 The final stage of training at Camp Borden involved a major joint exercise that pitted 4.000 infantry and units of machine gun, engineering, transport and armour in an attack and defence of a key strongpoint.The realistic war game showed how the training at Camp Borden resulted in the Canadian Active Service Force being ready and able to take their place on the battlefields across the world.Typical of the NFB's "Canada Carries On" series of morale-boosting propaganda short films, "Letter from Camp Borden" was made in cooperation with the Director of Public Information, Herbert Lash.
