The Canadian Environment Ministry issued heat warnings in four provinces on Tuesday, including Ontario, Manitoba, Saskatchewan, and Quebec.

Temperatures can reach 30 degrees Celsius in parts of northwestern and northeastern Ontario, with humidity making it feel closer to the mid-thirties, according to the Canadian Environment Ministry, with similar conditions expected in southwestern and southeastern Ontario.

The city of Toronto will keep seven public pools open until around midnight on Tuesday to help residents cool down during the heat warning.

Heat warnings remain in effect in parts of northern Manitoba, where wildfires have led to additional air quality notices due to smoke.

The Canadian Environment Ministry also issued an air quality statement for the area around the city of Lytton, British Columbia, where a large blaze has grown to 20 square kilometers.

Meanwhile, parts of southern Manitoba may experience severe thunderstorms on Tuesday, which could create conditions conducive to tornadoes, according to the Canadian Environment Ministry.

Some communities in the province recorded record temperatures over the weekend.

The city of Dominion, located about 80 kilometers south of Winnipeg, recorded its hottest temperature on July 17 ever, reaching 34.2 degrees Celsius, surpassing the previous record of 32.2 degrees Celsius set in 1942.

Also, McCreary, located about 200 kilometers northwest of Winnipeg, set a record that day with temperatures of 31.9 degrees Celsius, surpassing the record of 31.7 degrees Celsius recorded just last year.

Lake Shoal, about 250 kilometers west of Winnipeg, recorded temperatures of 31.2 degrees Celsius, with its previous record on July 17 being 30.9 degrees Celsius in 2011.

In Saskatchewan, heat warnings are largely limited to the central and northern parts of the province, with temperatures expected to approach 30 degrees Celsius, according to the Canadian Environment Ministry.

Parts of Saskatchewan experienced periods of severe weather, including cold, heavy rain, and severe lightning on Sunday.

Heavy rain on Monday night also caused flooding in parts of Regina. Heat and humidity may make parts of southern Quebec feel like 40 degrees Celsius or more.

The cold front moving across the province may also cause showers and thunderstorms. Across the pond, temperatures reached record levels in the United Kingdom, exceeding 40 degrees Celsius for the first time.
