If you're an Ontario resident who has noticed a haze affecting the skyline and sunsets in recent days, don't chalk it up to smog. It turns out the source is coming from much further away.

The haze many saw this week is actually smoke drifting in from wildfires raging throughout B.C., Alberta and Saskatchewan, says meteorologist Geoff Coulson.

"Even though these fires are over 2,500 kilometres away, it just points to the fact that the winds in the atmosphere have the ability to transfer the forest-fire smoke over great distances," Coulson told CTVNews.ca.

As winds carry the smoke into southern Ontario, it gives the atmosphere a hazy appearance and creates red sunsets and sunrises, Coulson said. "That reddish colour is actually the forest-fire particles in the atmosphere scattering the light."

But even though there is smoke in the province's atmosphere, Coulson said it's too high up to have an impact on air quality at this point.

Environment Canada has been monitoring air quality as the forest fires in the western provinces have intensified, and at this point, the agency doesn't believe Ontarians should be concerned.

Coulson said thunderstorms coming to Ontario on Tuesday afternoon will bring cooler air that will likely push the smoke into northern Ontario.

As for the West, their forecast doesn't look as promising, Coulson said.

"A big change isn’t expected in the Prairies," he said. "As long as it stays warm and dry, fires can continue or be more numerous."

Environment Canada continues to monitor air quality and is watching for any changes thousands of kilometres away. There are currently more than 110 wildfires burning in Saskatchewan and more than 180 burning in B.C.
