 James Darby was the last mayor of this city, from 1967 to 1978.On March 25, 1978, Notre-Dame-du-Sacré-Cœur was annexed to the city of Brossard to solve the problem of providing sufficient services to and maintaining an adequate municipal government for such a small geographical area.Notre-Dame had strong ties with the city of Brossard as its territory was almost completely surrounded by Brossard and its schools were served by the Brossard school board.
