North York’s planning department prepared a series of maps tracing the municipality’s growth. The following description was provided for the 1965 map (population: 360,000):
“It was during the decade 1955 to 1965 that North York changed from being a dormitory community for Toronto’s labour force. It became a more integrated urban community with the introduction of industrial and commercial developments and the jobs these provided. By 1965 Don Mills was developed to its present extent. Yorkdale Shopping Centre had been opened in the western half of the borough. Development had almost reached the northern limits of the municipality at Steeles and left a few remaining pockets of undeveloped land south of Finch, such as Windfields Farm.”
