Deaths linked to wildfire smoke in Canada have exploded by about 275 per cent since the early 2000s according to a major global report that tracks connections between health and climate change. The report, published Tuesday in The Lancet, found that an average of approximately 4,000 deaths were associated with wildfire smoke in Canada each year between 2021-25. That’s compared with an average of only 1,050 annually in 2003-12. …Ian Hamilton, the chair in planetary health at the George Institute for Global Health at Imperial College in London, co-authored the study, says the year range used for wildfire smoke-associated deaths, 2003-12, is meant to represent a historical baseline. According to the report, Canada lost approximately 5.2 million hectares of tree cover in 2024, 148 per cent more than in 2016 — and wildfires accounted for 86 per cent of the loss. …The report also says 80 per cent of Canada’s heatwave days in 2025 were directly attributable to fossil fuel-driven climate change.
We can’t do much to prevent losing more communities to wildfires, and we certainly can’t reduce the scale of fires in the boreal forest. But we can minimize the health impacts of wildfire smoke, which should help us deal with the economic impact of wildfires and other climate disasters. …First, we need to minimize the damage of PM2.5 and other particles in wildfire smoke. That would involve more airtight homes, workspaces and schools, plus air purifiers in every room and office. In new construction, air purification should be built right into the heating, ventilation and air-conditioning systems. Second, we need to start using N95 masks whenever air quality drops. …Third, we need to recognize that wildfires and heat waves can threaten electricity grids by damaging transmission lines. The remedy here would be installing enough solar power in homes and workplaces. …We will also have to prepare for long-term health consequences of wildfires.
The perils of wildfire smoke don’t stop at the lungs or the heart. They can also affect the brain. Recent research shows tiny particles from wildfire smoke — known as PM2.5, fine particulate matter — are so small they can travel deep into the lungs. But they don’t always end their journey there. Some slip into the bloodstream, or get to the brain directly through the nose, says Dr. Bhavini Gohel of the University of Calgary’s O’Brien Institute for Public Health. When toxins reach the brain, they can cause inflammation, resulting in fogginess, lack of focus and headache, she says. Increasing exposure to these harmful particles can also cause long-term damage to brain cells leading to cognitive decline. …The Climate Health System Alliance, says an increasing exposure to this air can lead to dementia. …A study found people living in areas with higher air pollution scored worse on memory tests.
Thick, choking plumes of smoke from Canadian wildfires are pouring into major cities across the Great Lakes, Northeast and Mid-Atlantic, bringing dangerous air quality to more than 100 million people. The polluted air will last through at least Saturday in some areas as new waves of smoke waft south. …More than 100 million people in 18 states are under air quality alerts, many of which note that the air pollution is so high, even healthy adults will be affected. “The risk of health effects is increased for everyone,” the DC, air quality council said. …The smoke is being carried south from Canada in the wind. On Friday, the plume pushed farther south, making the DC area the new East Coast-epicenter of air pollution. Relief is coming as the wind pushes the smoke back into the Northeast and rain and storms are in the forecast
It’s a big win for Yukon’s wildland firefighters. The Yukon government tabled a bill on Tuesday that would amend the territory’s Workers’ Safety and Compensation Act to include wildland firefighters under presumptive cancer coverage. Currently, only full-time and part-time structural firefighters are covered under the act for 19 types of cancer. Wildland firefighters are not included. Laura Lang, Yukon’s minister responsible for the Workers’ Safety and Compensation Board, said wildland firefighters are there to support and protect communities in times of need, so it’s time to reciprocate that support. “Under the proposed change, when a wildland forest fighter is diagnosed with a listed cancer and meets the legislated eligibility requirements, their cancer would be presumed to be work-related,” she said. “For those who qualify, that means less red tape and a lot more straightforward, predictable claims processes.”
Two B.C. companies are receiving provincial support to deploy clean-energy technology that strengthens backup power reliability for general aviation aircraft in B.C., replacing diesel generators with battery storage to keep critical services, such as wildfire response, medical transport and search and rescue, running during emergencies. With as much as $1 million being provided through B.C.’s Integrated Marketplace, Abbotsford-based Fast Air will deploy a mobile battery and solar power system developed by Richmond-based Holinova at the Abbotsford International Airport. …The Fast Air-Holinova project is the second project launched under Integrated Marketplace’s Forestry Innovation and Emergency Management Testbed. Announced in December 2025, the Forestry Innovation and Emergency Management Testbed enables testing of technologies that may generate insights and data that could be implemented throughout the province. The data could provide insights to help: improve emergency response; improve resilience; streamline emergency processes; and build efficiencies in the forestry sector.
A man has died following a workplace incident at a forestry business in Golden last week. Golden-Field RCMP responded to the scene at about 9:51 a.m. on Aug. 17, after reports of a serious workplace incident. Police said the initial investigation indicates the man was working alone on a logging truck when the vehicle moved and injured him. RCMP and B.C. Emergency Health Services attended, but the man was pronounced dead despite the efforts of first responders. The B.C. Coroners Service is conducting an independent investigation, and WorkSafeBC has also been notified and will investigate the circumstances surrounding the workplace death. An RCMP collision reconstructionist examined the scene, while Commercial Vehicle Safety and Enforcement inspected the logging truck and found it to be in excellent mechanical condition.
Three BC ministries — Health, Emergency Management and Climate Readiness, and Forests — provided an update on on wildfire and smoke conditions in British Columbia. This is the first wildfire season update that has included Provincial Health Officer Dr Bonnie Henry. … Effects of wildfire smoke can be felt even at a distance from the fires, said Dr Bonnie Henry in her opening remarks. Children are more affected because their lung are small relative to their body weight. Smoky air can result in throat irritation, headaches, cough and runny eyes which Dr Henry called “short term effects”. But she says she has “concerns” about long term effects, including how very small PM2.5 particles of from smoke and soot get deep into the lungs and infiltrate to other parts of the body. …She highlighted an announcement that N95 masks are being provided free in BC wildfire zones, through the Canadian Red Cross with federal funding.
When people see or hear that a fire has started beside a highway or road, many probably think that a casually discarded cigarette butt tossed out a window is the culprit. Not so, says Ashcroft Fire Rescue Chief Josh White. …he says that most roadside fires could be prevented if drivers took a few simple steps to make their vehicles more roadworthy… According to the BC Wildfire Service, only 0.8 per cent of human-caused fires in B.C. each year are caused by discarded smoking materials. By contrast, vehicles are responsible for 3.8 per cent of human-caused fires each year. …White says that there are three main things people can do to reduce the risk of vehicle fires. “Get the vehicle serviced regularly; don’t overload the vehicle; and carry a working fire extinguisher. It won’t necessarily put a fire completely out, but it’s good at knocking down a small fire”
THUNDER BAY, Ontaro — Former workers of Dryden’s Weyerhaeuser Pulp and Paper Mill who were exposed to toxic fumes in the early 2000s gathered Thursday to provide updates on the lifelong impacts it has had on their health. The Occupational Health Clinics for Ontario Workers (OHCOW) invited the former employees to the Thunder Bay OPSEU offices to conduct updated interviews on their health and employment history, to be used in WSIB claims. In total, about 400 workers were exposed to fumes between 2002 and 2004, during the construction of the mill’s recovery boiler #4, said OHCOW’s executive director for projects, Andrew Zarnke. By midday Thursday, 35 of those workers had come to be interviewed. …Many records, according to OHCOW, state that there were no controls, forced ventilation, extraction or plume-control systems. Further records state that emissions were blown into the construction site that was covered with unsealed tarp and siding.
Dangerous heat is gripping parts of the United States, with more than 39 million people under heat alerts across much of the South as temperatures are expected to rise over the weekend. Temperatures in some cities have climbed above 100°F. …The “heat dome” that brought extreme heat to much of the central and eastern U.S. has shifted west and is expected to intensify before expanding into the intermountain West and northern High Plains this weekend. Parts of the Southwest are forecast to reach 110-120°F from late this week into early next week, with some locations expected to experience one of their 10 hottest days on record. Extreme heat warnings are in effect on Friday across parts of six states: Arizona, California, Nevada, Utah, Oklahoma and western Arkansas. …Such levels are “dangerous for anyone without adequate cooling or hydration,” the weather service warned.
AUGUSTA, Maine — The Maine Department of Labor has cited six fire departments for lacking an effective system to track firefighters at the scene of the deadly May fire and explosion at Robbins Lumber in Searsmont. The department also cited four of those fire departments, Searsmont, Morrill, Montville, and Belmont, as well as Searsmont Rescue over personal protective equipment protocols. Morrill was cited for 11 items in all. The findings follow workplace safety investigations involving the Searsmont, Morrill, Montville, Belmont, Appleton and Lincolnville fire departments, as well as Searsmont Rescue. …The labor department is suspending nearly all of the $108,000 in penalties it issued. Montville must pay $1,000 because of a record of one repeat fit-testing violation. “We believe that it is more important for these towns and departments to allocate their resources toward the improvement efforts than it is to pay a civil penalty,” Burkhart said.
SEARSMONT, Maine — Two volunteer firefighters died and 11 others were injured after an oxygen-limiting silo exploded during a fire at a Maine lumber mill. The 20-by-60-foot silo contained kiln-dried wood shavings and residual sawdust. Neither facility employees nor responding firefighters recognized that the silo was oxygen-limiting or that its contents posed a combustible dust explosion hazard. Crews directed water through an opening into the silo’s base for more than 30 minutes. At approximately 11 a.m., firefighters heard a “whoosh” as smoke rapidly vented from the top, and the silo launched into the air as fire erupted below it. NIOSH’s investigation highlights the need for hazard-specific preplans, disciplined accountability and tactics designed for oxygen-limiting silos. Recommendations for fire departments include:
AUCKLAND, New Zealand — A coroner is calling on Worksafe to look at strengthening safety regulations in the forestry sector, after a 39-year-old father of two was crushed to death by a falling tree. Mykhailo Tremel was working on a forestry block in Clevedon, south of Auckland, in June 2022. …Worksafe prosecuted Turoa Logging Limited – who had hired Tremmel – and Pulley Contracting Limited – who was managing the harvesting. After pleading guilty in the Manukau District Court, they were fined and ordered to pay reparations totalling more than $300,000. …In her finding, released to the public on Monday, coroner Rachael Schmidt-McCleave said said, had a logging machine been used, Tremel’s death would likely have been prevented. “I further find that better observation techniques, call-in procedures and emergency response procedures would have (on the balance of probabilities) improved the chances of Mr Tremel having a favourable outcome after the accident.”
