The agency has issued a heat warning for an area stretching from London to Ottawa and extending to Sault Ste. Marie. Marie and as far north as Fort Albany.

The Greater Toronto Area and other southern parts of the province will see temperatures rise to 35 C starting Monday.

Environment Canada warns that the humidity will make the temperature feel between 40 and 45 C.

The weather agency says there will be little relief overnight, with temperatures remaining around 20 degrees or higher and humidity values ​​as high as 35 in parts of southern Ontario.

Much of southern Quebec is also under a special weather statement, as warm air will move eastward by the end of the week.
