Police began an investigation in January after receiving a request from a family member to check on the welfare of the 18-year-old alleged victim, who was believed to be in Calgary.
Shortly after, officers located the woman at a bus station. She told police she had been held against her will and forced to work in the sex trade since the fall.
It's believed the woman arrived in Calgary in October 2013 for a job and was looking for a female roommate.
She met a woman who offered her inexpensive rent, which she accepted.
After a short time living together, it's alleged the homeowner began slipping drugs into the alcoholic drinks the two were consuming together.
Police say the homeowner then allegedly took inappropriate photos of the 18-year-old without her knowledge and later used those photos to extort her into participating in sex acts for money.
During the investigation, another female came forward alleging she had been the victim of voyeurism and extortion, by the same woman.
