In 1975, Massey Hall was municipally designated as a historic site under the Ontario Heritage Act. On 15 June 1981, Massey Hall was designated a National Historic Site of Canada. Starting in July 2018, Massey Hall underwent a two-year restoration project to restore and renew both the interior and exterior of the building, improve patron amenities and accessibility, open two new music venues, and enable the return of the building's original stained glass windows from 1894.
