For many years
Royal Military College of Canada (RMC) cadets and other military groups have marched into St. George's for worship on special occasions. 'Copper Sunday', an annual church parade from RMC to St. George's, in which cadets took up a collection of copper coins, was established in 1882 or earlier. A memorial tablet was erected before 1899 to the memory of three officers, graduates of the Royal Military College of Canada, who died while serving in Africa: Huntly Brodie Mackay, Captain Royal Engineers; William Henry Robinson, Captain Royal Engineers; and
William Grant Stairs, Captain the Welsh Regiment, but was lost in the 1899 fire and was not replaced. In 1918, the Royal Military College's Great War Memorial Flag was presented to the rector of St. George's Cathedral, the Very Rev. Dean Starr, honorary chaplain to the college, by the then Commandant, Brig. General C. N. Perreau, C.M.G.. The 18 feet by 24 feet flag hung on the north gallery of the cathedral, until the summer of 1934, when it was removed to the college museum for preservation. 932 Maple leaves represent those graduates who served, and 147 crimson leaves represent those who paid the supreme sacrifice in the Great War. of the Royal Military College of Canada was placed in the cathedral in 1942. In a 1942 church parade ceremony, General Hertzberg asked permission of the churchwarden, RMC Professor W.R.P. Bridger to lay up the RMC colours in the cathedral. After the congregation were addressed by the Lord Bishop of Ontario, the cadet battalion marched back to the college. A virtual tour the Royal Military College of Canada gallery at the Cathedral Church of St. George features stained glass windows of several soldier saints including St. George. The most recent windows—the St. Cecilia window and the St. Margaret window—also in the RMC gallery, were installed in 2002 and 2003 respectively. ==Popular culture==
