The Middlesex-London Health Unit (MLHU) has issued a heat warning for the region, with temperatures expected to reach highs of over 30C for the next two days.
Environment Canada has also issued a heat warning for London and the surrounding area, with daily highs expected to hit 33C on Wednesday afternoon, with Humidex readings feeling more like 40.
Overnight lows are expected to fall to 20C before rising back to 31C on Thursday. Showers are also possible on Thursday, which is expected to moderate the heat.
While extreme heat can affect anyone, the National Weather Service says certain people are at greater risk.
“The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people who work or play sports outdoors,” Environment Canada said in a statement.
Residents are urged to drink plenty of water and stay in a cool place and never leave people or pets in a parked vehicle.
The MLHU heat warning is expected to be lifted Friday morning. The forecast for Friday is a high of 25C.
