Canada’s summer heat wave continues this weekend with warnings issued in four provinces.
Environment Canada says Sunday’s highs in southern Ontario, southern Quebec, New Brunswick and Nova Scotia could reach or exceed 30 C and potentially reach the low 40s with humidity.
Heat and humidity warnings have been a theme this year, with some provinces and territories reporting record high temperatures.
Here are some of the heat records set so far this year:

Along with a series of recent fires, British Columbia saw days of record high temperatures across the province in late July.
Preliminary data showed the province broke eight temperature records – spanning several decades – on July 31.
Many of the records broken for the day were in the interior region of British Columbia, with Osoyoos reaching 40C on July 31, breaking the city’s 2003 record of 39.6C.
