Ontario’s eerie orange skies and thick blanket of wildfire smoke are the result of a rare combination of weather conditions coming together at the same time, according to Environment Canada climatologist David Phillips.
Phillips told Yahoo Canada that a heat dome that moved north from the United States into the Great Lakes region helped create the conditions that allowed smoke from wildfires in northwestern Ontario, Manitoba and other parts of Canada to settle across the province.
The high-pressure system acted almost like a “vacuum cleaner,” pulling smoke that was higher in the atmosphere down closer to the ground, creating the dark, hazy conditions that left many residents describing the skies as something out of a movie.
“It was almost like a movie set from the Twilight Saga,” Phillips said, describing the scene as “dark, dank and morose.”
Unlike typical wildfire smoke that can stay high in the atmosphere and create colourful sunrises and sunsets, Phillips said this event was different. The combination of northwest winds and the heat dome trapped smoke closer to the surface, reducing visibility and pushing air quality levels into dangerous territory.
Phillips said Ontario’s wildfire season arrived late this year, but residents shouldn’t expect the threat to disappear anytime soon.
“The fire season has been late,” he said. “The key thing is wind directions.” He added that dry conditions, heat and the potential for lightning activity mean wildfire risks remain a concern.

As smoke crossed the Canada-U.S. border, some Americans took to social media to blame Canada for the hazy skies. Phillips pushed back on that idea, joking that he was “waiting for Americans, from Chicago to Boston, to complain about Canada causing these fires to burn.”
He pointed out that smoke travels both ways, with fires in states like California, Washington and Oregon also affecting Canada in previous years.
“The weather doesn’t stop at the international border,” Phillips said. “It just flows like it’s supposed to.”
Phillips said conditions should gradually improve as winds shift and help flush smoke out, with cooler temperatures expected next week. But he warned the smoke could return depending on wind direction, meaning residents may need to remain alert as wildfire season continues.
