Extended Heat Warning

Based on information from Environment Canada, Dr. Eileen de Villa, Toronto’s Medical Officer of Health, has upgraded the Heat Warning to an Extended Heat Warning, until further notice.

During an Extended Heat Warning, members of the public are encouraged to visit family, friends and neighbours, especially isolated adults and seniors who are at greater risk of suffering from heat-related illness, to make sure they are cool and drinking plenty of fluids. Other groups at risk include people with chronic illnesses, individuals with limited mobility or certain mental health illnesses, infants and young children, people on certain medications, and those who are homeless.

In addition to swimming pools, beaches and air-conditioned shopping malls, Toronto has 170 air-conditioned community centres and local libraries in neighbourhoods across the city. For homeless and under-housed people, there are also 50 drop-in centres that are available at various hours seven days each week.

The following seven locations offer an air-conditioned place to rest indoors and receive a cool drink and light snack. Staff who are trained to assist residents affected by the extreme heat are on hand at the seven locations:
• Metro Hall, 55 John St. (24 hours)
• East York Civic Centre, 850 Coxwell Ave. (11 a.m. to 7 p.m.)
• North York Civic Centre, 5100 Yonge St. (11 a.m. to 7 p.m.)
• Driftwood Community Centre, 4401 Jane St. (11 a.m. to 7 p.m.)

Members of the public are also advised to beat the heat by taking these precautions:
• Drink lots of cool water even before you feel thirsty.
• Go to air-conditioned places, including shopping malls, local libraries and community centres.
• Take cool showers or baths or use cool, wet towels to cool down.
• Wear loose, light-coloured, breathable clothing and when outdoors wear a wide-brimmed hat.
• Avoid the sun and stay in the shade or use an umbrella.
• Reschedule or plan outdoor activities during the cooler parts of the day.
• Never leave seniors, children or pets unattended in a car.

Landlords of buildings without air conditioning are encouraged to provide a dedicated cooling room for vulnerable residents to escape the heat. Community agencies are encouraged to educate clients on the risks of heat-related illness and to call or check on those clients at increased risk of heat-related illness during warnings.

When a warning is declared, those who need assistance or have heat-related inquiries may call 311.
