At least two people are dead after a massive thunderstorm swept across much of southern Ontario today.
Peel Regional Police say a woman died after being hit by a toppled tree in Brampton, Ont.
Ontario Provincial Police also say one person was killed and two others were injured after a tree fell on a camping trailer near Pinehurst Lake in Waterloo Region.
The storm, which cut through a wide swath of southern Ontario on the first day of the May long weekend, also left thousands without power, according to Hydro One.
The storm was severe enough for Environment Canada to issue a broadcast-intrusive emergency alert that goes out to television and radio stations and mobile phones.
Environment Canada meteorologist Daniel Liota says the winds of 132 kilometres per hour measured at the Kitchener, Ont. airport were enough of a risk to property and life to trigger the alert warning.
