Extreme heat events are prolonged periods of unseasonably high temperatures. It is responsible for more weather-related deaths in Canada in an average year than any other hazard.

Climate change is making extreme heat events more common.

Impacts of extreme heat
- Heat-related illness and death, particularly among vulnerable populations
- Ecosystem stress for marine and land species
- Increasing energy costs because of the need for cooling
Extreme heat doesn't affect everyone equally. Disproportionally impacted populations include:
- Seniors
- People with disabilities
- People with pre-existing health conditions
- People who are socially isolated
How we’re responding

Building the future we want

A city that is resilient to extreme heat means:

Improved access to cooling and thermal safety at home
Better access to public cooling spaces and community supports
Expanded tree canopy and green space, particularly in neighbourhoods disproportionately impacted by the urban heat island effect
