On December 15, 1919, at St. Jude’s, Roncesvalles Church, a stained-glass window was dedicated in honour of its 14 parishioners who lost their lives in the First World War. The ceremony was performed by Assistant Bishop of Toronto, William Day Reeve. Constructed by Luxfer Prism Co., the window was installed in the north wall of the church. It is a reproduction of James Clark's The Great Sacrifice, which is at St. Mary Magdalene’s Church, in London, England. The window depicts a fallen soldier touching the feet of Christ, who is crucified on a tree beside the soldier, looking down on him.
The original St. Jude’s opened in 1890 at 437 Roncesvalles Avenue in Toronto. After the new church was built in 1912, the original building served as the parish hall until 1929, when it was demolished to make way for a larger hall. In 1977, the parish was disestablished and the building was demolished in 2004. The St. Jude’s, Roncesvalles First World War Window was moved to a new St. Jude’s in Brampton which opened in May 1980.
