The school was built in 1960 for the Commission des écoles catholiques de Québec. It was first named École Saint-François-Xavier. In 1984, it changed hands and became the property of the Eastern Quebec Regional School Board, and a French Protestant (evangelical) school named Nouvelle-Vie was established in the building. In July 1997, due to the linguistic school board shuffle, the building became the property of the Commission scolaire de la Capitale. In 2001, the government decreed that schools could no longer benefit from special religious status and the school closed. It remained closed for two years during which time two organizations rented the facilities – ‘Les Éclairs de Québec’ and ‘l’Église Évangélique de Québec’.
In January 2003, the Minister of Education of Québec allowed the Central Québec School Board to purchase the property and open a new school to alleviate overcrowding at the elementary school level in the Quebec city region. Therefore, Everest’s students came from four different schools: Dollard Des Ormeaux, Holland, Ste-Foy and St.-Vincent.
Central Québec School Board undertook major renovations – two washrooms were added, the 4 existing ones were totally renovated, lockers were sanded, painted and installed in the hallways, 2 offices, a library, a cafeteria and a kitchen were added and each classroom was refurbished and painted. Everest Elementary School opened its doors in September 2003, complete with new desks, chairs, audio-visual equipment, computers and miscellaneous teaching materials to the great pleasure of students and parents alike. In 2006 and 2007, a portable section was added to the school to give more space for offices and classes. In 2014 the trailers were replaced with a two storey structure containing 4 classrooms, washrooms and three offices.
