In 2023, more than 17.3 million hectares of land had burned in Canada because of forest fires. This was the largest annual land loss due to wildfires since records started. The number of forest fires in Canada stood at around 5,475 in 2023. The cost of Canadian wildfires In Canada, estimated property losses due to forest fires from 1970 to 2020 amounted to almost 250 million Canadian dollars. The province of British Columbia was by far the most affected, with losses of 115.4 million Canadian dollars, followed by Ontario with 57.9 million Canadian dollars.On the human side, the largest evacuation caused by wildfires in the North American country from 1980 to 2019 occurred in 2016, when more than 92,000 people were displaced. The Fort McMurray wildfire – the costliest natural catastrophe in Canadian history – took place that year. A worldwide picture Wildfires have been wreaking havoc around the world in recent years. In 2022 alone, around 5.2 million hectares of tree cover were lost due to wildfires. A year earlier, wildfire tree cover loss reached the peak of the century so far, with more than seven million hectares. In the past century, Russia has seen the largest annual tree cover loss due to wildfires, with an average of 2.5 million hectares. Canada is the second most impacted country in the world, with an average annual loss of roughly 1.3 million hectares during the same period.

Get data on forest fires, compiled annually for the National Forestry Database The National Forestry Database includes national forest data and forest management statistics to seve as a credible, accurate and reliable source of information on forest management and its impact on the forest resource. Forest fire data is grouped into eight categories, which are further broken down by geographic location. These include: * number of fires by cause class and response category * area burned by cause class and response category * number of fires by month and response category * area burned by month and response category * number of fires by fire size class and response category * area burned by fire size class and response category * area burned by productivity class, stocking class, maturity class and response category * other fire statistics, such as property losses

There were a total of 5,475 forest fires in Canada in 2023. As of November 2024, the total annual figure from the previous year almost gets surpassed at 5,374 fire stats in Canadian territory. Forest fires in Canada Forest fires in Canada have burned an average of 2.2 million hectares annually since 2000. Forest fires or wildfires are named so because they occur in areas such as woodlands, grasslands, and scrublands. They are not confined to remote forest areas and can cause extensive property damage and threaten the lives of people who live in transitional areas between regions of human habitation and wilderness. Since 2000, forest fires have caused an estimated 3.76 million Canadian dollars annually. A recent major forest fire which began in Fort McMurray, Alberta is likely to be the most economically damaging disaster in Canada’s history, according to insurers. The fires have also affected Alberta’s oil sands operations which have a significant impact on Canada’s GDP. What are the causes of forest fires? The Fort McMurray fire of 2016, like many forest fires, is suspected to have been caused by human activities. Fires started by humans can be intentional, as in the case of arson, or accidental, such as failing to fully extinguish a camp fire or cigarette. The most common natural cause of forest fires is human activity, which accounted for 2,719 fires in 2020.

Dataset including information on wildfires in the province of Alberta from 2006 to 2024, inclusive. Information tracked for each fire includes: cause, size, location (latitude and longitude, legal land description, and forest area), time and duration, weather conditions, staffing and physical resources used to suppress the fire, and area burned.

Forest fires are an important part of the Canadian landscape. The number of fires and area burned can vary dramatically from year to year, but there are more than 8000 reported wildfires in Canada during a typical year, burning an average of 2.5 million hectares or 25 000 square kilometres. Only 3 percent of fires in Canada reach a final size greater than 200 hectares, but these fires are responsible for 97 percent of the total area burned. This map shows the forest fire ignition causes for fires greater than 200 hectares. The data represent a compilation of all fire point location and perimeters for fires greater than 200 hectares, as provided by fire management agencies of provinces, territories and Parks Canada.

Wildfire Smoke Forecast in Canada This layer displays forecasted wildfire smoke across Canada sourced from BlueSky Canada's FireSmoke Canada app, updated every 6 hours. The wildfire smoke layer consists of hourly concentrations of particulate matter 2.5 microns and smaller (PM2.5) in units of micrograms per meter cubed (µg/m3) observed at ground level from wildfires. It is an approximation of when and where wildfire smoke events may occur over the next two days. This layer is sourced from BlueSky Canada's FireSmoke Canada app. Current Fire Danger Fire Danger is a relative index of how easy it is to ignite vegetation, how difficult a fire may be to control, and how much damage a fire may do. Fire Danger is a reclassification of the CFFDRS fire weather index (FWI) which is a numeric rating of fire intensity. These general fire descriptions apply to most coniferous forests. The national fire danger maps show conditions as classified by the provincial and territorial fire management agencies. Choice and interpretation of classes may vary between provinces. For fuel-specific fire behavior, consult the Fire Behavior Prediction maps.• Low: Fires likely to be self-extinguishing and new ignitions unlikely. Any existing fires limited to smoldering in deep, drier layers.• Moderate: Creeping or gentle surface fires. Fires easily contained by ground crews with pumps and hand tools.• High: Moderate to vigorous surface fire with intermittent crown involvement. Challenging for ground crews to handle; heavy equipment (bulldozers, tanker trucks, aircraft) often required to contain fire.• Very High: High-intensity fire with partial to full crown involvement. Head fire conditions beyond the ability of ground crews; air attack with retardant required to effectively attack fire's head.• Extreme: Fast-spreading, high-intensity crown fire. Very difficult to control. Suppression actions limited to flanks, with only indirect actions possible against the fire's head.Forecasted weather data provided by Environment Canada.

Forest fire danger is a general term used to express a variety of factors in the fire environment, such as ease of ignition and difficulty of control. Fire danger rating systems produce qualitative and/or numeric indices of fire potential, which are used as guides in a wide variety of fire management activities. The CFFDRS has been under development since 1968. Currently, two subsystems–the Canadian Forest Fire Weather Index (FWI) System and the Canadian Forest Fire Behavior Prediction (FBP) System–are being used extensively in Canada and internationally.Risque d'incendie actuel Le risque d'incendie est un indice relatif indiquant le niveau de facilité pour allumer un incendie de végétation, le niveau de difficulté qu'un incendie peut demander pour être contrôlé ainsi que la quantité de dommages qu'un incendie peut causer.Ces descriptions générales des incendies s'appliquent à la plupart des forêts de conifères. Les cartes nationales sur le danger d'incendie illustrent les conditions telles qu'elles sont classées par les agences provinciales et territoriales de gestion des feux. Le choix et l'interprétation des classes peuvent varier entre les provinces. En ce qui a trait au comportement des incendies en regard du combustible spécifique, veuillez consulter les cartes de prédiction du comportement des incendies.• Faible: Incendie possiblement auto-extincteur; de nouveaux allumages sont invraisemblables. Tout incendie existant est limité à couver dans des couches profondes plus sèches.• Modéré: Incendie de surface rampant modéré. Il est facilement circonscrit par les équipes au sol munies de pompes et d'outils manuels.• Élevé: Incendie de surface modéré à vigoureux avec implication intermittente des cimes. Pose des défis aux équipes chargées de le combattre sur le terrain; les équipements lourds (bouteurs, camions-citernes à eau et avions) sont souvent requis pour contenir l'incendie.• Très élevé: Incendie de forte intensité avec implication partielle ou complète des cimes. Les conditions au front de l'incendie sont au-delà de la capacité des équipes sur le terrain à y faire face; les attaques aériennes avec largage de produits ignifugeants sont requises pour combattre effectivement le front de l'incendie.• Extrême: Feu de cimes à forte intensité et à propagation rapide. Très difficile à contrôler. Les actions de suppression sont limitées aux flancs alors que seules des actions indirectes sont possibles au front de l'incendie.Prévisions météorologiques fournies par Environnement Canada.

British Columbia saw the largest number of forest fires in Canada in 2021. That year, there were more than 1,600 individual wildfires in the western province. Alberta followed as the province with the second most numerous wildfires.

In total, the number of forest fires in Canada was nearly 6,600 in 2021.

This dataset provides daily fire ignition locations and timing for boreal fires in Alaska, U.S., and Canada between 2001 and 2019. The fire ignition locations and timing are extracted from the ABoVE Fire Emission Database; however, the temperate prairies of Canada, the Atlantic Highlands, and Mixed Wood Plains were not included. Fires were detected from Landsat differenced normalized burn ratio (dNBR) and the daily MODIS burned area and active fire products. Detections by dNBR were limited to fire perimeters from national fire databases. Fire ignition locations were retrieved using a local minimum within the fire perimeters. However, when fire locations were confounded due to simultaneous active fire detections, the fire ignition location was set as the centroid of these pixels. A spatial uncertainty equaling the standard deviation of the pixels' coordinates and the nominal nadir of 1000 m was applied to the fire ignition location. The temporal resolution of the ignition timing is within one day. Data is provided in comma separated values (CSV) and shapefile formats.

Forest fires are an important part of the Canadian landscape. The number of fires and area burned can vary dramatically from year to year, but there are more than 8000 reported wildfires in Canada during a typical year, burning an average of 2.5 million hectares or 25 000 square kilometres. Only 3 percent of fires in Canada reach a final size greater than 200 hectares, but these fires are responsible for 97 percent of the total area burned. This map shows fires greater than 1000 hectares. The data represent a compilation of all fire point location and areas for fires greater than 1000 hectares, as provided by fire management agencies of provinces, territories and Parks Canada.

The current repository contains inputs, products and codes associated with the study by Rosu et al., "Large-scale impacts of the 2023 Canadian wildfires on the Northern Hemisphere atmosphere". This study investigates the short-term large-scale weather impacts of the 2023 Canadian wildfire emissions through the use the Earth System Model (ESM) EC-Earth3 [1]. It is noted that for this work, the EC-Earth3-AerChem configuration 2 was used. For the needs of this work, two sets of simulations took place, one while considering the fire emissions (NX) and one without (NC). Regarding the emissions used, the GFAS wildfire emission dataset was applied (refer to Kaiser et al. [3] and to [4]), while for the rest of the emissions, i.e. natural and anthropogenic, refer to van Noije et al. [2] and to [5]. The current repository contains the output derived from the aforementioned simulations, specifically black carbon AOD, cloud cover, organic AOD, total AOD, net downward radiation flux, secondary organic AOD, surface atmospheric pressure, atmospheric temperature, zonal wind, and meridional wind. Moreover, this repository also contains the MODIS AOD data [6] used in the study and the Python code used for post-processing the EC-Earth3 output. Finally, the AERONET V3 [7] and the MERRA-2 dataset [8] were also used in this work.

Wildland fire has a major impact on the sustainability of many Canadian forests. Fire policies attempt to balance suppression costs with values at risk while recognizing the natural role of fire in managing the landscape. There are three aspects of wildland fire in Canada: fire regimes, fire management, and fire research.

Get data on forest fires, compiled annually for the National Forestry Database The National Forestry Database includes national forest data and forest management statistics to seve as a credible, accurate and reliable source of information on forest management and its impact on the forest resource. Forest fire data is grouped into eight categories, which are further broken down by geographic location. These include: * number of fires by cause class and response category * area burned by cause class and response category * number of fires by month and response category * area burned by month and response category * number of fires by fire size class and response category * area burned by fire size class and response category * area burned by productivity class, stocking class, maturity class and response category * other fire statistics, such as property losses

This dataset provides vegetation community characteristics, soil moisture, and biophysical data collected in 2019 from 11 study areas, which contained 28 sites that were burned by wildfires in 2014 and 2015, and 14 unburned sites in the Northwest Territories (NWT), Canada. Burn sites included peatland and upland. These field data include vegetation inventories, ground cover, as well as diameter and height for trees and shrubs in the unburned sites. Similar data were collected for the unburned sites in the years 2015-18 and are available in related separate datasets. In 2019, the focus was on woody and non-woody seedling/sprouting regrowth data in the burned sites. Additional measurements collected at all sites included total peat depth, soil moisture, and active layer thickness (ALT). Soil moisture and ALT were collected for validation of the UAVSAR airborne collection and Radarsat-2 overpasses. This 2019 fieldwork completes five years of field sampling at the wildfire areas.
