Buckingham was a city located in the Outaouais region of the province of Quebec. Since January 1, 2002, it has been part of the amalgamated city of Gatineau which merged five former municipalities, including Masson-Angers, Buckingham, Hull, Aylmer and Gatineau, into a single entity. The 2006 population according to the 2006 Census is 22,078. Population growth has been relatively slow because of its location about 30 km from Downtown Ottawa. However, due to suburban growth and amalgamation of the town in 2002, several residential developments were created and the population increased. Buckingham is becoming more of a suburban town while still keeping its traditional characteristics in the centre-town area.
