In 1955 the boom following the arrival of the Ford Motor company was being felt and the church expanded again. Completed in 1956, the new section along Dunn Street now includes the parlour the library, counting room, office, and the nursery. In 1965, a hall was built under the Church at a cost of $80,000, to provide additional space for the church school. It was named for C.K. McNicoll, the minister who guided Knox from its centennial in 1933 to 1961.
