On Sunday morning, at about 10 a.m., police responding to a call found the body of a woman inside her home on Notre Dame Street in L'Épiphanie.
Quebec provincial police Sgt. Benoît Richard said information led officers to Rawdon, a nearby municipality, where they discovered the body of a man.
Police say it is unclear for the time being whether the two individuals were a couple, but at least one of the individuals did have children.
He confirmed that police are considering the hypothesis of a homicide-suicide.
"Obviously we are still at the beginning of our investigation and we still have a lot of things to verify," he said.
