CommentsSouthern Ontario, June 22-23, 2015. A cold front that swept through southern Ontario after a warm low pressure system created severe isolated thunderstorms that brought intense lightening, heavy rain and strong winds. Heavy rainfall caused flooding in London, where there was up to 48 mm of rain and in Toronto, where the Toronto Pearson International Airport recorded 110 mm. Flooding in London overwhelmed the sewage system as well as caused damages to residential and commercial properties due to basement flooding. In Toronto, flooding caused road closures and delayed Go Transit. Strong winds and lighting downed trees, which caused damages to homes and power lines. Approximately 100,000 Hydro One customers (300,000 individuals) were without power during the storm.
