A small riot broke out in the Saint-Jérôme detention centre's maximum security wing last night around 8:30 p.m.
Corrections officer union president Stéphane Lemaire said tensions are spilling over into violence because of constant overcrowding in the province's detention centres.
It took three hours to get the situation under control.
No one was injured during the event.
A group of inmates at the Hull jail held police at bay for eight hours after barricading themselves inside their wing last week.
