Montréal and Toronto have some of the worst air quality in the world due to wildfire smoke: How to protect yourself, according to an expert
Toronto and Montreal's air quality is on par with some of the worst in the world due to drifting wildfire smoke. While fires continue to burn in Western Canada, wind has carried smoke from the fires to Ontario, Quebec and areas in the U.S. like Nebraska, Michigan and Wisconsin. The impact of wildfire smoke is so severe, Environment Canada issued air quality statements for the Greater Toronto Area (GTA) and Montréal Island Area. As of 12:25 p.m. EST., IQAir, a Swiss technology company, ranked Montreal as the city with the worst air quality in the world. Toronto came in third place, behind Santiago. Environment Canada is encouraging people, especially the elderly, pregnant people, children and people with chronic health conditions, to avoid spending time outdoors whenever possible. As of June 6, the Canadian Interagency Forest Fire Centre reported 212 active fires in Canada, with 91 considered out of control. Mandatory evacuation orders were issued for parts of Alberta and Saskatchewan due to poor visibility and air quality due to smoke. Manitoba's state of emergency required residents of several communities to evacuate due to air quality and lack of power.

Contact a qualified medical professional before engaging in any physical activity, or making any changes to your diet, medication or lifestyle. Wildfire smoke isn't just contained to affected areas. Environment Canada has issued a weather alert for parts of Ontario due to poor air quality that may cause people to experience symptoms like cough, headaches as well as nose and throat irritation. The Weather Channel in the U.S. reported wildfire smoke from Canada is visible as far as the Gulf Coast. Winds have caused smoke to impact air quality in states like Minnesota, Iowa, Wisconsin, Michigan as well as North and South Dakota. As the wildfire season kicks off, ways to protect ourselves from smoke are top-of-mind for many. Yahoo Canada previously spoke to a top respirologist in Toronto, who weighed in on the impact of smoke on our lungs, and what to do to stay safe. Read on for everything you need to know. Dr. John Granton, a respirologist at the Toronto General Hospital (University Health Network), told Yahoo Canada wildfires cause air pollution that can have a far-reaching effect on human health. Small air pollutant particles in the smoke, called the PM2.5 particles, are "where a lot of the toxic stuff lives," Granton explained. "That's not filtered by your upper airway, that gets access to your lower airway and into your bloodstream even — and that's where the danger lies. "That can cause asthma attacks, can cause heart attacks, can contribute to hospitalizations and has long-term health outcomes." Even just the smell could cause problems to some, he said. "Being in smog all day long, the smell bothers people; it can cause irritation of the upper airway, some of the larger particles can cause irritation, and cause symptoms. People [who] have chest symptoms or asthma, it can make them feel worse." Granton said smoke isn't easy to escape, but there are some things people can do try and stay safe. According to Granton, "there's not a lot of data to support the health benefits of masking" when it comes to safety from wildfire smoke. But, he said there is research looking into the effectiveness of filters. "Cloth masks or scarves and things are not effective at all," the doctor claimed. But, surgical masks and N95 filter masks "tend to filter those smaller particles," he added, "apparently some of those masks are effective." Granton said "they're not going to filter the gases," though, and there are studies that question whether masks that aren't properly fitted would actually help in the real world. "Whether or not that has a direct health benefit is speculative right now," Granton explained. However, he said it "may be reasonable" for those who have underlying health conditions and those who have to be in the hotspots of the pollution to wear one. "If you have to be outdoors and doing things, then wearing that sort of mask to protect you would be sensible." Though filtration masks could aid in protecting your lungs from smoke, the number one recommendation from experts is to stay indoors. According to Health Canada, the following measures should also be taken: Reduce sources of indoor air pollution (smoking, vacuuming, burning candles, wood stoves) Prevent infiltration of outside air (seal windows, instal a high-quality air filter, set HVAC system to recirculation mode, limit use of exhaust fans when not cooking) Have a functioning CO alarm Use a portable air purifier and air conditioning Granton echoed this advice. "Most people recommend staying indoors as much as possible and not exercising or doing things outside," he reiterated.

Manitoba city records Canada's worst air quality of 2025: How wildfire smoke can impact health — and how to protect yourself, according to an expert
Wildfires in Western Canada have caused poor and at times dangerous air quality in certain parts of the country. Environment Canada has issued air quality warnings for parts of Alberta, Saskatchewan and Manitoba and is encouraging people, especially the elderly, pregnant people, children and people with chronic health conditions, to avoid spending time outdoors whenever possible. According to the Weather Network, Flin Flon, Man., a town located approximately 600 km north of Winnipeg, has registered the worst air quality rating in Canada this year. Canada uses the Air Quality Health Index (AQHI) to measure air quality on a scale from 1-10+. Environment Canada notes the city's air quality remains 10+, while the U.S. Air Quality Index (AQI) reported Flin Flon's air quality at a 312 out of a scale of 1-500, the highest AQI reading for Canada in 2025 (it has since lowered to below 300). Evacuations are underway. Cots are going up. The wildfire situation is serious — but like always, we'll get through it together. 🤝🆘 Donate to the @redcrosscanada — Wab Kinew (@WabKinew) May 31, 2025 As of June 1, the Canadian Interagency Forest Fire Centre reported 181 active fires in Canada, with 91 considered out of control.
