An Ottawa Catholic elementary school in Nepean suffered severe damage during Saturday's major storm.

St. Monica School on Merivale Road has damage to the roof following the storm.

Photos from CTV News Ottawa's Peter Szperling show the roof of the one-floor school shifted off the building, a giant tree in front of the school and debris scattered across the property.

The Ottawa Catholic School Board said Tuesday the school is expected to remain closed for at least the remainder of the week.

The school board says damage was isolated mainly to the gymnasium area and a restoration company is onsite.

The board continues to assess all of the schools for damage after the storm moved through the city on Saturday afternoon, leaving a trail of damaged buildings, downed trees and broken hydro lines.
