The Canadian Corps was a World War I corps formed from Canada's soldiers in September of 1915 after the arrival of the 2nd Canadian Division in France. The corps was expanded by the addition of the 3rd Canadian Division in December of 1915 and the 4th Canadian Division in August of 1916. In February of 1917 the organization of a 5th Canadian Division began but in February of 1918 before it was fully formed, it was assimilated with the others.

The Canadian Corps was originally commanded by British Lieutenant General E.A.H Alderson until 1916 when another British Lieutenant General Julian Byng took over. When Byng was promoted to an Army command, he was succeeded by the commander of the 1st Division, General Arthur W. Currie, giving the corps its first Canadian commander.

In the later years of the war, the soldiers of the Canadian Corps became, alongside those of the Australian Corps, the "shock troops" of the British Empire armies on the Western Front. The Corps captured Vimy Ridge in one of the most successful and daring attacks of the war. In 1918, the Canadian Corps fought in the Battle of Amiens between August 8 and 11th, inflicting a significant defeat on the German Army, called by German commander-in-chief, General Erich Ludendorff, "the black day of the German army."

The Canadian Expeditionary Force lost 60,661 dead during the war.
