Above, we have a late 1960 aerial view of the mall site. The original shopping centre is seen in the upper left corner. A newly-built South Wing extends toward the spaceship-shaped Curling Rink at the bottom of the image.

In 1961, the T. Eaton Company added a bona fide anchor store to the retail hub, which was now officially known as DON MILLS CENTRE. The 26th unit in the Toronto-based chain, the store was the first suburban branch built by "Eaton's of Canada".

By the early '60s, the centre has been expanded exponentially. Its vast, 2-level parking area can accommodate 4,000 autos. On this plan, the original mall is shown in black. A Dominion supermarket, Civitan Arena, Curling Rink and single-sided South Wing were completed in 1959 and 1960. These are shown in dark gray. Eaton's, a South Wing addition and freestanding cinema were finished between 1961 and 1963 and appear in light gray.
