Ontario Air Quality Among Worst In The World As Wildfires Continue

As Ontario’s wildfires continue to send thick plumes of smoke into the air, Ontario is struggling with the worst air quality in the world.

As of about 8 a.m. on Wednesday July 15^th, Toronto tops the list and the smoke is expected to linger through much of Thursday, as it expands across the U.S. northeast, including New York City and Washington. Smoke from northern Ontario wildfires has spread over 1,000 km, with the jet stream carrying it southeast. Hazy skies, diminished sunlight, and a smoky odour have been reported.

Here in the 705 region, residents have taken to social media to report haziness and the strong smell smoke. According to the Ontario – Air Quality Health Index (AQHI) – Environment Canada, risk in the area ranges from moderate to very high:

Very High Risk (Above 10): Barrie, Sault Ste. Marie, Thunder Bay

High Risk (7-10): Parry Sound, Sudbury

Moderate Risk (4-6): North Bay,

If you are in a moderate risk area, Environment Canada advises reducing or rescheduling strenuous activities outdoors if you are experiencing symptoms. There is no need to modify your usual outdoor activities unless you experience symptoms such as coughing and throat irritation.

However, in high risk areas, children and the elderly should take it easy, and consider reducing or rescheduling strenuous activities outdoors if you experience symptoms such as coughing and throat irritation.

If you are in an area with very high risk, avoid strenuous activities outdoors. Children and the elderly should also avoid outdoor physical exertion. Reduce or reschedule strenuous activities outdoors, especially if you experience symptoms such as coughing and throat irritation.

Environment Canada said smoke may cause 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,” Environment Canada said in its advisory.

Those at greater risk of health issues related to poor air quality include people over the age of 65, pregnant people, infants and young children, and people with existing illness or chronic health conditions. Early signs of heat exhaustion include headache, nausea, dizziness, thirst, dark urine and intense fatigue. If you experience these symptoms get to an air conditioned area and drink water.

Several municipalities including Huntsville, Lake of Bays, Bracebridge and Gravenhurst now have Extreme Fire Danger Ratings and have implemented fire bans. Under the Total Fire Ban:
