 After gaining the trust of the Canadian government, he became Chief Censor for war-time Canada from 1942 until 1944; Eggleston's predecessor, Major James Haig-Smith, was ordered to ban some 600 published works due to leftist sympathies. Among the high-profile censorship requests that Eggleston didn't oblige to include the Battle of the St. Lawrence, after he discovered that it was merely an attempt to, as he put it, "give the Minister of Naval Affairs a scoop when he announced it to the House", and the Conscription Crisis of 1944, to which he was personally objected, despite pressure from then Prime Minister, Mackenzie King. Upon being discharged from the post, General Léo Richer Laflèche commented in the Ottawa Citizen that he was "largely responsible for the efficient functioning of censorship in Canada". He was succeeded in the role by fellow journalist Fulgence Charpentier.
