While Montreal has grabbed headlines for its plan to dump eight billion litres of raw sewage into the St. Lawrence River, 100 other municipalities regularly discharge their wastewater into Quebec's waterways without treatment or filtration.

CBC has obtained a complete list of all municipalities and which river basins they dump into. The Quebec government had previously said that there were 101 municipalities, but have reduced it to 100 after further study.
