A prolonged period of hot weather will continue today and into this week, Environment Canada said. Overnight lows near 20 C are also expected through this period, providing little relief from the heat. Meteorologist Ryan Rozinskis said a very warm air mass has settled into much of the province, including southern Ontario and the greater Toronto area. "Looking at that air mass, it's been in place for the last several days, and [will be] persisting for pretty much throughout this week," Rozinskis told CBC News. Additionally, Environment Canada says you should watch for the symptoms of heat illness.
