The warning is expected to remain in effect until Monday, when a cooler mass of air is expected to arrive.
The organization says that daytime temperatures are expected to be over 30 degrees, with humidex values in the high 30s. There is also not much relief overnight, with low temperatures anticipated to stay around 20 degrees.
It’s important to limit time outdoors and staying in a cool place. This may be helped by using fans or air conditioning.
Environment Canada is warning that extreme heat can have an impact on everyone’s health, with particular risk to older adults, and those with chronic health conditions or taking certain medications.
The signs of heat exhaustion include headache, nausea, dizziness, thirst, and intense fatigue. To prevent heat exhaustion, stop what you’re doing and drink water.
Heat stroke, meanwhile, has its own symptoms, which include red and hot skin, dizziness, nausea, confusion, and change in consciousness. Heat stroke is a medical emergency.
