John C. Munro Hamilton International Airport (IATA:YHM, ICAO:CYHM) is located in Hamilton, Ontario, Canada.

Hamilton's airport was built at its present site in October 1940 as a wartime air force training station.

The airport was originally designed as a multi-purpose military field and was used for flight training, air navigation, telegraphy, and air gunnery.

In the period between 1945 and 1963, a gradual uncoordinated transition from military establishment to a public facility occurred at Hamilton Airport.

In 1963, Department of National Defense announced the Hamilton Airport at Mount Hope surplus to its needs and the Department of Transportation assumed ownership and control.

The John C. Munro Hamilton International Airport is named after John Carr Munro who was first elected to the Canadian House of Commons in the 1962 election, and served continuously as a Member of Parliament (MP) for Hamilton, Ontario in the electoral riding of Hamilton East until his resignation in 1984.

Today, the John C. Munro Hamilton International Airport is Canada’s largest dedicated courier / cargo airport.
