A body was discovered Sunday morning following a fire in Lac Bouchette, near Saguenay-Lac Saint Jean.
The Sureté du Quebec is investigating the death as a possible murder.
Sgt. Louis-Philippe Bibeau said police were dispatched around 5:00 a.m. Sunday to Chemin du Barrage, where a cabin was still burning.
Crews searching through the rubble discovered the body.
Sergeant Bibeau said police arrested a man later in the day, but did not provide details about the victim or the suspect.
The cottage is considered a "total loss," said Bibeau.
