Opémisca Copper Mines operated the community's mine until 1991. More recently, with the closure of the mines, the community's primary industry has been forestry. The community opened the first cogeneration plant in Quebec to produce electricity from the sawmill's waste matter.
On the night of January 1, 1980, at 1:30 a.m., 48 people were killed when a fire destroyed the Opémiska Community Hall. Fifty others were injured and rushed to Chibougamau hospital. This fire was the worst to occur in Quebec for more than 40 years. The fire started in wreaths of dried branches and other Christmas decorations, and the ensuing chaos that followed quickly blocked access to the main entrance. Several people managed to escape in time, but the tragedy left deep scars in the community.[5]
The community, and the efforts of its residents to keep it alive in the face of economic decline, are profiled in the 2013 documentary film Waiting for Spring (En attendant le printemps).[6]
