A stained glass window was dedicated to Captain Thomas George Beagley of the 14th Battalion (Royal Montreal Regiment) in the Church of the Ascension. The window depicts a knight praying at an altar before leaving for battle, his helmet and shield by his side; in front of him he holds his sword, the shape of the weapon echoing the symbol of his faith.

The Church of the Ascension became surplus and was put up for sale in 1988. The City of Montreal acquired the building in 1992 to relocate the local public library.
