On January 14, 1988, the Protestant School Board of Greater Montreal (PSBGM) approved a community-based request to open a French Immersion alternative elementary school with a math/science concentration. The following September, Royal Vale Alternative School opened at 5540 avenue Dupuis.
In June of 1991, the first Grade 6 class of 28 students graduated. Then, in September 1992, the school grew to welcome three Secondary 1 classes, and it moved to its present location at 5851 avenue Somerled. Since 1988, the school has grown from 125 students to its present-day enrolment of over 900 students.
In June 2024, teachers Patricia Tarshis and Vincey Santalucia sat down to recall the early years of Royal Vale. They also shared fond memories of founding principal Susyn Borer, who passed away in April of the same year.
