The women were found nearly two weeks apart in the same apartment complex in New Westminster, prompting the RCMP to issue a public warning to sex workers earlier this week.
Police say autopsy results are inconclusive and further forensic and toxicology testing is being done.
Forty-five-year-old Jill Lyons was found Aug. 12 and forty-eight-year-old Karen Nabors was found Aug. 25.
The RCMP have said initial evidence suggested Lyons' death may have been a suicide, but investigators are treating the deaths as suspicious because both women worked in the sex trade, lived in the same building and knew each other.
Police are warning anyone in a high-risk lifestyle to remain vigilant and investigators have repeated their plea for anyone with information.
An advocate for the legalization of sex work says the deaths have frightened women who work as escorts, prompting some to panic and others to close up shop for a while.
