An electrical problem has closed a Waterloo high school on the second day of classes.
Officials say there was a malfunction which damaged the electrical systems at Sir John A. Macdonald on Tuesday evening.
As a result all classes were cancelled on Wednesday and the school is closed to both staff and students.
Officials say contractors are on site working on a repair and they hope to have the school open on Thursday.
According to the school board the malfunction had no impact on other nearby schools or homes.
