Heat Warnings

The Eastern Ontario Health Unit (EOHU) receives weather forecasts from Environment and Climate Change Canada (ECCC). Based on ECCC’s heat forecast criteria, and in keeping with the provincial Heat Warning and Information System, the EOHU will advise residents when the high heat or humidity is expected to last at least two days. During this time, heat warning notifications will be posted on the EOHU’s website as well as through social media to provide recommendations for how local residents can protect themselves and others from heat-related illnesses.

During Hot Weather Conditions

High temperatures can cause many health problems, including heat cramps, heat exhaustion, and heat stroke. (If you experience any of these symptoms, seek medical attention immediately.) During very hot weather, everyone is at risk, but some groups are more vulnerable than others. They include:

• Older adults
• Infants and young children
• People with chronic illnesses, such as breathing difficulties, heart conditions or psychiatric illnesses
• People on certain medications
• People who play sports or exercise outdoors
• People who work in the heat
• People who are homeless or who live in sub-standard housing

Fortunately, heat-related illnesses are preventable.
