“Hot and humid air can bring deteriorating air quality and can result in the Air Quality Health Index approaching the high risk category,” Environment Canada added in its release.

“The risks are greater for young children, pregnant women, older adults, people with chronic illnesses and people working or exercising outdoors.”

Recommendations to beat the heat include drinking plenty of water, limiting activities, dressing to protect from the sun, never leaving children or pets alone in closed vehicles, and checking on neighbours, family and friends.

“It’s dry for most areas on Saturday, but Sunday could be a different story,” said Farnell. “We start to get into the risk of showers and storms in the afternoon and then Monday, potentially another round of heavy rain.”
