   Current Heatwave Conditions in Toronto

   Toronto is currently experiencing a prolonged and intense heatwave, with temperatures consistently exceeding 30°C (86°F) for the past week. Environment Canada has issued a special weather statement, warning residents of the potential health risks associated with prolonged exposure to extreme heat.the heatwave is impacting daily life across the city, from increased demand on the power grid to concerns about vulnerable populations. This summer heat is particularly notable as it follows a relatively mild spring, leaving many unprepared for the sustained high temperatures.
