The Rockcliffe Pavilion was constructed in the Arts and Crafts style, in 1917 by the Ottawa Improvement Commission, which was created by federal statute that became law in August, 1899 and replaced by the National Capital Commission in 1959. The Government of Canada recognized the Rockcliffe Pavilion as a Federal Heritage Building on October 27, 1994. The property, owned by the City of Ottawa until 1995, had its titles transferred to the National Capital Commission. At that time the pavilion was in very poor and much deteriorated condition. The National Capital Commission began restoration of the pavilion in 1997. Original materials and colour palettes were identified from historical studies and site investigations. The work was completed in 1998.
