Before each Remembrance Day ceremony, Public Works and Government Services Canada (PWGSC) repairs and levels stones in the area of the war memorial, fills joints, waxes the bronzes, and applies a protective coating to the lettering on the Tomb of the Unknown Soldier. Plywood is placed over surrounding flower beds and approximately 6,000 metres of cable is run to connect sound systems and 12 television cameras. Any mementos or pictures attendees leave at the memorial following the ceremony are given to the Canadian War Museum for review and possible storage, while any money left is donated to The Perley & Rideau Veterans' Health Centre.[1]
