In the 1940s, the John C. Munro Hamilton International Airport was a wartime air force training station. Today, managed by TradePort International Corporation, passenger traffic at the Hamilton terminal has grown from 90,000 in 1996 to approximately 900,000 in 2002 with mostly domestic and vacation destinations in the United States, Mexico and Central America. The airport's mid-term growth target for its passenger service is five million air travelers annually. The airport's air cargo sector has 24–7 operational capability and strategic geographic location, allowing its capacity to increase by 50% since 1996; 91,000 metric tonnes (100,000 tons) of cargo passed through the airport in 2002. Courier companies with operations at the airport include United Parcel Service and Cargojet Canada. In 2003, the city began developing a 30-year growth management strategy which called, in part, for a massive aerotropolis industrial park centred on Hamilton Airport. Advocates of the aerotropolis proposal, now known as the "Airport Employment Growth District", tout it as a solution to the city's shortage of employment lands. The closest other international airport to Hamilton is Toronto Pearson International Airport, located northeast of the city in Mississauga.
