The urban agglomeration of Longueuil was created on January 1, 2006 as a result of the de-amalgamation process brought upon by the Charest government. It encompasses all the boroughs that were merged into the previous city of Longueuil and still retains the same area as that mega-city.
The urban agglomeration of Longueuil is coextensive with the territory equivalent to a regional county municipality (TE) and census division (CD) of Longueuil, whose geographical code is 58.
In 2012, Longueuil mayor Caroline St-Hilaire proposed that the Urban agglomeration of Longueuil leave the Montérégie and become its own administrative region.[4]
Longueuil merged on January 1, 2002 with the communities of Boucherville, Brossard, Greenfield Park, LeMoyne, Saint-Bruno-de-Montarville, Saint-Hubert, and Saint-Lambert. These cities became boroughs of the Longueuil megacity. Saint-Lambert and LeMoyne combined to become one borough called Saint-Lambert/LeMoyne. The former city of Longueuil was renamed Le Vieux-Longueuil borough.
The former city hall of Brossard, became the city hall for the new city of Longueuil.
On June 20, 2004, the former boroughs of Boucherville, Brossard, Saint-Bruno-de-Montarville and Saint-Lambert voted to demerge from Longueuil to reconstitute themselves as municipalities on January 1, 2006. The rest of the city stayed intact.
The departure of Saint-Lambert from the city of Longueuil resulted in the immediate disbanding of the Saint-Lambert/LeMoyne borough. LeMoyne's small population and territory did not allow it to become a borough of its own. In 2005, the population of LeMoyne was given the choice to pick a new borough between Le Vieux-Longueuil, Saint-Hubert and Greenfield Park. Le Vieux-Longueuil ended up being the winner and amalgamated LeMoyne into its borough on January 1, 2006.
Following the demergers, Longueuil relocated its city hall from Brossard to Saint-Hubert, where it is still located.
According to the Act respecting the exercise of certain municipal powers in certain urban agglomerations, the cities and boroughs of the urban agglomeration of Longueuil are structured as follows:
| City/Borough | Population | Pct (%) |
|
| ||
|---|---|---|---|---|---|---|

| Saint-Hubert | 84,420 | 20.2% | ||||
| Greenfield Park | 16,735 | 4.0% | ||||
| Saint-Bruno-de-Montarville | 26,394 | 6.3% | 1 | 1.13 | ||
| Saint-Lambert | 21,861 | 5.3% | 1 | 1 | ||
| Total | 415,347 | 100.0% | 10 | 17.73 |
See main article: Urban agglomerations of Quebec.
Under this new system of municipal organization, the agglomeration city and the reconstituted cities (in this case, Boucherville, Brossard, Saint-Bruno-de-Montarville and Saint-Lambert) share powers and responsibilities. The urban agglomeration is headed by an agglomeration council which exercises these agglomeration powers.
