Longueuil

Longueuil is a city in the province of Quebec, Canada. It is the seat of the Montérégie administrative region and the central city of the urban agglomeration of Longueuil. It sits on the south shore of the Saint Lawrence River directly across from Montreal. The population as of the Canada 2016 Census totaled 239,700, making it Montreal's second largest suburb, the fifth most populous city in Quebec and twentieth largest in Canada.

Charles Le Moyne founded Longueuil as a seigneurie in 1657. It would become a parish in 1845, a village in 1848, a town in 1874 and a city in 1920. Between 1961 and 2002, Longueuil's borders grew three times, as it was amalgamated with surrounding municipalities; there was a strong de-amalgamation in 2006.

Longueuil is a residential, commercial and industrial city. It incorporates some urban features but is essentially a suburb. Longueuil can be classified as a commuter town as a large portion of its residents commutes to work in Montreal. Most buildings are single-family homes constructed in the post-war period. The city consists of three boroughs: Le Vieux-Longueuil, Saint-Hubert, and Greenfield Park.

Although a large chunk of Longueuil's workforce commute to Montreal, the city nevertheless offers many jobs in a diverse range of industries. Above all, Longueuil benefits from having very low property value despite its close proximity to Montreal.

Longueuil is particularly strong in the aerospace industry. It is home to the headquarters of both Pratt & Whitney Canada and Héroux-Devtek. Pratt & Whitney Canada is Longueuil's top employer with 5,000 employees, while Héroux-Devtek has 550 employees. Also located in Longueuil is the headquarters of the Canadian Space Agency (John H. Chapman Space Center), adjacent to Montréal/Saint-Hubert Airport. Pascan Aviation has its headquarters in Saint-Hubert, Longueuil. Other companies based in Longueuil include Agropur and Jean Coutu Group.
