The North York Civic Centre is a building in Toronto, Ontario, Canada that once served as the city hall for the former City of North York. Designed by Adamson Associates Architects, the building is located on Yonge Street north of Sheppard Avenue, and features Mel Lastman Square along the Yonge Street frontage. The construction of the building was intended to act as a catalyst for the development of the "North York City Centre", a downtown area for the formerly suburban North York.
