According to Sgt. Alex Mulvihill, the homeowner returned to the residence at 9:45 p.m., PT Monday night and found the woman in medical distress.
B.C. ambulance services attended but the woman died on scene. Mulvihill said the house is known to police.
"The female was declared deceased at the scene. At this point we are deeming it to be a suspicious death," said Mulvihill.
Investigators are still determining the cause of death, particularly whether the woman met with foul play. Police were on scene Tuesday afternoon interviewing witnesses.
He said until the coroner completes an autopsy, RCMP will be holding the scene at the house.
