In 1902, after the Government of Canada announced it would sponsor a major exhibition at the site in 1903, the Toronto City Council decided to rebuild the exhibition site. In 1903, the Government of Canada reached an agreement to transfer the remaining military reserve to the City of Toronto. Under the agreement, military uses were permitted to continue until such time that replacement facilities were built. Included in this was Old Fort York, which the City committed to preserve. The building campaign saw the building of fifteen permanent buildings designed by architect G. W. Gouinlock from 1903 until 1912, including the surviving Press Building, Horticulture Building, Government Building, Music Building and Fire Hall / Police Station. The new buildings were elaborately designed and set in an attractively landscaped site. At the conclusion of the building campaign, the name was officially changed to the Canadian National Exhibition. The five remaining buildings were declared a historic site in 1988.
