The fires.

379 wildfires are burning in Canada right now. 246 of them are out of control. The national preparedness level is 1 of 5, and 4,474,173 hectares have burned this year — 44,742 square kilometres, more than an average recent whole year, with the season not over.

A word about the name. This site counts Parliament, and that is not changing. But it is called The Fire Computer, and in a country that now burns like this one does, a computer named fire that kept no watch on the actual fires would be a strange machine. This page is that watch, kept the way the rest of the record is kept: counted, sourced, corrected. It is not an emergency service — if a fire is near you, your province’s wildfire service is the page to have open, not this one.

Every fire burning right now

379 active wildfires as reported by provincial, territorial and federal agencies, on the map projection the federal government draws Canada with. Dot area follows reported fire size; the largest, 2026 ON THU FIRE 036 in Ontario, is 301,240 hectares.

out of control being held under control
A dot is a reported location, not a perimeter — a 301,240-hectare fire is not a circle and does not live at one point. Perimeter polygons exist (NRCan’s M3 layer) and are the obvious next step for this page. The 379 active fires sum to 2,783,584 hectares; the season total of 4,474,173 is larger because fires that are already out have left this map.

The season

Hectares burned in 2026, cumulative, week by week. The curve is the year happening: flat through winter, and then June.

The axis starts at zero. The dashed line is the 2015–2024 full-year average, 3,623,092 hectares — this year crossed it in early August.

The long record

The National Burned Area Composite measures every year since 1972 from satellite imagery rather than agency reports — slower, and consistent across five decades. The worst year in the record is not close: 2023, at 14,796,428 hectares.

The axis starts at zero. The lit bar at the right edge is 2026 to date — a partial year, drawn lit rather than left to pass as a finished one, and from a different instrument (agency reports, not the satellite composite). The season is not over.

The scars

The same record, drawn where it happened: every fire the satellite composite can outline, 1972 to 2025, on one map. Ink follows the decade — the palest marks are the 1970s, the brightest are now. Six seasons into the 2020s, this decade has burned 32,500,272 hectares; the 2010s, the worst complete decade in the record, needed ten to reach 25,225,187.

A pixel of this map is about 7.4 km of Canada. 42,046 fires too small to cover half of one are counted in every number on this page but not drawn — together 4,555,048 hectares, 3.4% of the record. The 10,564 fires drawn carry the other 96.6%. Where decades overlap the ink compounds: land that has burned more than once reads brighter, because it is.

An agency is who fights the fire, not quite a province: Parks Canada counts separately, inside whichever province the park is in. The Canada row is the sum of the rows above it, checked at build time against the same API’s own total.

The bill

Everything above this line updates by itself — satellites within days, agency counts within hours. What Canada spends on fire has no feed. Anywhere. These are the numbers that exist:

Fighting it: $800 million to $1.4 billion a year. That is Natural Resources Canada’s own range for what wildland fire management agencies spent annually over the last decade, topping $1 billion in six of those ten years, and rising by roughly $150 million per decade since 1970.
Recovering from it: heading to $1.8 billion a year. The Parliamentary Budget Officer projected in October 2025 that federal disaster assistance (the DFAA program, all hazards) will average $1.8 billion a year over 2025–2034, up from $881 million a year over 2010–2024 — with the wildfire share put at $325 million a year.
The table that isn’t there any more. The National Forestry Database published fire-management expenditure by agency and year — it is the series the academic literature on this question was built on. Its forest-fires section today lists fire counts, causes, months, size classes and property losses. The expenditure table is no longer among them. The hectares are measured by satellite within days; the bill is assembled by hand, years behind, and the one long public series of it has quietly stopped being offered. On a site about records, that is not a gap in this page. It is a finding.

Method

Live means fetched at build. Like /homes, this page cannot name one snapshot and stand behind it forever; it names the day it asked and exactly what it asked. Numbers on this page age until the next build. The active-fire layer updates intraday; a page built this morning is wrong by tonight, and says so here rather than pretending otherwise.

A fire is what an agency says it is. Counts and sizes are reported by the thirteen fire management agencies, not measured by this site. Reported size lags actual size, especially for fires being monitored rather than fought — which in a bad northern season is most of the burned area.

Two instruments, disclosed. The year-to-date figures are agency reports; the 1972–2025 chart is the satellite-derived National Burned Area Composite. They measure differently and disagree by design; this page never adds one to the other, and the one bar drawn from the wrong instrument is lit and labelled.

The map has no basemap tiles, no zoom, no third-party anything. Coastline is Natural Earth (public domain), projected at build time into the Lambert conformal conic the federal government maps Canada with, decimated to draw at this size. The page you are reading makes no request that leaves this site.

The scar map is the bar chart, drawn in place. The perimeters are the NBAC merged shapefile — 52,610 fire polygons, 1972–2025, published by the Canadian Forest Service in the same Lambert projection this page draws, so they pass through untransformed. A 1.26 GB shapefile becomes 380 kB of path by simplifying at 2 km and again at output resolution, and by not drawing fires smaller than half a pixel — counted and disclosed above, never silently dropped. The polygons’ per-year hectare sums reproduce the annual series to within two hectares, checked at every build: the chart and the map are one instrument twice, and cannot quietly disagree. 411 prescribed burns (177,285 hectares, 0.13% of the total) are in the composite, and therefore on the map.
