Residents across Simcoe-Muskoka are being urged to take precautions as wildfire smoke drifts into the region, triggering the first Special Air Quality Statement of the year from Environment and Climate Change Canada.

The advisory, in effect through Friday, June 6, warns of potentially harmful effects from breathing in smoky air—even during short-term exposure.

Air pollution can affect everyone, but some people are more at risk, says the Simcoe Muskoka District Health Unit. That includes babies and young children, older adults, people who are pregnant, those living with chronic illnesses, and anyone who smokes or spends extended time outdoors.”

How to Stay Safe

The health unit is encouraging people to “stay aware, reduce exposure, and take care” as poor air quality continues.

Stay aware: Check the Air Quality Health Index (AQHI) often, as air conditions can shift quickly. “Keep an eye on symptoms in yourself and others, and know when it’s time to seek medical help,” officials advise.

Reduce exposure: If possible, stay indoors, keep windows and doors closed, and avoid strenuous outdoor activities. Those without air conditioning can seek out cleaner, cooler indoor air at local libraries, malls, or designated municipal spaces. “It’s important to protect indoor air quality,” the health unit says. DIY or portable air cleaners can also help.

Take care of yourself: Drink plenty of water and listen to your body. “If you feel unwell or are having trouble breathing, stop what you’re doing and rest,” the spokesperson added. The health unit also reminds residents that hot, humid conditions may overlap with smoky air—and heat usually poses the bigger risk. “If you must choose, staying cool should be your priority.”

Information about local clean air spaces and air quality tips is available through your municipality or by visiting the Simcoe Muskoka District Health Unit website.
