In the first month of the First World War, Canadian military officials began planning for an internment camp, to be located at the Exhibition Grounds in Lethbridge. Renovations were completed to convert the horse stables and poultry building into living quarters, and to add a barbed wire fence. The facility was opened on September 30, 1914, and in mid-1915 it became a first-class camp designated for non-working prisoners who were primarily German or German-speaking Austrians.
