Smoke plumes from forest fires in northern Ontario could make it harder to breathe elsewhere in the province.
Environment Canada issued a special air quality statement Monday morning for Oxford County, Woodstock, Tillsonburg, Goderich, Bluewater, and southern Huron County, warning of high levels of air pollution. The deteriorated air quality is the result of the more than 30 active forest fires that are burning in northern Ontario, as well as those in Quebec, the national weather agency said.
The air quality health index (AQHI) risk is expected to remain moderate to high throughout the day Monday and into Tuesday.
"Air quality and visibility due to wildfire smoke can fluctuate over short distances and can vary considerably from hour to hour," Environment Canada said. "Wildfire smoke can be harmful to everyone’s health even at low concentrations."
Some steps that can be taken to help reduce exposure to the smoky air includes stopping or lowering activity if breathing becomes uncomfortable or if you begin to feel unwell, using a MERV filter in your home HVAC system, keeping doors and windows closed, and increasing water intake.
Deteriorating or poor air quality can lead to increased coughing, throat irritation, headaches or shortness of breath. It is particularly a concern for children, seniors, those with cardiovascular or lung disease, such as asthma, and people who work outdoors.
"People respond differently to smoke. Mild irritation and discomfort are common, and usually disappear when the smoke clears, Environment Canada said. "Contact your health care provider or local health authority if you develop severe symptoms or need advice."
The weather agency also advises residents to check in on those who may be more susceptible to the smoke and to reduce indoor air pollutants.
"If you can, avoid smoking or vaping indoors, burning incense and candles, frying foods, using wood stoves and vacuuming. Dust on indoor surfaces can be removed by wiping and wet mopping during a pollution episode," Environment Canada said.
