Don Mills, North America's first self-contained suburb, was the earliest planned city to include a full compliment of residential, commercial, educational, medical, religious and industrial facilities. Developed between 1953 and 1965, the ultra modern metropolis had a shopping mall as its commercial core. This depiction from early 1954 shows the retail hub as it was originally envisaged.

A vintage view of the initial section of DON MILLS CENTRE. The architecture of the complex incorporated a minimalist modern style.

In a second snapshot, we see the east end of the 350-foot shopping concourse. The entrance of a Dominion grocery store is seen on the right. This supermarket opened, in February 1955, as the shopping hub's first operational tenant.
