Canada is a big country, with a lot of forest and a lot of water. Fires are common, and are concentrated in the boreal forest region, a band of forest that stretches around the whole northern hemisphere. On average, out of around 400 million ha of forest, about 8,000 fires and 2.5 million ha burn per year. And dozens of communities and tens of thousands of people need to be evacuated each year.
People are mostly concentrated along the southern border with the United States, where it’s warmer. A lot of the northern communities are actually indigenous, and many of them are only accessible by air or water. If there is a road, it’s the only road. These communities are often threatened by wildfires, and are frequently evacuated due to this threat.
Ultimately, Canada has three main problems with respect to wildland fire - prevention, detection, and suppression. The Canadian Forest Fire Danger Rating System (CFFDRS) helps with each, though it’s only part of the solution. It helps with prevention by allowing fire managers to know where the risk of fires is higher. It helps with detection by giving fire managers a place and time to look for new fires. And it helps with suppression by providing some guidance about how the fire will behave. Beyond fire prevention, detection and suppression, CFFDRS helps with planning, response, risk assessment, smoke modelling, and even carbon emissions from these fires.
With respect to wildland fire, the Government of Canada has a mandate to provide for the safety and security of Canadians, to protect critical infrastructure, to mitigate the effects of climate change, and to aid the implementation of other Sustainable Development Goals like reducing poverty and improving health. All are aided by the CFFDRS.
