The paper mill at Saguenay is the oldest one in Quebec. Opened in 1896, it produced wood pulp for newspapers, like how the mill in Trois-Rivières supplied for the New York Times. The mill reached its peak in 1910 when it was renown for its high pulp quality, it closed in 1930.

It was difficult to build industrial buildings along a river. They had to be positioned to take advantage of the water flow to power the machinery, but also on stable enough ground to support the weight of the heavy equipment.

Churches, schools, and houses sprang up behind the mill. The church and the workers’ union cooperated to build educational institutions for the children of the workers. The community became a town inside the city with peripheral businesses serving the mill’s employees. Much of worker housing was sold to them by the pulp company, land cost between $200 to $400 while land with a house cost up to $600 in the 1900s.

Today, the mill is a ruin. Only the 1921 building is used as the museum and an art gallery. The 1903 building is completely exposed without a roof and only half of the 1912 building is covered and used as event space.
