Toronto's heat warning, which had been in effect since earlier this week, was officially lifted by Environment Canada on Saturday, July 4, 2026. The warning ended as a cold front moved through the region, bringing more comfortable temperatures and lower humidity.
Forecast for the Next Few Days
According to Environment Canada, the forecast for Toronto calls for mainly sunny skies on Sunday with a high of 26°C. Monday will see a mix of sun and cloud, with a high near 27°C. Tuesday is expected to be sunny again, with a high of 26°C. There is a chance of showers on Thursday night, but the rest of the week looks mainly dry and seasonable.
Heat Warning Details
The heat warning was issued on Thursday, July 2, when temperatures soared into the low 30s with humidex values making it feel like 38°C. The warning covered Toronto and much of southern Ontario. “The heat warning has been lifted as a cooler airmass has settled into the region,” said Environment Canada meteorologist David Phillips. “Temperatures will be closer to seasonal norms for the next several days.”
Impact and Safety
During the heat warning, the city opened cooling centers and extended pool hours. No heat-related fatalities were reported in Toronto, but officials reminded residents to stay hydrated and check on vulnerable neighbors. The extreme heat also contributed to storm activity, with severe thunderstorms on Friday causing significant damage in parts of the city, including downed trees and power outages.
