It was a soggy first day of school for students and parents in southern Ontario Tuesday. 

A low pressure system pushed across the region, bringing record amounts of rainfall and thunderstorms to the province. In some places, so much rain fell so quickly that it led to localized flooding. 

By 2 pm, more than 78 mm of rain had fallen in Markham. Stouffville was soaked with more than 86 mm, and 35 mm of rain was recorded at Toronto's Pearson International. 

Daily rainfall records were broken at Pearson, Buttonville and Hamilton airports Tuesday. The rain, accompanied at times by thunder and lightning, also led to flight delays coming in and out of Pearson. 

The Toronto and Region Conservation Authority issued a flood warning for low-lying areas on Tuesday afternoon. The warning was cancelled before 10 pm.

Meanwhile, in the Ottawa area, a sinkhole swallowed a car on one of the city's highways.
