}}

On 28 May 1916, Byng took command of the Canadian Corps from Lieutenant-General Sir [[Edwin Alderson]]. Discussions for a spring offensive near Arras began, following a formal conference of corps commanders held at the [[First Army (United Kingdom)|First Army]] Headquarters (HQ) on 21 November 1916.{{sfn|Nicholson|1962|p=245}} In March 1917, the army HQ formally presented Byng with orders giving Vimy Ridge as the Canadian Corps objective for the Arras Offensive.{{sfn|Brennan|2007|p=94}}

A plan, adopted in early March 1917, drew on the briefings of staff officers sent to learn from the experiences of the French Army during the Battle of Verdun.{{sfn|Brennan|2007|p=94}} For the first time the four Canadian divisions would fight together. The nature and size of the attack needed more resources than the Canadian Corps possessed and the British [[5th Infantry Division (United Kingdom)|5th Division]], artillery, engineer and labour units were attached to the corps, bringing the nominal strength of the Canadian Corps to about 170,000 men, of whom 97,184 were Canadian.{{sfn|Nicholson|1962|p=229}}
