 Over time, the area east of Yonge Street which was formerly part of the Lansing postal village was developed into residential suburbs and came to be considered part of Willowdale instead of Lansing.The Lansing area was developed into a residential neighbourhood of mostly single-family owned and occupied homes between 1910 and the 1950s.In the older portions nearest Yonge Street the homes are one- and two-storey pre-war houses while in the newest areas homes consist of modest one-and-a-half-storey postwar houses.
