When Nazi Germany attacked Norway on 9 April 1940, with only a small number of modern aircraft on order from US manufacturers taken on charge, the Royal Norwegian Air Force (RNAF) was unable to mount a sustained defense. Following the defeat of the Norwegian forces, the King, key members of the government and military left Norway in June 1940 aboard the HMS Devonshire.
After arriving in England, the Norwegian government-in-exile began the process of setting up a new base of operations. A decision was swiftly made to keep the existing Norwegian pilots that had escaped to England, as an independent unit, consequently, none were allowed to participate in the Battle of Britain. Arrangements were made to transfer Norwegian pilots to a North American headquarters while various locations were considered, a base around the Toronto Island Airport in Canada was chosen. Once the base was established, young Norwegians migrated to the site to enroll in the RNAF in Canada.
In 1939, Bernt Balchen, a Norwegian aviator, enlisted with the Norwegian Air Force and made his way to the United States on a crucial mission to negotiate “matters pertaining to aircraft ordnance and ammunition with the question of the Norwegian Government’s possible purchase of such materials in the United States of America.”  With his status of holding dual Norwegian and American citizenship and his extensive contacts in the aviation industry, his instruction from the Norwegian Government-in-exile in London changed to a new directive: to set up a training camp and school for expatriate Norwegian airmen and soldiers in Canada.Balchen negotiated directly with Canadian government officials to obtain an agreement to use available airport facilities at the Toronto Island airport on Lake Ontario known as “Little Norway”.
