St. Paul's Presbyterian Church was the Regimental Church of the 91st Canadian Highlanders from 1903 – 1931. The Cross of Sacrifice, unveiled in 1921, commemorates the First World War fallen of St. Paul's Presbyterian Church.
The large Celtic Cross was carved in Edinburgh, Scotland, and is similar to the ancient crosses in Iona where Christianity was first brought to Scotland from Ireland by St. Columba. The arms of the Cross are shortened, the column tapers from its base to the top and a sword pointing downward is in the center. A circle symbolical of a crown or wreath surrounds the arms.
After the Second World War, names of the congregation's fallen from that war were added.
