Environment and Climate Change Canada (ECCC) issued a heat warning on Tuesday, May 27.
The warning comes as temperatures are expected to reach 29 C on Wednesday and leading into Thursday night.
"Take action to protect yourself and others. Extreme heat can affect everyone’s health," wrote ECCC. "Determine if you or others around you are at greater risk of heat illness."
The group asks that residents watch for the early signs of heat exhaustion, which includes headache, nausea, dizziness, thirst, dark urine, and intense fatigue. They also ask that residents call 911 if they see anyone who is showing signs of heat stroke.
"Drink water often and before you feel thirsty to replace fluids," added ECCC. "Close blinds or shades and open windows if outside is cooler than inside. Turn on air conditioning, use a fan, or move to a cooler area of your living space."
The group gave some other tips on how residents can protect themselves, including:
- Rescheduling outdoor activity.
- Taking frequent breaks from the heat.
- Drinking plenty of water.
- Checking for children and pets before leaving a vehicle.
"Pay particular attention to individuals that can experience earlier or more severe effects from heat including infants, children, seniors, and individuals with pre-existing lung, heart, kidney, nervous system, mental health or diabetic conditions, outdoor workers, as well as those who are socially isolated."
Heat warnings are issued when very high temperatures are expected to pose an elevated risk of heat illness.
