Smoke from forest fires is responsible for poor air quality in southern Quebec, northern Ontario, Manitoba and Saskatchewan. Montreal is also on Saturday the city where air quality is the worst in the world, according to IQAir’s ranking.

With a score of 191, Montreal ranks first, ahead of cities like Kinshasa in Congo and Manama in Bahrain. Toronto is also part of the top 10, it ranks 8th with a score of 110.

A score between 101 and 150 on the IQAir index indicates that conditions are poor for vulnerable people. If the index is higher than 150, the conditions are bad for everyone’s health.

Smoke billowing from wildfires is leading to poor air quality and reducing visibility throughout most of Manitoba this weekend.

Environment and Climate Change Canada issued warnings Saturday morning for a large swath of the province, including Winnipeg and Brandon in the south, the Interlake and Thompson in the north.

“We have asthma so we try to just like think about how our chest is feeling … and go from there,” Aleecia Doyle said of she and her son, Liam Doyle. The pair ventured to Old Market Square to catch some of the entertainment for Winnipeg Fringe Theatre Festival opening weekend.

Saskatoon residents are feeling the lingering effects of the province’s northern wildfires on Monday, as a northerly wind has blown heavy smoke into central Saskatchewan.

Environment and Climate Change Canada issued an air quality warning after 4 a.m. Monday, advising anyone likely to be affected by smoke, including infants and young children, seniors, people with chronic conditions and those who work outdoors to limit time outside and seek medical attention if they experience symptoms.

The air quality index for the day is listed as 10-plus — considered a very high risk to health.

“During heavy smoke conditions, everyone’s health is at risk regardless of their age or health status,” Environment Canada said.

With the city once again blanketed in wildfire smoke, experts are warning that long-term exposure to air pollution can lead to higher risk of heart failure.

Environment Canada issued a special air quality statement on Sunday night due to wildfire smoke from northern Ontario pushing Toronto’s Air Quality Health Index to 10+, classified as “very high risk.” Poor air quality was expected to persist Monday and possibly into Tuesday.

The effects of air pollution on the heart are underscored in a recent study, which found that long-term exposure to air pollution, in particular fine particulate matter, was linked to higher levels of diffuse myocardial fibrosis, a type of heart scarring that can lead to higher risk of heart failure.

Toronto and much of the GTA are under a special air quality statement as smoke from forest fires in northern Ontario pushes into the region, Environment Canada warned Sunday night.

The agency says winds are carrying smoke into the area, reducing visibility and pushing the Air Quality Health Index to 10+, classified as “very high risk,” early Monday morning. Poor air quality is expected to persist into Monday and possibly Tuesday, Environment Canada added.

Torontonians are urged to reduce or reschedule strenuous outdoor activities, particularly if you experience coughing, runny nose, throat or eye irritation or any other symptoms.

People aged 65 and older, pregnant people, infants and young children, people with an existing illness or chronic health condition and people who work outdoors are most at risk, Environment Canada says, adding that more serious symptoms such as chest pain or severe coughing should be treated as medical emergencies.

Eastern Ontario is at the epicentre of a tick population boom, and with it, health officials are reporting the highest levels of Lyme disease in the province.

So far this year, there have been 186 confirmed cases of Lyme disease in south-east and Eastern Ontario, stretching from about Prince Edward County to the Quebec border, including Ottawa, according to Public Health Ontario. That is more than half of all the cases in the province since the beginning of 2025.

By far, the highest concentration of the tick-spread disease in the province is within the large South East Health Unit, which includes Smiths Falls, Brockville, Kingston, Belleville and Prince Edward County, among other regions. With 132 cases, it has the highest rate of Lyme disease in Ontario.

Ottawa, with 41 cases, and the Eastern Ontario Health Unit, with 13 cases, also have higher-than-average rates of Lyme disease. Those reported cases reflect the climate-driven growth of tick populations across the area and heightened risk of Lyme disease and anaplasmosis, which are both spread by blacklegged ticks carrying bacteria.

TORONTO — The Canadian Ophthalmological Society is urging people to take care of their eyes as wildfires burn across Manitoba and Saskatchewan.

People on the frontlines of the fires may get airborne particles in their eyes that need to be flushed out with sterile solution, said Dr. David Plemel, an eye surgeon in London, Ont., who was speaking on behalf of the society.

If it’s not easy to get the particle out, he recommends seeing an eye professional so they can remove it without damaging the cornea.

Smoke travels long distances and can affect people’s eyes even if they are far away from an actual blaze, said Plemel, who is also an assistant professor of ophthalmology at Western University.

Air quality warnings have been issued for a large swath of Manitoba, though rain could bring some much-needed relief.

Environment and Climate Change Canada (ECCC) upgraded a number of air quality statements to warnings Monday morning in a large portion of southern Manitoba, including Winnipeg, Steinbach, and Lac du Bonnet.

These areas join much of northern Manitoba, which have been under air quality warnings for days due to wildfires burning in the region and in northern Saskatchewan.

However, the weather agency notes smoke will improve with rain forecast through southern Manitoba on Monday, while northern communities under wildfire threat will likely have to wait until the weekend for precipitation.

The Air Quality Health Index (AQHI) for Brandon reached 10+, indicating a “very high risk” level on Saturday morning, as thick smoke was expected to linger in the air until Saturday night.

Environment Canada’s forecast anticipates that these hazardous conditions will persist through Saturday night, with only a slight improvement expected, dropping to a “moderate risk” (AQHI 6) by Sunday morning and a “high risk” (AQHI 7) by Sunday night.

The elevated readings are the result of thick wildfire smoke that drifted into Brandon Friday evening and remains heavy over the city Saturday morning. The smoke originates from wildfires burning in northern Manitoba and northern Saskatchewan and has led Environment Canada to issue a special air quality statement for the city.

A push by Donald Trump’s administration to repeal a barrage of clean air and water regulations may deal a severe blow to US public health, with a Guardian analysis finding that the targeted rules were set to save the lives of nearly 200,000 people in the years ahead.

Last week, Trump’s Environmental Protection Agency (EPA) provoked uproar by unveiling a list of 31 regulations it will scale back or eliminate, including rules limiting harmful air pollution from cars and power plants; restrictions on the emission of mercury, a neurotoxin; and clean water protections for rivers and streams.

During his last time in office, Trump botched the pandemic response, he spread misinformation everywhere, he contributed to restricting access to reproductive health care, he tried to repeal [the Affordable Care Act] and he set the world back on climate action. For me, it’s extremely worrying to have someone in charge with such a poor track record on health and science.

Wildfire smoke may increase the risk of dementia, study finds

Published July 29, 2024

Still COVIDing Canada Posts

Published by: The Guardian
Published on:

A new US study has found that wildfire smoke may be worse for brain health than other types of air pollution and even increase the risk of dementia.

The findings, reported on Monday at the Alzheimer’s Association International Conference in Philadelphia, come as millions spent the weekend under air quality warnings from wildfires spewing smoke across the western US, including a huge wildfire in California that has grown to more than 360,000 acres.

At issue is fine particulate matter or PM 2.5 – tiny particles about 30 times smaller than the diameter of a human hair that can be inhaled deep into the lungs and move to the bloodstream. This pollution – from traffic, factories and fires – can cause or worsen heart and lung diseases, and the new study adds to evidence it may play some role in dementia, too.
