In 1959, École secondaire Sacré-Coeur was founded, organized solely by these nuns and soon after, Eastdale Secondary School began offering French courses to its students.

In 1971 École secondaire Confédération's statistics grew exponentially, now serving nearly 900 students with 50 professors, [citation needed] leading to the construction of the south wing where a variety of workshops and classes are added.

Today, Confédération remains a unique French public secondary school offering a reputation and ambiance based on morals, culture, academics and athletics.

In 2006, 2007 and 2008, École secondaire Confederation qualified itself for the University of Ottawa Place à la Jeunesse provincial Marketing and Entrepreneurship competition.

Throughout the years the teams consisted of Martin Rocheleau, Chris Paley, Rohan Wahdwa, Michael Kenworthy, Justin Dallaire, Yannick Lieber, Xavier Léveillé, and David Richard.
