A downburst reaching between 80 and 90 km/h managed to tip over two houses under construction in Brampton, Environment Canada says.
Two new houses on Quintette Close in the Countryside Drive and The Gore Road area were damaged after strong wind gusts and heavy showers on Wednesday evening, Peel Regional Police reported.
The houses were damaged by a downburst, Environment Canada said Thursday.
A downburst is "a strong burst of wind that flows downward and outward from a thunderstorm," CBC Toronto meteorologist Colette Kennedy said.
"While these winds can be stronger than tornado winds at times, the primary differences are the vertical flow (tornado core) versus more horizontal with a downburst," she said.
"Tornado winds flow in as opposed to out like with a downburst."
Toronto and parts of the Greater Toronto Area, including Brampton, were under a special weather statement for strong wind gusts and small hail Wednesday evening.
