The hundred days as it later became know was started by the battle of Amiens. The Canadians used innovate tactics and even openly refused to follow the orders of the British to spearhead that attack, the ones that followed including the most important which was the crossing of the Canal du Nord, and defeat the Germans.
The Hundred Days was a good example of combined arms operations, but what makes you think it was a Canadian innovation?
It was after all the British who developed tanks, which were rather important to combined arms operations.
The Hundred Days describes the British and Commonwealth combined arms offensive against the Germans, not just Canadian operations. The battle of Amiens consisted of 8 British divisions, 4 Canadian divisions, 5 Australian divisions, 2 US infantry regiments, and the French 1st Army, all under the cmmand of the British 4th Army. A British General, Rawlinson, was in command.
The Australian and Canadian Corps each contained 1 of the British divisions.
The British also supplied over 400 tanks, and the combined allied air forces over 1,000 aircraft.
