Effectively the Trois-Rivières museum of industry, Boréalis is housed inside the former water treatment plant of Canadian International Paper. There used to be four paper plants in the city with the CIP being the last to close.
A long long time ago, it was powered by the water that ran out to the St. Lawrence River. But only a long time ago, it was powered by steam. Old machines and materials from the paper mill are exhibited inside the museum to give visitors a feel of what industrial Quebec looked like in the last century.
Underground, there’s a water pump exhibit. Outside, there’s a water tower and an interpreted viewpoint too look out to a marina where wood once floated awaiting processing into paper pulp.
