On July 8, 2013, severe flash flooding hit Toronto after an afternoon of slow-moving, intense thunderstorms. Toronto Hydro estimated 450,000 people were without power after the storm and Toronto Pearson International Airport reported of rain had fallen over five hours, more than during Hurricane Hazel. Within six months, from December 20 to 22, 2013, Toronto was brought to a near halt by the worst ice storm in the city's history, rivalling the severity of the 1998 Ice Storm (which mostly affected southeastern Ontario, and Quebec). At the height of the storm, over 300,000 Toronto Hydro customers had no electricity or heating. Toronto hosted WorldPride in June 2014, and the Pan American Games in 2015.
