The CSSPO was created after the former Commission Scolaire des Portages-de-l'Outaouais was abolished in 2020.
It currently runs schools in the Hull and Aylmer sectors of the city of Gatineau as well as in the municipalities of Chelsea, Luskville and La Pêche.
It also runs the école secondaire des Lacs in the municipality of La Pëche (Sainte-Cécile-de-Masham).
Overall, schools in the CSSPO area have a total of about 14 000 students in all levels.
The centre had a foundation called "La Fondation CSPO" in which it accumulated proceeds from the general population in its jurisdictional territory in order to realize various projects across the territory, such as leisure or general activities, parent and student assistance, bursary or infrastructure upgrades.
