Part of the Centre de services scolaire Marguerite-Bourgeoys (CSSMB), it was originally in the catholic School board Commission scolaire Sault-Saint-Louis before the 1998 reorganization of School boards from religious communities into linguistic communities in Quebec.

[1] In 1967, the ministère de l'Éducation du Québec implement the concept of "écoles polyvalentes" arising from the Parent Commission Report published between 1963 and 1966.

It is in this political context that the École polyvalente Cavelier-De LaSalle was created and the school will be inaugurated in 1964 with some extensions made afterwards.

The school is named after the area's first lord and French explorer Robert René Cavelier de La Salle (born at Rouen, France in 1643, died in Texas USA in 1687).

The school contained mainly regular classrooms, science labs, plastic art workshops, a cafeteria, a library and an auditorium.
