Environment Canada has issued a heat warning for much of southern Ontario.

Daytime high temperatures are expected to be in excess of 30 C, with humidex values in the high 30s to low 40s.

Environment Canada says this prolonged heat is expected to stick around until at least Sunday, and will likely persist into early next week.

“[It] can result in the Air Quality Health Index approaching the high-risk category” the statement reads.
