2025 Canadian wildfires

Wildfires are a natural part of the Canadian boreal forest life cycle. Climate change has led to higher temperatures and drier conditions, leading in turn to more frequent and severe fires and a longer fire season.{{cite journal | last1=Wang | first1=Weiwei | last2=Wang | first2=Xianli | last3=Flannigan | first3=Mike D. | last4=Guindon | first4=Luc | last5=Swystun | first5=Tom | last6=Castellanos-Acuna | first6=Dante | last7=Wu | first7=Wanli | last8=Wang | first8=Guangyu | title=Canadian forests are more conducive to high-severity fires in recent decades | journal=Science | volume=387 | issue=6729 | date=2025-01-03 | issn=0036-8075 | doi=10.1126/science.ado1006 | pages=91–97 | pmid=39745955 | bibcode=2025Sci...387...91W | url=https://www.science.org/doi/10.1126/science.ado1006 | access-date=2025-05-20}} The 2023 Canadian wildfires were the most destructive in recorded Canadian history and the 2024 wildfire season, while less severe, was one of the worst. Overwintering "zombie" fires continued to smoulder under snow in Alberta and British Columbia in January 2025, some of which began 2023.{{cite web | last=Carmichael | first=Jackie | title=Threat of 'zombie' Alberta, B.C. wildfires continue in 2025 | website=Edmonton Journal | date=2025-01-07 | url=https://edmontonjournal.com/news/local-news/alberta-b-c-winter-zombie-wildfires | access-date=2025-05-18}} Wildfire researcher Mike Flannigan stated that this is the first time he has observed such fires survive over two years.{{cite web | last=Hatch | first=Chris | title=A deadly start to wildfire season | website=Canada's National Observer | date=2025-05-16 | url=https://www.nationalobserver.com/2025/05/20/opinion/deadly-wildfire-season-manitoba | access-date=2025-05-20}} The British Columbia Wildfire Service had detected 49 active wildfires in early June that started as zombie fires, all near Fort Nelson.{{cite web | title=Canada hit by rise in 'zombie fires' that can survive the winter | website=Financial Times | date=2025-06-05 | url=https://www.ft.com/content/f87c4c4f-41de-4951-9bdf-286da55aac0f | access-date=2025-06-09}}

In Saskatchewan, rapid day-to-day shifts in temperature combined with low levels of snow created drought conditions; rather than seeping into the ground gradually and soaking the soil, snow would melt rapidly while the ground was still frozen and water would evaporate. Trees and grasses would rehydrate, grow, and dry out, leaving plentiful fuel. Boreal forests are more vulnerable to fire in the spring because deciduous tree have not yet grown their leaves, which store moisture.{{cite web | last=Hobson | first=Brittany | title=Claims Canadian wildfires are caused by arson and not climate change are misleading | website=thecanadianpressnews.ca | date=2025-06-11 | url=https://www.thecanadianpressnews.ca/fact_checking/claims-canadian-wildfires-are-caused-by-arson-and-not-climate-change-are-misleading/article_a87365f2-f35d-58b7-b082-fe6751d31f2f.html | access-date=2025-06-13}} With warmer weather happening earlier in the year, fires become more likely. Fires in the spring are more likely to be caused by humans, for example via abandoned campfires or hot machinery, while fires in the summer are more likely to have natural causes like lightning.

After the 2023 fires, Canadian governments began buying new water bombers, but they are not expected to arrive until 2029 at the earliest because of backlogs in orders.{{cite web | last=Bernstien | first=Jaela | title=Is Canada ready for a fiery future?

In Manitoba during mid-May, five fires were classified as "out of control". Fire conditions were exacerbated by a concurrent heat wave, with Winnipeg recording a temperature of {{Convert|37|C|F}} on May 13, breaking a temperature record that had stood for 125 years.

A wildfire located north of Whiteshell Provincial Park grew to over {{Convert|100,000|ha|acre}}. Dense smoke from the fire hampered aerial firefighting operations, forcing crews to focus on property protection in safer areas. A fire of {{Convert|42,000|ha|acre|abbr=unit}} in northwestern Manitoba had approximately forty firefighters from British Columbia assigned to it since May 13. A fire in Piney close to the Manitoba-United States border grew to {{Convert|7,000|ha|acre}}.

On May 13, a severe wildfire near the town of Lac du Bonnet, northeast of Winnipeg, resulted in two civilian fatalities. The victims, identified as a married man and woman, perished when they became trapped at home by rapidly advancing flames.

Wildfire smoke creates high levels of ozone and particulate matter such as PM{{sub|2.5}}, which can cause respiratory issues and increase the risk of cardiac arrest.{{cite web | last=Simon | first=Matt | title=The smoke from Canada's wildfires may be even more toxic than usual | website=Canada's National Observer | date=2025-06-09 | url=https://www.nationalobserver.com/2025/06/11/news/smoke-canadas-wildfires-may-be-even-more-toxic-usual | access-date=2025-06-13}} Many areas where wildfires have burned are home to former mining operations, which has left high concentrations of toxins such as arsenic, lead, and mercury that are then released into the air. Peat fires in particular can accumulate these toxins.

According to the Copernicus Atmosphere Monitoring Service, by June 2 the fires had emitted 56 megatonnes of carbon dioxide, second only to the 2023 season.{{cite web | last=Karnowski | first=Steve | title=Canadian wildfire smoke causes 'very unhealthy' conditions in American Midwest and reaches Europe | website=AP News | date=2025-06-03 | url=https://apnews.com/article/canadian-wildfires-smoke-air-pollution-minnesota-midwest-europe-24237c0043f70ed64db931cb2ce48b91 | access-date=2025-06-09}}
