Environment Canada’s heat warning remains in place for Guelph, Waterloo Region and Wellington County on Wednesday.
The heat warning, which was issued on Tuesday, calls for temperatures reaching the low-30s in the afternoon.
The thermometer is not expected to go below 20 C at night so there will be little respite from the heat until Thursday.

The high temperatures have brought poor air quality along with them, according to Environment Canada.
The agency also issued a ‘special air quality statement’ on Tuesday afternoon which came to an end late in the evening.
It is also warning residents to never leave people or pets inside of a vehicle which is turned off and says outdoor workers should take frequent rests.
