In December 1920 at Westminster Presbyterian Church, the members of the Waldie family erected a plaque in honour of brothers Lieutenant Walter Scott Waldie and Second Lieutenant Charles Percival Waldie. Lieutenant Waldie died on February 19, 1919, while serving with the Canadian Infantry (Central Ontario Regiment). Second Lieutenant Waldie died on September 26, 1915, while serving with The Queen's (Royal West Surrey Regiment).

On January 30, 1920, the church and plaque at 45-49 Bloor Street East were destroyed in a fire.
