Plans for an airport in Saint John date back to 1928, when in July it was decided that the city would be the site of the province's first municipal airport. At that time, $100,000 was allocated for initial development, which was to occur shortly thereafter. From 1928 to 1951, the Saint John Municipal Airport, located in Millidgeville, served as the city's aviation hub.
By the early 1940s, city councillors recognized the need for a larger airport, evidenced by the increased presence, size, and traffic of aircraft during World War II. They sought help from the provincial government to build a new, larger airport. In 1943, the current airport site underwent an engineering survey, following the creation of a search commission on May 15, 1943. The site, located east of the city, was 719 hectares in size and was purchased by the city on February 26, 1946, for $200,000. In December 1951, the original airport closed, and its land was later used for suburban housing development.
In March 1949, construction for the new airport began, although an agreement between the provincial government and the city was not finalized until March 20, 1950. On January 8, 1952, the Saint John Airport officially opened. Located on the eastern side of Loch Lomond Road, the airport was established in an area previously known as Clover Valley, which consisted of farmland and forestry prior to its development. The opening ceremony included preparations for a large air show to take place the following spring. The construction of the airport cost between $5 and $6 million.
