Toronto's Heat Relief Network: What You Need To Know To Stay Safe This Summer

As temperatures continue to climb across Toronto, the City is reminding residents that extreme heat is more than just uncomfortable—it can be dangerous, and even life-threatening for some people.

With heat warnings becoming more frequent due to climate change, Toronto has expanded its Heat Relief Network, making it easier for residents to access cool spaces, drinking water and other essential resources throughout the summer.

Heat affects everyone differently

While anyone can experience heat-related illness, some people face a much higher risk.

According to Toronto Public Health, older adults, infants and young children, pregnant people, individuals with chronic medical conditions, outdoor workers, people experiencing homelessness, and those without access to air conditioning are among the groups most vulnerable during periods of extreme heat.

Heat-related illnesses can develop quickly. Symptoms include:

Dizziness
Headaches
Nausea
Fatigue
Confusion
Muscle cramps

In severe cases, heat stroke is a medical emergency. If someone becomes unconscious or confused or stops sweating despite being overheated, call 911 immediately.

More than 500 places to cool down

One of the City's biggest resources is the Heat Relief Network, a collection of more than 500 cooling spaces available across Toronto.

These locations include:

Public libraries
Community centres
Civic buildings
Indoor pools
Splash pads
Select shopping malls
YMCA locations
Other community partner facilities

Unlike previous years when cooling centres were only opened during heat emergencies, many of these locations are available throughout the entire summer, giving residents more opportunities to escape the heat before it becomes dangerous.

During Heat Warnings, the City also opens a 24-hour cooling space at 136 Spadina Road for anyone needing immediate relief.

Simple ways to protect yourself

Toronto Public Health recommends several easy steps to reduce your risk during hot weather:

Drink water regularly—even if you don't feel thirsty.
Wear light, loose-fitting clothing.
Plan outdoor activities in the early morning or evening.
Spend a few hours in an air-conditioned or shaded space each day.
Close blinds and curtains during the hottest part of the day.
Limit the use of ovens and other appliances that generate heat.
Take cool showers or use damp towels to lower your body temperature.
Never leave children, older adults or pets inside parked vehicles.

Look out for one another

Extreme heat can be especially dangerous for people living alone or those who have limited mobility.

The City encourages residents to check in on:

Elderly neighbours
Friends and family with chronic illnesses
People without access to air conditioning
Individuals experiencing homelessness

If you encounter someone outdoors who may need assistance during a heat event, you can call 311 to request outreach support. The City also increases outreach services and access to shelters, respite sites and cooling spaces during Heat Warnings.

Heat waves are becoming more common

Climate experts have warned that longer and more intense heat waves are becoming increasingly common as the climate changes. Toronto's Heat Relief Strategy aims to reduce heat-related illness and deaths by expanding access to cooling spaces, educating the public and providing targeted support for vulnerable communities.

Whether you're heading to work, spending the day outdoors or simply trying to stay comfortable at home, taking precautions early can make a significant difference.
