List of infantry battalions in the Canadian Expeditionary Force

During the First World War, the Canadian Army authorized the formation of 260 infantry battalions to serve in the Canadian Expeditionary Force. Only a small fraction of these battalions ever reached France to serve on the front lines. The remaining battalions, most often upon arrival in England, were broken up and primarily absorbed into a reserve battalion. In addition to the numbered battalions were two named battalions, and several regiments of Canadian Mounted Rifles were converted to infantry battalions and served in the Canadian Corps.

Besides the infantry, there were other Canadian combat units in the CEF, including cavalry regiments (in particular the Canadian Cavalry Brigade), artillery brigades and machine gun battalions.

The infantry battalions in bold type served in the field.
