The Winnipeg Grenadiers Colours were laid up in All Saints Anglican Church on 7 June 1965 and will remain in place until they disintegrate. Due to All Saints Anglican Church's proximity to Fort Osborne, in their early years All Saints was known as "the military church" and had quite a few military personnel as parishioners. The Regimental Colour hangs on the left side of the church and the Queen's Colour hangs opposite to it on the right side.
The Winnipeg Grenadiers originated in Morden, Manitoba on 1 April 1908. More than 7,000 men served with the Grenadiers in the First and Second World Wars and of these, three earned the Victoria Cross — two in the First World War and one in the Second World War. During the Defence of Hong Kong, soldiers from D Company of the Winnipeg Grenadiers became one of the first Canadian Army units to fight in the Second World War. Company Sergeant-Major John Robert Osborn of the Winnipeg Grenadiers earned a Victoria Cross at the Defence of Hong Kong where many Grenadiers became prisoners of war for more than three-and-a-half years, first in Hong Kong until early 1943, and then in Japan until their liberation in September 1945.
Following its destruction at Hong Kong, the 1st Battalion was reconstituted in Winnipeg in 1942 and participated in the attack on Kiska, Alaska in 1943. In 1944 the battalion deployed to Scotland for training and remained there until after the end of hostilities in Europe. Over the course of its history the regiment earned 22 battle honours, 20 for the First World War and two more for the Second World War.
