Canada’s Hundred Days is the name given to the series of attacks made by the Canadian Corps between 8 August and 11 November 1918, during the Hundred Days Offensive of World War I.

 To avoid the risk of having extensive German reserves massed against a single Allied attack, the assault along the Canal du Nord was undertaken as part of a number of closely sequenced Allied attacks at separate points along the Western Front.
 It began one day after the Meuse-Argonne Offensive, one day before an offensive in the Flanders region of Belgium and two days before the Battle of St. Quentin Canal.
