The British Colombia coroner's office confirmed that they will "definitely" not have Cory Monteith's toxicology or autopsy report on Monday. "We might well have an update tomorrow, but final cause of death might be several days or even a couple of weeks after that," a rep for the coroner said in a statement.

According to Chief Constable Doug LePard, the 31-year-old Canadian actor, whose last known film role was playing a drug-addicted hustler sent to prison on a murder rap in the gritty indie movie McCanick, checked into the hotel on July 6. The star reportedly also had several people in his hotel room on Friday night, however a surveillance camera caught video of him returning early in the morning to his room alone.

News broke Saturday night that Monteith's body had been discovered earlier that day when staff members discovered the body after checking on the actor who had missed his checkout time. Monteith's cause of death is currently unknown, but no foul play is expected. Monteith made headlines recently when he completed a month-long stint in rehab in April.

Josh Waller, the writer/director of Monteith's last film McCanick, told ET Canada, "[Cory] had expressed that he was kind of going through a rough time, but that he was feeling better about it, and then when I saw him at the screening he wrote me a really sweet email." The director also noted that he had no hesitation casting someone who had a past substance abuse problem. "He was like: I can do this character, I know this character, I was this character, I have lived elements of this. He said I was a troubled youth." Waller also added, "He was so charismatic and passionate about the material it was just a combination of everything that made me think this guy was going to do it."

The Canadian actor and costar Lea Michele had been dating for more than a year at the time of his death. A source told Us that the twosome was, "100 percent happy and together and in love" and were "planning on moving in together after he got back from Vancouver." Michele has yet to release a statement but her rep said, "We ask that everyone kindly respect Lea's privacy during this devastating time. Thank you."

Monteith's fans created a memorial in the Glee star's honor and placed flowers and heartfelt notes outside the Fairmont Pacific Rim Hotel.
