Extreme heat and cold
Environment and Climate Change Canada (ECCC) issue both heat and cold weather warnings to allow people and communities to prepare to avoid serious health effects from extreme weather temperatures.
It is important to be prepared for severe weather by:
- Limiting travel during severe weather events, unless necessary
- Monitoring the weather forecast
- Preparing for emergencies in advance
Extreme cold |
ECCC will issue cold weather warning when the temperature or wind chill is expected to reach -35°C for at least two hours. Recommended precautions include wearing multiple layers of clothing, covering exposed skin, staying hydrated, and maintaining a heated indoor environment. Vulnerable groups, such as older adults and people experiencing homelessness, should be checked on frequently to ensure they are in a safe and warm environment. During extreme cold events, it is important to protect pipes from freezing and to use space heaters safely. It is also important to watch for signs of frostbite and hypothermia and seek medical attention when necessary. |
Extreme heat |
ECCC issues heat warnings when there is a forecast of two or more consecutive days with with daytime maximum temperatures of 31°C or warmer, together with nighttime minimum temperatures of 20°C or warmer or when there is a forecast of two or more consecutive days with humidex values expected to reach 40 or higher. To protect yourself during extreme heat, it is important to drink plenty of water, limit time outdoors during the hottest part of the day, wear sunscreen and light, loose-fitted clothing, and seek shade or cool off in an air-conditioned space. Vulnerable groups, such as older adults and people experiencing homelessness, should be checked on frequently to ensure they are in a safe and cool environment. The Canadian Red Cross has more information on how to stay safe during heat waves. It is also important to watch for signs of heat illness. Heat stroke is a medical emergency, call 911 if you are caring for someone who has a high body temperature and is either unconscious, confused or has stopped sweating.
