Ontario could see relief from wildfire smoke as blazes continue across north

People who have been wheezing and sneezing at the sight and smell of northern Ontario wildfire smoke this week could be in for some relief.

Environment Canada says the hazy, smoky conditions in some areas could temporarily improve today, but for others, they could persist into the weekend.

A slew of forest fires continues to burn across northern Ontario, with flames already razing communities such as Namaygoosisagagun First Nation, also known as Collins First Nation, north of Thunder Bay.

The Ontario government and the Assembly of First Nations have called on Ottawa to provide immediate support, while other provinces such as Alberta have deployed firefighters and water bombers to help.

Prime Minister Mark Carney has said his government is in close contact with its counterparts in Ontario and is ready to help as needed.

Officials say there are 136 active fires in the northwest region, with 63 out of control, along with another 44 in the northeast.

You may experience common, mild symptoms such as eye, nose, and throat irritation, headaches, or a mild cough. More serious but less common symptoms include wheezing, chest pains or severe cough. If you think you are having a medical emergency, seek immediate medical assistance.

People more likely to be impacted by wildfire smoke, 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 avoid strenuous activities outdoors and seek medical attention if experiencing symptoms.

When indoors, keep windows and doors closed as much as possible. When an extreme heat event occurs with poor air quality, prioritize staying cool.

Protect your indoor air from wildfire smoke. Actions can include using the highest-quality air filter your ventilation system can handle and/or a certified portable air cleaner that filters fine particles.
