Smoky conditions continue to cover the GTA, but relief is expected in the days ahead
Poor air quality warnings due to wildfire smoke are still in place for the Greater Toronto Area on Tuesday for the fourth consecutive day.
Smoke from forest fires will continue to affect southern Ontario on Tuesday and possibly on Wednesday, Environment Canada said in a special air quality statement.
With clean air coming in from the east, air quality is expected to improve through Tuesday with "the worst of it" gone by Wednesday, says Lucas Alexopoulos, operational meteorologist with Environment Canada.
"We can expect some reduced air quality from forest fire smoke as we've seen the past couple of days. However, it shouldn't be as severe as it has been," he says.
The air quality statement is in effect for Toronto, Mississauga, Brampton, Newmarket, Burlington, Oakville, Halton Hills, Milton, Pickering and Oshawa.
Showery conditions are expected later in the week, which will help clear air quality, says Alexopoulos.
The clearer conditions brought down Toronto's ranking to fifth for the world's worst air quality on Tuesday morning, according to a global ranking by IQAir, a Swiss air quality technology company.

Vulnerable people should reduce time outdoors: Environment Canada
People with vulnerabilities, such as respiratory conditions, are advised to reduce their time outdoors and follow guidelines set by local authorities, says Alexopoulos.
Symptoms can include eye, nose, and throat irritation, headaches, and a mild cough. While it's not as common, Environment Canada says wheezing, chest pains or a severe cough are also potential symptoms.
The national weather agency is advising people to keep their windows and doors closed and check in on others who live nearby who are more likely to be impacted by outdoor air pollution.
The agency also suggests using a good quality air filter inside ventilation systems or a portable air cleaner to protect indoor air from smoke.

Health risks linger as smoky skies and poor air quality persist
The special air quality statement has been lifted in Waterloo Region, but we're not in the clear yet. CTV's Alexandra Holyk explains. Smoky skies from western wildfires continue to pose health risks even as the air quality improves. On Tuesday, Environment and Climate Change Canada (ECCC) lifted the special air quality statement for most of southern Ontario and eastern parts of the country. It was in place over the long weekend as the Air Quality Health Index (AQHI) reached an 8, which is considered 'high risk.' 'The situation with the air quality has improved, which is why we don't have the special air quality statement in effect,' said ECCC weather spokesperson Alexandra Cournoyer. 'However, we still have some level of fine particles in the air.' The fine particles are known as PM 2.5 and are made of various pollutants, including soot, smoke, dust, and other elements found in burning wildfires. They are invisible to the naked eye and can cause serious health risks if breathed in. 'They can enter our bloodstream and put some stress on our heart and lungs and other organs of the body,' said Dr. Matthew Tenenbaum, the associate medical officer of health for Wellington-Dufferin-Guelph Public Health. 'How bad those are depends on how much smoke is in the air, as well as how long you're exposed,' he added. Tenenbaum said while everyone is at risk, some may feel it more than others. 'If you have asthma, if you have COPD (Chronic Obstructive Pulmonary Disease) or existing lung disease, that can make it that much harder for you,' he said. The smoke can also be tough on those with seasonal allergies, who may notice an increase in nose, throat and eye irritation. As for how to avoid breathing in the smoke, health officials recommend using high quality respirators or masks. 'Staying indoors is the key thing to protect yourself,' said Tenenbaum. 2025 wildfire season on track to be second-largest Summer 2025 is shaping up to be the second-largest wildfire season on modern record, said Ze'ev Gedalof, an associate professor in geography at the University of Guelph. According to the Canadian Interagency Forest Fire Centre, as of Tuesday afternoon, there were 746 active wildfires burning across the country, causing smoke that has billowed through Canada over the last few months. 'This really is the new normal,' Gedalof said. Cournoyer said ECCC has issued more special air quality statements this year compared to 2024. 'It's not going to stop burning,' Gedalof said. 'The smoke is going to keep blowing downwind from the boreal forest in Ontario, Manitoba, Saskatchewan, Alberta and even into B.C.,' he added. Gedalof said it's because the forest is out of equilibrium with the climate that's driving it. 'When it experiences these long, hot, dry summers, plus any sort of ignition – whether it's a cigarette butt or an unattended campfire or a lightning strike – when it does ignite, it's going to burn.' However, he said there are ways to reduce risks. 'Most ignitions are human caused,' Gedalof noted. 'So the fewer fires we start, the less smoke we have to breathe.'

‘We've got you': School drives collecting supplies at Edmonton malls
The Pack the Pack initiative at Kingsway Mall aims to collect school supplies for Edmonton students. (CTV News Edmonton/Sean McClune) With back to school on the horizon, the cost of a child's school supplies list can be daunting for many families. But two initiatives are hoping to alleviate some of the pressure by collecting school supplies to be distributed to schools across the city. The Edmonton Public Schools Foundation (EPSF) has partnered with Kingsway Mall to 'pack the pack.' 'We are hoping to pack this backpack with new or unused school supplies in support of students this fall,' said EPSF acting director Catherine Bay. 'When students can start the year feeling prepared, they'll be a lot more confident in their learning.' A 'most needed' list of supplies is available on the EPSF website, and includes items like Duo-Tangs, notebooks, pencils, pencil crayons and binders. Bay said she's seen a need for supplies which has been growing every year. According to shopping lists from some Edmonton public schools, families with kids in elementary and junior high could be spending $50-$100 for a basic supply list. 'September tends to be a very expensive month for many families, and so the need just keeps increasing,' said Bay. 'Our goal is to be able to respond positively to students who do need that extra support. 'Don't worry, we've got you.' The drive is running until Sept. 6 at Kingsway Mall. SUPPLYDRIVE West Edmonton Mall is holding a school supplies drive until Aug. 17. (CTV News Edmonton/Sean McClune) But if you happen to be in the city's west end, West Edmonton Mall is also holding a drive in partnership with WEM Volkswagen and London Drugs to fill a bus with school supplies. Anna Alfonso, vice-president of marketing for West Edmonton Mall, said donations will be given to community partner Bent Arrow Traditional Healing Society and its family resource network. 'We are hoping for over 1,000 items donated,' said Alfonso. 'London Drugs has generously committed to providing backpacks and school supplies as well, and West Edmonton Mall is matching up to 100 items of school supplies donated.' SUPPLYDRIVE People can drop off new and unused school supplies at this Volkswagen van in West Edmonton Mall until Aug. 17. (CTV News Edmonton/Sean McClune) And while you might be picturing a big yellow school bus, the vehicle being filled is actually a Volkswagen bus that will be near Bourbon Street until Aug. 17. 'It's a fun play on what the city did with 'stuff a bus,'' said Alfonso. With files from CTV News Edmonton's Nahreman Issa
