Environment Canada has issued an air quality statement for Hamilton, Burlington and parts of Niagara and area.
On Monday, the Air Quality Health Index was seven, or high risk, on Monday morning, and is expected to go down to five Monday evening.
"Smoke from forest fires over northern Ontario has moved into the area, causing the air quality to deteriorate," Environment Canada said Monday morning.
The high risk air quality could continue until Tuesday for some areas, according to Environment Canada. The weather agency recommends people limit outdoor time if possible, keeping doors and windows closed and using an air filter.
"If you must spend time outdoors, a well-constructed, well-fitting and properly worn respirator type mask (such as a NIOSH-certified N95 or equivalent respirator) can reduce your exposure to the fine particles in the smoke," said the statement.
The area is also in the middle of a heat wave that is set to last until Thursday that is seeing humidex values of 35 to 40, so Environment Canada recommends prioritizing staying cool.
Common, mild symptoms during an air quality statement include "eye, nose and throat irritation, headaches or a mild cough."
