The current school was established by the Society of Jesus in 1930 and it succeeded a previous Jesuit college which was founded in 1634.

However, the parish had been previously handed over by the Jesuits to the Archdiocese of Quebec and any land for expansion was sold off, so the college was moved to a newly constructed building.

On 7 August 1944, the Archbishop of Quebec, Jean-Marie-Rodrigue Villeneuve ordered the establishment of a new parish dedicated to St. Charles Garnier and the founding pastor was Canon Alphonse Morel.

It publicly made the commitment to ′use the entire building and goods exclusively for the continuation of the work of training and education at St. Charles Garnier College, in a spirit of quality and rigour in the Jesuit tradition and in the context of a private Catholic institution'.
