Ontario Braces for Scorching Start to Summer, Environment Canada Warns
As the summer solstice nears, Ontario residents face a sweltering start to the season, with a heat wave expected to bring soaring temperatures. Environment Canada forecasts highs exceeding 30 degrees Celsius across southern and eastern regions, prompting officials to issue warnings about heat-related health risks.
Heat Wave Intensifies
A heat wave is poised to grip much of southern and eastern Ontario, potentially driving temperatures into the upper 30s or even low 40s with the humidex, according to meteorologist Steven Flisfeder. Monday in Toronto might break the daily temperature record.
Impact and Precautions
The anticipated high temperatures pose health hazards, and people must stay safe. Overnight relief is unlikely, as temperatures are set to remain above 20 degrees Celsius through at least Tuesday night.
The forecast highlights the growing influence of climate change. The burning of fossil fuels has been demonstrated to increase the frequency and length of heat waves in Canada. Flisfeder urges people to take precautions to stay cool and avoid heat-related illnesses.

Rainfall warnings were in effect on Thursday for areas from the Bruce Peninsula to Parry Sound and North Bay.
As the summer solstice approaches, marking the longest day of the year, the heat wave serves as an immediate reminder of the changing climate. Residents are advised to prepare for potentially dangerous conditions.
