Several hundred pigs perished in a fire that tore through a pigsty in Saint-Samase, south of Saint-Hyacinthe, in Monteregie.
The flames broke out Thursday evening.
No one was injured in the fire.
Firefighters from a few municipalities in the area helped control the fire, which ultimately destroyed the barn.
The damage is estimated at $1 million.
The cause of the fire is still unknown, but authorities say it wasn't criminal in nature.
