Environment Canada has issued a heat warning for most of Ontario, including Toronto, Mississauga, Hamilton, Niagara, York, and Durham.
Much of Ontario, including the regions of Toronto, Mississauga, Hamilton, Niagara, York, and Durham, is under a heat warning as temperatures are expected to reach the 20 to 30-degree range over the next few days.
Early Tuesday morning, Environment Canada advised people to expect humid, hazy, and hotter-than-usual conditions that could feel more like 30 to 40 degrees.
This "multi-day heat event" is expected to last until Thursday.
David Phillips, Senior Climatologist at Environment Canada, said that much of Ontario, along with many parts of Quebec, is currently under a "big, big area of high pressure," which he called "the typical summer weather where we have the Triple H: heat, haze, and humidity."
