Special air quality statement in effect for London region
Haze hangs over downtown London, Ont. on July 31, 2025. (Bryan Bicknell/CTV News London) Environment Canada has issued a special air quality statement for the London region as wildfire smoke moves into the area. The areas it applies to are: Huron County Grey County Perth County Middlesex County Elgin County Lambton County Oxford County Environment Canada said air quality and visibility will vary as things can change quickly. To prevent any health risks, you are reminded to limit time outdoors, consider reducing or rescheduling outdoor sports, activities, and events. Mild and common symptoms to smoke exposure include: Eye, nose, and throat irritation Headaches Mild cough More serious symptoms are: Wheezing Chest pains A severe cough If you think you are having a medical emergency, you are to get immediate medical help.

Poor air quality expected to persist beyond long weekend in northwestern Ontario
Social Sharing Most of the province remains under air quality statements due to wildfire smoke from northern Ontario and the Prairies. Environment and Climate Change Canada (ECCC) issued the alerts on Sunday, which extend across the northwest. More severe air quality warnings have been issued for several First Nations in the region, including: Pickle Lake — Cat Lake. Pikangikum — Poplar Hill — MacDowell. Sandy Lake — Weagamow Lake — Deer Lake. Monica Vaswani, a warning preparedness meteorologist with ECCC, told CBC News on Sunday that there is a high ridge of pressure over much of the province, which is making it difficult for clean air to come through. "Unfortunately, what it does is it traps the pollutants and kind of makes them linger. There's a good chance we're going to continue to see these statements and in other communities, even warnings, through to at least Tuesday," Vaswani said. "Likely by Wednesday, there should be an improvement." Common symptoms of poor air quality include eye, nose and throat irritation, headaches or a mild cough. Those most at risk include children, older adults, pregnant people, those with underlying health conditions, and people who work outdoors. WATCH | Scientists concerned wildfire smoke may become increasingly toxic Scientists concerned wildfire smoke may become increasingly toxic 10 days ago Some scientists say more research needs to be done on what toxic chemicals may be re-released into the air, as climate change makes a type of wetland that naturally stores pollution more vulnerable to fire. One of the challenges in trying to prepare for poor air conditions is how quickly air quality can fluctuate, especially as wildfires are constantly evolving, Vaswani explained. Furthermore, "as the weather changes, the wind direction changes, and that can really determine exactly where that poor air goes," she said. People at higher risk of experiencing symptoms are encouraged to consider wearing an N95 mask outdoors and to use an air filter indoors to protect themselves from pollutants, Vaswani said. Ontario Forest Fires says the wildland fire hazard remains high throughout much of the region, with areas of extreme hazard in the western parts of the Kenora and Red Lake fire management areas. The Thunder Bay, Nipigon and Sioux Lookout sectors are seeing high to moderate hazards, it says. As of Sunday afternoon, there were 54 wildfires burning across northern Ontario. Of these, nine are considered not under control. Tracking long-term health effects Stephanie Charles is a health promoter in environmental health at the Northwestern Health Unit (NWHU), based in Kenora. She said it's hard to gauge the cumulative effects of ongoing air quality alerts on people's health. "We are able to look at epidemiological data, like you could see hospital admissions for those usually with pre-existing conditions — the COPD (chronic obstructive pulmonary disease), asthma, cardiovascular disease — and then you could overlay that with smoke events and smoke advisories," Charles told CBC's Up North. "The tricky thing about that is it's often lagging, so it's definitely an emerging science." While Thunder Bay and Winnipeg each have an air quality monitoring station, there are no such stations in areas in between, Charles said. To help bridge the gap, the NWHU has been working with ECCC and the University of Northern British Columbia to install particulate matter (PM2.5) air quality sensors in half a dozen locations in the region. "That also will help them to enhance their data they have on ground conditions for air quality, and hopefully lead to some better imaging or data management," said Charles. In the meantime, she said it's important for people to do their best to keep their homes insulated from the smoke outside. "Take it easy, don't overdo it, and just be mindful of the health symptoms," she said.

Forecasters predict Prairie wildfire smoke could cause hazy skies across Canada
A watercraft makes its way along the Ottawa river in Ottawa on Monday, July 14, 2025. THE CANADIAN PRESS/Adrian Wyld Wildfire smoke from the Prairies today is forecast to fill the skies from Vancouver Island to Charlottetown with gritty, hazy dust. Environment Canada says the smoke is causing or expected to cause poor air quality and reduced visibility that can fluctuate and vary hour by hour. The statements and warnings stretch from western British Columbia into eastern Prince Edward Island. Southern parts of the Northwest Territories, as well as much of Alberta, Saskatchewan, Manitoba and Ontario, also are affected. It comes as more than 700 wildfires burn across Canada, including one on the north banks of Cameron Lake in B.C., about 60 kilometres from the city of Nanaimo, that forced hundreds to flee. The weather agency says poor air quality can cause eye, nose and throat irritation, while more serious but less common symptoms include chest pains and a severe cough. This report by The Canadian Press was first published Aug. 3, 2025. Aaron Sousa, The Canadian Press
