

Wildfires

In 2003, about 2,700 CAF personnel, supported by four helicopters, fought massive forest fires in British Columbia in Operation Peregrine.

Operation Lentus (2013–present)

Since 2013, the CAF response to natural disasters has been known as Operation Lentus. The demand for CAF personnel and resources during natural disasters has increased substantially in recent years, and all provinces and territories have received assistance. The table below summarizes this response to 2026.

Disaster Prevention: the CAF and Avalanche Control

The CAF also plays a key role in preventing natural disaster. The 18 km section of the Trans-Canada Highway through Rogers Pass in British Columbia’s Glacier National Park has the highest avalanche rating of any highway in North America.

To counter this threat, Parks Canada operates the largest mobile avalanche control program in the world. Since 1961, Operation Palaci has deployed artillery soldiers every year to Rogers Pass, where they fire 105mm howitzer shells into known avalanche zones to trigger an avalanche. The section of road is then temporarily closed, allowing ploughs to safely remove the snow and keep the highway open.

Competing Demands: CAF Role in the Future

In June 2024, Chief of the Defence Staff General Wayne Eyre stated he was concerned about the CAF’s overall readiness to respond to events in Canada and abroad as it deals with increasing demands to assist with natural disaster response at home. Although the CAF will continue to support civil authorities to respond to natural disasters, that is not its primary role. Provinces and territories must provide first responders and only request CAF support when the situation exceeds their capabilities and no other organizations are able to assist.
