Smaller 3-storey apartment buildings went up on almost every street while larger apartments appeared along much of the Lake Shore on the east side. More commercial space was also built especially on the northern side of Lake Shore Road from Mimico Ave. to Burlington St. A period of church expansion occurred with Christ Church Anglican and St. Leo's Roman Catholic Church building new Churches at this time for larger congregations. St. Leo's new church was built on the site of Mimico's 1858 Post Office which was demolished and shortly after the postmaster's home (Werden House) was purchased to become the new rectory. In 1958, the Presbyterian Church built a new church building beside the old church. A legion hall was established in Mimico in Sir Henry Pellatt's former Bailey House.
