Coronavirus case reported at Father F.X. O’Reilly Catholic School in Tottenham, Ont. “This behaviour is concerning and affects the safety of all staff and students when they come back to school after their lunch,” Catherine McCullough said in the letter.“Please be advised that schools will not accept notes from parents/guardians who wish to excuse their child from the building for lunch.”McCullough said the new measure is meant to help keep students in their cohort for the rest of the day and to limit their unnecessary contact with others.
