Smoke from wildfires in western Canada is expected to reach Renfrew County, west of Ottawa, according to Environment Canada. Reuters
A special air quality alert covers eastern Ontario and western Quebec. Environment Canada issued the warning Thursday. It says wildfire smoke will lower air quality and reduce visibility tonight and into Friday morning. Health risks will be high during this time.
Health Risks and Safety Tips
The alert warns that as smoke builds up, health problems can increase. It advises people to spend less time outside and to delay outdoor sports and events. “You may feel eye, nose, or throat irritation, headaches, or a mild cough,” the alert says. “More serious symptoms like wheezing, chest pain, or severe cough can happen. Seek medical help if needed.”
The warning stretches as far west as Lake Huron, south to Toronto and Windsor, and north past Gatineau, Quebec.
People over 55, pregnant women, outdoor workers, and those with health issues face the highest risks from wildfire smoke. These groups should stay indoors and avoid smoke.
How to Stay Safe Indoors
When inside, keep doors and windows closed to block smoke. If a heat wave happens alongside poor air, focus on staying cool. The alert suggests using good air filters in ventilation systems or certified portable air cleaners to keep indoor air clean.
People who must be outside should wear a respirator mask like an N95 or similar, which can filter tiny harmful particles.
Wildfires Still Burning in the Prairies
The alert comes as wildfires rage in the Prairies. Manitoba has declared a national emergency. Many First Nations people from Manitoba are leaving their homes and traveling far away for safety. Some have reached Niagara Falls, hundreds of kilometers from their communities.
This wildfire smoke spreading over Ontario and Quebec is a serious health concern. Following the advice to reduce outdoor time and protect indoor air will help keep people safe.
