Soon after the building became a royal residence, additions to accommodate the viceregal party and household were required, including a ballroom and sunroom. These, however, were on 2 February 1976 destroyed by fire and the other rooms of the residence suffered smoke and water damage. The Department of Public Works and Government Services Canada (which oversees the infrastructure of the Citadelle) restored the original wing and new state rooms were built in place of the lost post-1872 additions, the work being completed in 1984.
