Advocates have expressed concerns for students and educators in Ontario classrooms as the province enters a major heat wave this week.

Environment Canada said Monday a heat wave descending on parts of Ontario this week is expected to bring dangerously high temperatures, some as hot as 45 C with the humidity.

Despite the soaring temperatures, students can still expect to attend their regular classes.

Earlier today, the Toronto District School Board (TDSB) announced that schools will remain open during a heat warning despite “uncomfortable conditions” in some schools without air conditioning.

Advocates and parent groups have raised safety concerns on behalf of students and education workers attending school during the heat wave.
