July 16, 2012 — Close to 90 mm of rain fell in Scarborough on Sunday leading to basement flooding and a large sinkhole. Lightning also grounded planes at a Toronto airport.
Sunday was an active day across much of southern Ontario as severe storms fired up throughout the region.
Callers to The Weather Network Stormline reported frequent lightning, rumbles of thunder and heavy rain.
Several areas saw localized flooding after the heavy downpour, but Scarborough was the worst hit area in the GTA. Close to 90 mm of rain fell in a short period of time, leading to basement flooding and a massive sinkhole. The sinkhole opened up near Cedarbrook in the Markham Road and Eglinton Avenue area.
Water spread onto many other major roads across Toronto, but officials say traffic moved in both directions following the storm Monday morning.
In Whitby, a lightning bolt sent 17 people to hospital with non-life threatening injuries.
Flights were also suspended at Toronto's Billy Bishop Airport during the height of the storm.
Bryan Caballero, a passenger en route to Montreal, says that at one point, water was coming through the doorway of his plane.
"We couldn't even see the CN Tower," he said, speaking to The Weather Network from the tarmac, where his flight was temporarily grounded.
He said that passengers weren't allowed to leave the plane during the storm due to nearby lightning strikes.
A second round of storms fired up in Vaughan and the east end of Toronto Sunday evening.
