The first heat event of the season has prompted Environment Canada to issue a special weather statement for most of southern Ontario.
A warm and humid airmass is expected to move into Toronto and the GTA on Monday, pushing the daily maximum temperature into the low 30s. The overnight low is expected to be near the low 20s.
“These conditions pose a health risk when you are not used to the heat,” said the national weather agency. “Everyone is at risk from heat, especially older adults, infants, young children and people with chronic illnesses.”
Environment Canada advises people to drink plenty of liquids before you start feeling thirsty and to keep cool by dressing for the weather and spending a few hours each day in a cool place.
On Sunday, Environment Canada issued a special air quality statement for Toronto and the GTA, warning of possible high levels of air pollution due to the hot and sunny conditions.
