Since its creation in 1995, EVSL fosters the diversity of musical styles, whether profane or sacred music of the Renaissance, baroque, classical, contemporary and, to a lesser extent, extracts of musicals, folk songs and world music.

For its concerts, the choir prepares a cappella works, but mainly pieces accompanied by groups of professional musicians. Occasionally, and for the performance of greater choral works, the director invites some members or all members of other choirs he directs.

In addition to the year-end concert, which usually takes place in May, the EVSL occasionally performs Christmas concerts. Also depending on the needs and requests of organizations in the Saint-Laurent community, other concerts may be added during the season.
