On Saturday, January 11, 2020, southern Ontario was overwhelmed with a record-setting downpour, localized flooding, and freezing rain.
Rainfall records were broken across the province, as measured at some airports. Windsor received 50 mm of rain, which beat their previous record of 43 mm. Toronto just managed to break its previous 58.7 mm record with 59 mm of rain. Sarnia shattered its previous record of 29.6 mm with 61 mm.
The freezing rain followed. More than 20 mm of ice built up on surfaces in areas such as Shelburne and Hopeville.
I’m far upstream from @jwhittalTWN and the flooding is getting bad here in Grand Valley. Very dangerous, fast moving water. Please be very careful f you’re in the area. @weathernetwork @JSTAMOS #ONStorm pic.twitter.com/HnaH5pdzRz— Mark Robinson (@StormhunterTWN) January 11, 2020
On the Sunday morning, Hydro One said that more than 11,000 customers lost power. As Sunday grew colder, the standing water froze.

The Don Valley Parkway in Toronto was shut down from Bloor Street to the Gardiner Expressway, as the road had flooded. The water levels were so high that the London Fire Department had to rescue two people from the swollen Thames River.
