Eastdale Secondary School in Welland, also part of DSBN, has an outbreak after two people tested positive, forcing five classrooms to close.

Mustafa Hirji, Niagara's chief medical officer of health, previously said 15per cent of Niagara's population is either a student or school staff member.

Thatmeans roughly one in every seven cases will be linked to a school.

Two schools in Brantford and one in Waterdown are the most recent school-related COVID-19 cases.
