On March 7, 1920, three bronze tablets were unveiled honouring Chalmers Presbyterian Church parishioners who had given their lives in the First World War and those who fought and returned home. The first two tablets, made in duplicate, bear the names of those who made the supreme sacrifice in the war. The third and largest tablet bears the names of 280 men and women who served during the war and returned safely.
The church sanctuary at 1266 Dundas Street W was destroyed by fire in 1945 and was rebuilt. In 1978, the congregation merged with St. Paul's Dovercourt Presbyterian Church and the church on Dundas Street was demolished in the 1980s.
