'I don't want to speculate anything.' - Sgt. Jack Poitras
RCMP spokesperson Sgt. Jack Poitras said he does not believe anyone was found alive in the home when officers arrived.
No one is in custody.
Poitras could not say if the 911 call came from within the house.
The RCMP's major crimes unit has been called to the scene.
Poitras wouldn't say if RCMP are investigating the incident as a murder-suicide.
"I don't want to speculate anything," he said. "It speaks volumes when we are not looking for anyone in regards to this at this time."

'It's sad and scary'
Police forensic investigators could be seen walking in and out of the two-storey home, which is in a quiet suburban neighbourhood.
A truck remained parked on the driveway. Two snowmobiles sat on a trailer beside the truck.
Melanie Balfour, who lives directly across from the home, said she didn't see or hear anything unusual Monday morning until her husband told her police were outside.
Balfour said three people lived in the house, and she used to see a little boy and a dog around the home.
"Right away when I saw the forensics I knew something awful had happened just by seeing it," she said.
"It's just sad … it's Christmas time and whatever, but you know what, it's sad and scary."
