Extreme heat can affect everyone's health. However, some people are at greater risk of heat stress and related illness, including death due to a combination of greater exposure, physical health, and reduced access to resources.
When municipalities take into consideration who is at greater risk, why they are at risk (e.g., work exposure, no access to air conditioning), and how to reach them (e.g., in-person outreach, telephone, media), extreme heat events can be better managed with targeted strategies to reduce heat health risks as identified below.
When Environment and Climate Change Canada (ECCC) issues a heat warning, Simcoe Muskoka District Health Unit's medical officer of health recommends affected municipalities activate their community engagement, communication, and community response components of the Heat Alert and Response System (HARS). These components require planning and coordination with other community partners prior to a heat event.
Municipalities play a significant role in reducing the risks of extreme heat. Preventative strategies that promote broad community health benefits, reduce exposure and sensitivity to heat, and increase people's ability to protect themselves during periods of extreme heat are necessary to reduce the negative health impacts caused by our changing climate. More information on preventative strategies can be found on the SMDHU's website.
