PHOTOS: Damaging twister, weekend flash flooding hits southern Ontario
A raucous round of storms across southern Ontario left behind tornado damage and flash flooding in its wake this past weekend.
Saturday’s activity got off to a rough start when a tornado touched down around the communities of Drumbo and Ayr during the late morning hours.
CBC News reported no injuries in the aftermath of the storm, which heavily damaged at least one business and flipped several vehicles in the area.
Experts with the Northern Tornadoes Project gave it a preliminary rating of EF1. Based on tree damage along part of the track, there is a small chance it could be upgraded to EF2.
The same cluster of slow-moving storms continued into the Greater Toronto Area (GTA) through the afternoon hours, drenching the region with torrential rainfall that quickly led to pockets of flash flooding.
Multiple accounts on social media reported cars stranded in low-lying areas in Mississauga. Little Etobicoke Creek rose 3.1 metres in under two hours, triggering flooding along its banks.

Toronto-Pearson International Airport reported 128.4 mm of rain through 8:00 p.m. Saturday. This makes Saturday the rainiest day ever recorded at Pearson Airport, and this is now the station's rainiest summer ever observed.
Yet another round of storms led to more heavy rainfall and warnings across the GTA once again on Sunday. Intense rainfall rates and localized flooding stranded several vehicles on Highway 410. All lanes of southbound Highway 410 at Courtneypark Drive were closed until 3 a.m. on Monday to allow for drainage and damage recovery.
Firefighters are on-scene removing occupants from 5 stranded cars on Hwy 410 N/B. Once people were assisted to safety by our water rescue team, firefighters went to work clearing the catch basins to help the water slowly recede. MTO now on scene to take over the task. pic.twitter.com/rWqvrL4axy
