Canada's first large-scale interior mall was built in the northern stretches of Metro Toronto, at the intersection of the MacDonald Cartier Freeway and proposed Spadina ["spuh-diy-nuh"] Expressway. YORKDALE CENTRE, housing one hundred stores and services, opened for business February 26, 1964. It was anchored by Toronto-based Eaton's and Simpson's.
