On January 30, 1921, a bronze tablet was unveiled in St. George the Martyr  at 205 John Street and dedicated to the 31 members of the congregation who lost their lives in the First World War, along with 258 men and several nurses who served in the war. The tablet was unveiled by Richard Waldron, the oldest member of the congregation, whose son had fallen in the war and while the ceremony was conducted by Bishop Farthing of Montreal and special preacher Bishop Bidwell.

During the early morning hours of February 13, 1955, a fire demolished much of the church.
