The 3rd Canadian Infantry Brigade was a formation of the Canadian Army in both World War I and World War II. The brigade fought on the Western Front during the First World War, and in Sicily and Italy during the Second World War.

Lieutenant General Sir Richard Ernest William Turner, was a senior Canadian Army officer who served during the Second Boer War and the First World War, and was a recipient of the Victoria Cross. While Turner always displayed great personal courage while under fire, he lacked the acumen for brigade- and division-sized tactics, and the men under his command during the First World War suffered grievous losses in several battles before he was moved into administrative roles.
