Where this data comes from

Perimeters are official, from the NBAC of Canada’s CWFIS (Natural Resources Canada, Open Government Licence – Canada); for the current season they are rebuilt from heat detections by GWIS (Copernicus, CC BY 4.0) until NBAC publishes the year. Census subdivision boundaries come from geoBoundaries/Statistics Canada (StatCan) (Open Data Commons Open Database License 1.0). The area per census subdivision is computed by WorldFires by crossing both. The forecast is from Open-Meteo (CC BY 4.0).
