The 7th Canadian Infantry Brigade was an infantry brigade of the Canadian Army that fought during World War I and World War II. The brigade, along with the 8th Canadian Infantry Brigade and the 9th Canadian Infantry Brigade, formed the 3rd Canadian Infantry Division. The division was formed in late 1915 in France and served on the Western Front until the armistice in November 1918. Later, during World War II, it arrived in the United Kingdom in 1940 and spent three years in garrison duties and training in preparation for the assault landings on Juno Beach in Normandy on 6 June 1944. After fighting in Normandy, the brigade took part in the Battle of the Scheldt. After the war, it served on occupation duties until being disbanded in June 1946.
