Killing heat is sitting over much of eastern Canada and the U.S. in what some meteorologists are calling a “heat dome.” Environment and Climate Change Canada has issued heat alerts for all of southern Ontario. In much of the region from Windsor to Toronto, it has forecast a high of 33 C with humidex values making it feel like 40 to 45. The Weather Network says it is 34 in downtown Toronto. As of 11.25 a.m. ET, the temperature had already hit 30.8 C at Toronto Pearson International Airport.
