The school was named after Armand-François-Marie de Charbonnel, who was the Roman Catholic Bishop of Toronto from 1847 to 1860.

[2] The property was eventually sold to University of Toronto's Delta Kappa Epsilon fraternity in 1964.

At that time the board was expected to approve a plan that would lease the existing high school, which was owned by the Congregation.

The district expected that 12 teachers and 235 students would be a part of the school and that there would be an annual operation cost of $225,000.

[4] In September 1985, the modern school, École secondaire catholique Monseigneur-de-Charbonnel was opened by the Conseil des écoles catholiques du Grand Toronto (CECGT), the French unit of the Metropolitan Separate School Board (MSSB), with 66 students on the St. Robert Elementary property.
