Get ready for more wildfire smoke to waft into Ontario by Saturday

Northwesterly winds will drag a notable plume of wildfire smoke into Ontario to start the long weekend

Cooler weather arrived in Ontario with an unpleasant side effect into the day Thursday. Northwesterly winds lowered temperatures while increasing the amount of smoke blowing over the region.

Folks who are sensitive to lower air quality should use caution over the next couple of days—especially on Saturday, when another notable plume of smoke will push into the province.

Ontario smoke path Saturday

Wildfire smoke from northern Saskatchewan and Manitoba is riding the jet stream directly toward the Great Lakes region, lowering air quality across much of Ontario.

Air quality levels and a distinct smoky smell filled the skies over much of the province through the day Thursday. While Friday should bring some clearer skies, the smoky conditions may be far from over.

Favourable winds will sweep another push of wildfire smoke across most of Ontario heading into our Saturday.

Given the trajectory of the smoke, cottage-goers and campers may be more affected by the smoke than folks staying in southern Ontario. Very thick smoke is likely north toward Moosonee.

Wildfire smoke can cause respiratory problems in those who suffer from chronic illnesses or respiratory diseases. If possible, stay indoors during periods of reduced air quality, and consider wearing a mask outdoors to reduce your exposure to fine particulate matter.
