By 1919, the church was ready to expand again, and the sanctuary was renovated to assume the form that exists today. The old organ was replaced with a new $6,625 three-manual Casavant Organ, the chancel was extended through the arch and the stained glass window of the Last Supper was installed in memory of the men in the congregation who died in the Great War, including the son of the minister. The window was donated by Cecil Marlatt, owner of a great family tannery, who died 8 years later bankrupt. These renovations, which cost $20,300, also saw the addition of what is now R.G. MacMillan Hall. The 1925 Union crisis and the creation of the United Church of Canada, along with the Great Depression, brought about a period of hard times for the church and it wasn't until 1949 that the congregation could hold a mortgage-burning ceremony.
