With the union of the Methodist, Congregational and many Presbyterian churches, the old Wesley Methodist Church on Church St (Royal York Rd) became vacant as a new United Church was built on Mimico Ave. The Town of Mimico purchased the old Methodist Church which served as the Town Hall. In 1922, Mimico's Baptist Church was built. Many bungalow style -storey homes were built in the interwar years, especially south of Mimico Avenue, and most notably, the tree-lined 'crescent' streets (Lake Cres, Eastbourne Cres, Dartmouth Cres and Lake Shore) were developed with large cottage–style homes. In 1928 the local streetcar line merged with the Toronto Transit Commission (TTC) which at first combined the line with Toronto's 'Queen' line.
