Key figures
- About 4.48 million hectares burned in Canada by early September 2026
- More than 5,200 fires recorded this season
- 2023 and 2025 were Canada’s worst and second-worst fire seasons on record
- Ottawa is leasing 10 firefighting aircraft under a $316.7-million, five-year plan
In early June, Canada’s 2026 wildfire season looked mild. By June 10, about 1,750 fires had burned roughly 166,000 hectares — far less than at the same point in the record-breaking years of 2023 and 2025. Federal officials cautiously noted that the season was off to a slower start. They also warned that forecasts called for above-normal temperatures across nearly the entire country through the summer.
Then came July. Prolonged heat, low humidity and dry conditions turned northwestern Ontario and the Northwest Territories into tinderboxes. In just ten days in mid-July, more than 300 new fires ignited and the area burned nearly doubled. By mid-month, more than 900 fires were burning across the country, from British Columbia to Nova Scotia, and Canada raised its national preparedness level to the second-highest tier. By early September, according to the Canadian Wildland Fire Information System, about 5,300 fires had burned roughly 4.48 million hectares — an area larger than Switzerland — narrowly exceeding the ten-year average for that time of year.
A national emergency in remote places
The season forced the evacuation of thousands of people, including residents of numerous First Nations communities in northwestern Ontario, some of which are accessible only by air or winter road. One fire near Thunder Bay grew to more than 300,000 hectares, making it one of the largest in Ontario’s recorded history. In the Northwest Territories, fires burned well over a million hectares of boreal forest.
Smoke carried the crisis far beyond the fire zones. Plumes drifted across the Prairies, into Quebec and southern Ontario, and deep into the United States, triggering air quality warnings in cities hundreds or thousands of kilometres from the nearest flame. For many Canadians, the fires were not something they saw, but something they breathed.
The challenge: a changing fire regime
Wildfire is a natural part of Canada’s boreal forest, which has evolved with fire over thousands of years. What is changing is the frequency, size and intensity of fires. In August 2026, scientists at World Weather Attribution concluded that climate change has made extreme fire seasons in Canada a lasting reality rather than a rare exception.
The mechanisms are well understood. Warmer temperatures dry out trees, moss and soil more quickly, turning the forest floor into fuel. Snow melts earlier in spring, and autumn rains come later, so fire seasons start sooner and last longer. Warmer air also produces more thunderstorms, and lightning ignites the majority of the area burned in remote regions. Once fires grow large, they can create their own weather, generating winds and even thunderclouds that spread flames further.
Recent history shows how extreme things have become. The 2023 season burned about 15 million hectares — roughly six times the long-term annual average — including enormous fires in northern Quebec that sent smoke as far as Europe. The 2025 season ranked second-worst on record. The 2026 season, while less extreme, confirmed that even a slow start offers no guarantee.
The costs extend far beyond the flames. Homes, cottages, power lines, roads and railways are damaged or destroyed. Forestry companies lose timber, tourism operators lose summer revenue, and communities face months of disruption. Forests and peatlands release large amounts of stored carbon when they burn, adding to the very warming that fuels the fires. And the health effects of smoke are significant: fine particles from wildfire smoke can aggravate asthma and heart disease and are especially dangerous for children, older adults, pregnant people and anyone with existing health conditions.
What can be done
Canada is investing in response capacity. In 2026, the federal government committed $316.7 million over five years to the Canadian Interagency Forest Fire Centre to lease ten firefighting aircraft, creating a national aerial ‘surge capacity’ that can be deployed wherever the need is greatest. International firefighting crews from countries including Australia, Mexico, South Africa and the United States have also helped in recent seasons, and Canada sends its own crews abroad in return.
But experts across the country agree that suppression alone cannot keep up with a changing climate. The answer lies in reducing risk before fires start and preparing communities to withstand them.
FireSmart programs are a practical starting point. They help homeowners and municipalities clear dry vegetation and debris around buildings, use fire-resistant roofing and siding, keep gutters clean and create fuel breaks — strips of land with reduced vegetation — around towns. Most homes lost in wildfires are ignited not by the main fire front, but by embers blown ahead of it. Simple measures can make the difference between a house that survives and one that does not.
Indigenous fire stewardship is gaining overdue recognition. For generations, many First Nations used carefully timed, low-intensity burns to clear undergrowth, renew berry patches and grazing areas, and keep landscapes healthy. Colonial fire-suppression policies largely ended these practices, allowing fuel to build up. Reviving cultural and prescribed burning, led by Indigenous knowledge holders and supported by provincial agencies, can reduce the risk of catastrophic fires while restoring ecological and cultural values.
Detection and technology are improving quickly. Satellites, including new constellations designed specifically for wildfire monitoring, remote cameras and artificial-intelligence tools can spot fires within minutes of ignition, allowing crews to attack them while they are still small. Better fire behaviour forecasts help authorities decide when to issue evacuation orders.
Forest management also matters. Surrounding communities with more deciduous trees such as aspen and birch, which burn less readily than conifers, can slow the spread of flames. Planning where new homes and cottages are built — and avoiding high-risk areas — reduces future exposure.
Protecting public health is the final piece. Clean-air shelters, portable air cleaners in schools and long-term care homes, clear smoke alerts and guidance on using well-fitted masks all reduce the harm from smoke. Indoor air filters, including simple do-it-yourself box-fan filters, can significantly lower particle levels at home.
What you can do
Residents in forested areas can check their property against FireSmart guidelines, respect fire bans, prepare an emergency kit and evacuation plan, and sign up for local alerts. Everyone can prepare for smoke days by keeping an air cleaner or filter at home and checking air quality forecasts.
Canada cannot stop wildfires from happening — nor should it try to eliminate them entirely from forests that depend on fire. But with better prevention, Indigenous leadership, smarter technology and strong climate action, it can make them far less destructive.
