Environment Canada has issued an air quality statement for much of northeastern Ontario, including areas in and around Greater Sudbury, North Bay, Sault Ste. Marie and Timmins.
'Smoke is causing or expected to cause poor air quality and reduced visibility,' the statement said Saturday.
'High levels of air pollution due to smoke from forest fires are expected to return tonight and persist into Sunday. As smoke levels increase, health risks increase. Limit time outdoors. Consider reducing or rescheduling outdoor sports, activities and events.'
Symptoms caused by forest fire smoke in the air include eye irritation, headaches and mild coughing.
'More serious but less common symptoms include wheezing, chest pains or severe cough,' Environment Canada said.
'If you think you are having a medical emergency, seek immediate medical assistance.'
Keep windows closed
People more likely to be impacted by outdoor air pollution, including 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, should reduce or reschedule strenuous activities outdoors and seek medical attention if experiencing symptoms.
'When indoors, keep windows and doors closed as much as possible,' Environment Canada said.
'When there is an extreme heat event occurring with poor air quality, prioritize keeping cool.
If you must spend time outdoors, a well-constructed, well-fitting and properly worn respirator-type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke.
Check on others who are in your care or live nearby who may be more likely to be impacted by outdoor air pollution.

Alberta's wild weekend weather: More than 100 mm of rain in many areas

Environment and Climate Change Canada says many areas in the foothills and eastern Alberta saw more than 100 millimetres of rain over the weekend. (Pexels/Pixabay) Many regions saw more than 100 millimetres of rain from a weekend storm, Environment and Climate Change Canada (ECCC) says, while others reported as much as 30 centimetres of snow. The storm, which began on June 20, was focused mainly on the foothills and in many parts of eastern Alberta, the agency said. According to online data, the most rain – 131.4 millimetres – fell in Cappon, a rural locality south of Oyen. Other areas that saw more than 100 millimetres of rain over the weekend include: Azure (120 mm), Pekisko (116.1) and Stavely (114). The Calgary International Airport and Canada Olympic Park each reported 69.5 millimetres of rain, ECCC said in its statement. ECCC also reported snow on June 21 in Kananaskis Village and near Bragg Creek. According to social media, 30 centimetres reportedly fell in the Highwood Pass. The agency said third-party websites reported 109.7 millimetres of rain in Bragg Creek, 106.4 millimetres of rain in Eden Valley and 80.5 millimetres of rain in High River. ECCC said the storm also brought high winds, with the windiest region being Milk River, where gusts of 87 km/h were recorded.

Intensifying heat dome over parts of Eastern Canada fueling unpredictable weather in the West

Blame the heat dome hanging over Ontario and Quebec for some of the strange weather hitting other parts of the country. Article content Environment Canada meteorologist Julien Pellerin says scorching temperatures over the eastern part of the continent are causing below-normal temperatures in other regions, which have led to warnings of wet snow and heavy rain in the West. Article content Article content Article content 'If you have a heat dome on a sector, you can expect colder air in another sector, so that's what the Prairies are currently experiencing,' Pellerin said on Sunday. Article content Article content 'It's coming from the United States, a high-pressure system that doesn't move quickly … so it brings intense heat and moist air over southern Ontario and southern Quebec, and it'll settle there for the next three days.' Article content The dangerous temperature levels span from southwestern Ontario towards North Bay, Sudbury and Timmins, while in Quebec, the highest temperatures are expected from Montreal to Shawinigan and north up to Abitibi. Pellerin says he expects Ontario and Quebec to hit their peak daytime highs on Monday and Tuesday with temperatures rising above 30 C, and the humidex making it feel more like 40 to 45 degrees, depending on the region. Article content 'It won't last very long,' he added. 'By the end of Tuesday and Wednesday, we will have a transition in air mass all over Canada, especially over Quebec and Ontario.' Article content Article content Environment Canada warned of possible thunderstorms and tornadoes in northern parts of Ontario on the weekend. A dangerous storm ripped through the Mattawa area in northeastern Ontario late Saturday night, which caused the closure of Highway 17 between Bonfield and Mattawa.

'Heat dome' over Ontario and Quebec is causing wild weather across much of Canada

Blame the heat dome hanging over Ontario and Quebec for some of the strange weather hitting other parts of the country. Environment Canada meteorologist Julien Pellerin says scorching temperatures over the eastern part of the continent are causing below-normal temperatures in other regions, which have led to warnings of wet snow and heavy rain in the West. "If you have a heat dome on a sector, you can expect colder air in another sector, so that's what the Prairies are currently experiencing," Pellerin said on Sunday. "It's coming from the United States, a high-pressure system that doesn't move quickly … so it brings intense heat and moist air over southern Ontario and southern Quebec and it'll settle there for the next three days." The dangerous temperature levels span from southwestern Ontario towards North Bay, Sudbury and Timmins, while in Quebec the highest temperatures are expected from Montreal to Shawinigan and north up to Abitibi. Pellerin says he expects Ontario and Quebec to hit their peak daytime highs on Monday and Tuesday with temperatures rising above 30 C, and the humidex making it feel more like 40 to 45 degrees, depending on the region. "It won't last very long," he added. "By the end of Tuesday and Wednesday, we will have a transition in air mass all over Canada, especially over Quebec and Ontario." Environment Canada warned of possible thunderstorms and tornadoes in northern parts of Ontario on the weekend. A dangerous storm ripped through the Mattawa area in northeastern Ontario late Saturday night, which caused the closure of Highway 17 between Bonfield and Mattawa. Ontario Provincial Police said in a news release Sunday evening they helped evacuate approximately 290 people from two provincial parks in the area due to the storm, and the neighbouring Municipality of Calvin issued a state of emergency Sunday afternoon, warning residents in a social media post to avoid unnecessary travel due to downed trees, power lines and washouts disrupting local roads. Other parts of the country, meantime, are seeing surprises from the heat dome. On Saturday, Environment Canada warned that areas in British Columbia could face heavy showers, and over some of the highway summits, the possibility of wet snow. Heavy rainfall advisories that had been in effect in southern Alberta were all lifted by Sunday, but the region received significant precipitation. City residents were being warned to stay off the Bow River. The Calgary Fire Department advised against boating and all other water activities on the Bow due to higher-than-normal water flow, although the city said flooding over riverbanks was not expected. 'We know that Calgarians love their rivers, yet we also know that when our waterways flow this high and fast, there's significant risk to anyone, regardless of your watercraft or skill level,' Calgary Fire Deputy Chief Pete Steenaerts said in a news release. Saskatchewan's Water Security Agency warned the Alberta rain could also lead to increased flows on the South Saskatchewan River between the Alberta boundary and Lake Diefenbaker. The agency said Alberta began dumping water from reservoirs this past week to make room for the additional run-off. It expected lake levels at Lake Diefenbaker, a large reservoir northwest of Regina that's a popular recreation area, to rise over a metre this week as a result of the weather system. Heat levels in Ontario and Quebec led Environment Canada to remind people to stay hydrated by drinking water before they're thirsty, to watch for early signs of heat exhaustion and not overexert themselves. "Be careful; you know yourself," Pellerin said. "Make sure you're aware of what you're feeling and take breaks, Make sure you have a location where you can rest with the air conditioning." In Quebec, schools are being urged to stay vigilant with the rising temperatures. In a letter from the assistant deputy education minister, schools were encouraged to "put in place all the preventive measures you judge necessary to ensure everyone's security." "Depending on the situation, these measures could go all the way up to closing one or more schools for the day of June 23," said the message signed by Stephanie Vachon. This report by The Canadian Press was first published June 22, 2025.
